Alan Baumgarten I will remember 2010 as the year the Internet became a more dangerous, more intimidating place. Make no mistake, I continue to be something of a Web apologist, and my stance on the value of Web-based learning has not diminished. On the contrary, there is more exceptional learning content available today than ever before. But the Internet has (and always has had) a dark side, and it is foolishness to focus only at the positive without occasionally looking back over one's shoulder at the negative. Here are just a few of this year's low points: • Wikileaks. 2010 is the year we learned how destructive information could be in the hands of a person who lacks convictions. Even more concerning to me than the immediate political repercussions of what Julian Assange published – and how little governments could do stop it – is that Assange will long be admired and emulated by every antiestablishmentarian teenager in the world with a few hacking skills. • Stuxnet. Stuxnet We don't know who created it or how was delivered, but we do know that a virus was successfully used to cripple a controversial nuclear power plant in Iraq. The doors of cyberspace espionage and warfare have been opened, and we haven't even worked out the rules of engagement. • Privacy. The suicide of Rutgers University student Tyler Clementi came as a direct result of fellow students making a illicit recording of him in secret and streaming it out online. (The two students were charged invasion of privacy.) Cyberbullying is a growing trend and a big problem, but what concerns me more is how relatively easy and inexpensive it has become for anyone to invade the privacy of someone else. While there are many lessons to be learned from the Internet events of 2010, there are two obvious themes that connect these threads. First, the laws and the enforcement of laws governing the fair use of the Internet are inadequate to ensure the safety and security of those who use it. This is not likely to change anytime. Second, we must place greater emphasis on teaching the values of character, integrity, respect, and personal accountability. We will continue to be cautious and vigilant, but ultimately the Web cannot function if the overwhelming majority of its users do not conduct themselves in an honorable and trustworthy manner. ________ Learners Online – 2 – JANUARY 2011 The Big Bang & Beyond Lisa Kerscher The Big Bang is a high-energy story for explaining the origin of the Universe, but what is the evidence that supports that theory? Take students on a tour to explore these observations, while demonstrating that this story’s end remains unwritten. H umans are curious creatures, infinitely seeking to explain the world’s workings in familiar terms and frameworks. For millennia, philosophers led the charge to explain how and why the cosmos seemed to exist and revolve. With the advent and evolution of scientific thought and measurement, however, the traditional philosopher’s role for explaining the Universe, in many ways, has been passed to the scientist. Folkloric tales of gods birthing the Earth and stars has generally yielded to mathematical equations and concepts of physics. Even so, these modern stories remain based on what is familiar to us, what we can measure, blended with a good dose of variable conjecture. NS9-12.4 Earth and Space Science • Origin and evolution of the Universe TEKS §112.36. Earth and Space Science (4) Earth in space and time. The student knows how Earthbased and space-based astronomical observations reveal differing theories about the structure, scale, composition, origin, and history of the universe. (A) evaluate the evidence concerning the Big Bang model such as red shift and cosmic microwave background radiation and current theories of the evolution of the universe, including estimates for the age of the universe. Fortunately, our view and understanding of the cosmos is always evolving. As Stephen Hawking states in his latest book, The Grand Design, “[Recent discoveries and theoretical advances] lead us to a new picture of the universe and our place in it that is very different from the traditional one, and different even from the picture we might have painted just a decade or two ago.” For example, although Edwin Hubble, in 1929, found evidence that the Universe is expanding, it was not until 1998 that two independent teams of scientists discovered that this expansion is actually accelerating. What’s the Story? Before diving into the origin and evolution of the universe, an excellent starting point is showing how today’s scientists think the ________ Learners Online – 3 – JANUARY 2011 universe is generally structured. The Known Universe, a 6-minute video in the American Museum of Natural History’s ‘Science Bulletins’, provides that perspective and context. The journey illustrates the known universe as mapped through astronomical observations. The video can be viewed within the Web page or downloaded and viewed full screen. To bookmark or download the video, use the Story Tools, which can be opened by clicking the big white plus-sign in the red circle located just below the video player. Starting in the Himalayas, the video leads viewers outward, describing key features along the way. The tour stops at the outer limits of scientific observation and understanding, before returning to Earth. In another Science Bulletins module, watch the video explaining how scientists are studying Our Expanding Universe. Students observe an easy-to-understand explanation of how scientists measure redshift and learn about the current dark matter energy survey, which is examining about 300 million galaxies. In addition to measuring redshift, astrophysicists also focus on studying what is known as Cosmic Microwave Background (CMB) Radiation. CMB radiation is the oldest light in the universe–radiant heat left over from the Big Bang, and scientists believe that it contains a wealth of information about the conditions of the early universe. Star Stories provides some interactive insight into some of the contributions in this field. In the ‘Star Stories’ section (versus the Timeline section), students will find a story titled, ‘The echo of the Big Bang’. To navigate through the story, students should click what “chapter” they want to explore and then click the bottom center text box to close that chapter of the story and return to the chapter selection screen. The story’s contents include a brief description of Cosmic Microwave Background Radiation, the Big Bang, and the “first light.” It also features the Nobel Prize winners who first discovered CMB radiation in 1965 and others who were instrumental in developing NASA’s Cosmic Background Explorer (COBE), which launched in 1989 and precisely measured and mapped the CMB radiation. Students will also learn that the Wilkinson Microwave Anisotropy Probe (WMAP), a follow-up mission that launched in 2001, helped scientists narrow down the age of the Universe to 13.7 billion years and that stars first formed around 200 million years after the Big Bang. ________ Learners Online – 4 – JANUARY 2011 To provide students a dose of how science has led to our current theories on the origin and existence of the universe, a summative narrative can be found at a site called The Big View. In the Spacetime section, have students read the introduction and The Universe pages. On a Mission Send students to the NASA Science–Astrophysics for their next leg into cosmic understanding. Begin with the question: “In what ways do measuring cosmic energy and objects help scientists understand how the Universe evolved over time, and also give a glimpse into its origin?” Write the question on a classroom board for ongoing reference. Tell students that an acceptable answer will identify: what is being measured, how it is measured, and how it specifically contributes to understanding the origin/evolution of the Universe. To research answers to that question, have small teams explore the Big Questions, such as “What are the origin, evolution and fate of the Universe?”, “How do planets, stars, galaxies and cosmic structure come into being?”, and “When and how did the elements of life in the Universe arise?” Also, point students to the Focus Areas, specifically The Big Bang, Dark Energy, Dark Matter, and Galaxies sections. In the Missions section, ask students to read the site’s short descriptions of the COBE and the WMAP. For more in-depth information about the WMAP, direct students to The Wilkinson Microwave Anisotropy Probe (WMAP) Exhibit in the Satellite Showcase at NASA’s Imagine the Universe site. This exhibit explains how WMAP’s mission was to help scientists clarify The Foggy Universe and to better grasp The Shape of the Universe, Formation of Structure in the Universe, How Old is the Universe. Lastly online, prompt students to take a peek at the James Webb Space Telescope, expected to launch in 2014. It will be the next generation collector of CMB radiation and other data that connects the Big Bang to our galaxy’s existence. Wrap-up the exploration by having each group share one or more answers to the question. ________ Learners Online – 5 – JANUARY 2011 Reflecting on the Universe During this lesson, students have reviewed animations, stories, and descriptions about how modern science has measured and theorized about the origin and evolution of the Universe. Now, students get their turn to tell a story about the Universe. Group students into small cooperative teams. Consider assigning students so that each team includes a balanced mix of skills in science, writing, and media. Tell students that they will develop a story through which the audience gains a better understanding of how scientists have generally concluded that the age of the Universe is about 13.7 billion years and that stars first formed around 200 million years after the Big Bang. Direct students to use the sites they explored during this lesson, but also encourage them to be creative in their storytelling, which may include some speculation and prediction. Also, allow teams to select varied formats. For example, teams could develop a video as a sci-fi drama episode, an animated cartoon, a documentary news story, or a series of audio podcasts. Instruct students that their stories should answer one or more questions, which may include: • Why and how do scientists study cosmic microwave background radiation and/or redshift? • Why do scientists seek to examine regions farthest away from us to understand the origin and evolution of the Universe? • How have specific NASA missions contributed to understanding of the Universe? • How would you describe the Big Bang and the space time that has followed? • What new evidence could change the current estimate of the age of the Universe? • What do you predict the Universe’s structure will look like in another 14 billion years? How about in 50 billion years? Instruct teams to integrate facts with their fiction, making sure to include references as applicable and cite sources somewhere in ________ Learners Online – 6 – JANUARY 2011 their production. Have students experience each team’s production and discuss.

It states that for any right triangle, the area of the square which side is the hypotenuse (the side opposite of the right angle) is equal to the sum of the areas of the squares which sides are the two legs (the two sides that meet at a right angle). This theorem is often written in the form of an equation: a2 + b2 = c2. S tudents first encounter Pythagoras in middle school and then continue to explore the theorem and its applications throughout their math experience in high school. The gap between the time students first work with the Pythagorean concept in middle school and when they apply it in higher level geometry and trigonometry courses later is substantial. Oftentimes, the introduction to this theorem is merely a glance-over and not a full (and necessary) exploration of the concept. Providing middle school students with a sound base for comprehending the implications of this very important equation will enhance their learning in later math explorations. NM-GEO.6-8.1 Analyze characteristics and properties of two- and threedimensional geometric shapes and develop mathematical arguments about geometric relationships. Create and critique inductive and deductive arguments concerning geometric ideas and relationships, such as congruence, similarity, and the Pythagorean relationship. TEKS §111.24. Mathematics, Grade 8 (7) Geometry and spatial reasoning. The student uses geometry to model and describe the physical world. (C) use pictures or models to demonstrate the Pythagorean Theorem (9) Measurement. The student uses indirect measurement to solve problems. (A) use the Pythagorean Theorem to solve real-life problems Students gain comprehensive insight into the Pythagorean Theorem through a variety of online explorations, demonstrations, and activities. What is the Pythagorean Theorem? The Pythagorean Theorem can be used with many realworld applications: calculating the distance between points on a plane; finding perimeters and surface areas and volumes of a range of geometric shapes; and computing the maximum/minimum values of perimeters and surface areas and volumes of various geometric spaces. The key is getting students to realize that this theorem is not just important, but actually used in a wide range of applications in everyday situations. For example, tell the class that they ________ Learners Online – 8 – JANUARY 2011 will be receiving a new 65-inch 3D TV for their classroom (considering these currently retail for around six thousand dollars, this should grab their attention). Remind them that TVs are measured by their screen diagonally. Before you let them down and tell them that this is a theoretical TV just for a math exploration, point out that they will need to figure out if it will fit on the bookshelf that measures 54 inches in width and 35 inches in height. Move students forward with a very basic introduction to Pythagoras’s famous discovery from Math is Fun. Project this site for the whole class and work through the page making sure to play the animations (repeat them to make sure all students understand) and follow through the worked examples. Follow up with the introductory video, Pythagorean Theorem Lesson (from Doina Popovici’s CRCT Preparation). Next move on to a more complete overview of Pythagoras from MathsNet. Start with the page about the mathematician philosopher and then click through the blue tabs at the top. Under ‘Proofs,’ click through each of the five proofs. For gifted and talented students, point them to the Construction 1 activity for later completion. Follow this lesson with some more video examples by playing the clips listed at Online Math Learning’s Pythagorean Theorem link. Time to Play Allow students to work in pairs for the next Web activity. Point them to Pythagorean Puzzle from PBS. Read the lesson and the graphic. They should try to Demonstrate the Pythagorean Theorem Flash interactive. Move next to An Interactive Proof of Pythagoras’ Theorem from the University of British Columbia’s Mathematics Department. Read the instructions in the gray box for each step. Observe the diagram for each as well. Students may wish to create a set of diagrams that illustrate each step of the proof in their math journals. Now tell students it is time ‘play.’ Ask them to think back to when they were young children playing with blocks and tiles. They will get to play with the digital geometric shapes in these applets. Divide the class into three groups. Each group will work with one of the following activities. Within each group, pair students up to explore the applets. They should keep notes of their observations. ________ Learners Online – 9 – JANUARY 2011 After eight to ten minutes, have the students pair up with someone from the other groups in order to then share their online activities and ‘teach’ each other how to use it. Allow five to eight minutes for students to work. Have them switch once more so that all students will have experienced each of the three activities: • Pythagorean Theorem (Manipula Math) – read the instructions on the page • Pythagorean Explorer (Shodor Interactivate) – click the Help tab for instructions then continue with the Activity tab • Pythagorean Puzzles (Utah State University) – read the instructions located at the right. If students thought playing with shapes was fun, they will really enjoy trying to escape an ancient Greek Minotaur as they search the Temple of Oracle at Delphi to find out about the mystery of Pythagoras. Pair students up to work through this exciting interactive module, Math and the Greeks from Discovery Education. Now that students have enjoyed a thorough exploration of the Pythagorean Theorem, return to the problem posed to the class about the brand new TV, they will have figured out that the shelf space is a mere 84 square inches too small for that TV. Tell them not to be too heart-broken, it was a hypothetical TV used to help students recognize the value of implementing the Pythagorean Theorem in a real, everyday situation. The TV, sadly, was never real.

This year, invite students to open their minds by first opening their ears. Explore Dr. King’s continued significance through music. M ENL-ENG.K-12.2 UNDERSTANDING THE HUMAN EXPERIENCE Students read a wide range of literature from many periods in many genres to build an understanding of the many dimensions (e.g., philosophical, ethical, aesthetic) of human experience. TEKS §110.42. English I (19) Viewing/representing/ interpretation. The student understands and interprets visual representations. (B) analyze relationships, ideas, and cultures as represented in various media; artin Luther King, Jr. and Christopher Columbus are the only historical figures who never served as President for which the Federal government commemorates with a day of recognition. This August the Dr. Martin Luther King, Jr. National Memorial opens on the Mall in Washington, DC. Forty-two years after his death, Martin Luther King, Jr. remains relevant. Today’s students, may be most familiar with his I Have a Dream speech; it is worthy of studying. However, it is not the only way to access Dr. King’s legacy. This year, ask students to don some headphones and revisit Dr. King’s contributions by listening to music inspired by his work and his times. The History of a Day Begin by asking students what we commemorate on this day, and why. List the terms they associate with Martin Luther King, Jr. on a cluster map. Ask students to share their thoughts and record each suggested term. Place a small tally next to those that are mentioned repeatedly. For visual learners, you might also post photographs or printouts of key terms. (Have photographs available for key terms or names you expect will come up.) Briefly review the map and how terms related to each other. Martin Luther King, Jr. was assassinated on April 4, 1968. Nearly two decades later, President Reagan signed the bill into law that created Martin Luther King, Jr. Day. Rarely do we consider ________ Learners Online – 12 – JANUARY 2011 how or why a holiday is born. Revisit ABC News correspondent Sam Donaldson’s coverage of that moment. Donaldson’s story suggests everyone did not support the holiday. Who was opposed and why? To learn more about the history of Martin Luther King, Jr. Day and the politics that affected its creation, read Time magazine’s article ‘A Brief History of Martin Luther King, Jr. Day’. For a longer explanation of the history of this day, read the New York Times article, ‘Broader Acceptance Sought for King Holiday’. Ask students to discuss whether things have changed since the New York Times article was written. The Music for a Man The Civil Rights Movement was a complex collection of many events that required the work and sacrifice of countless people, many of them unsung, historically anonymous heroes. It was not a chaotic, spontaneous Movement but an orchestrated, organized one from which Martin Luther King, Jr. emerged as the most recognizable leader. His speeches resonated with audiences then, and his words remain politically and culturally relevant. A handful of songs celebrate Dr. King’s life. However, Dr. King’s work cannot be separated from the Civil Rights realities of his times. Thankfully, YouTube.com offers many of these songs with videos featuring historical footage. YouTube does not edit the content or quality of the videos users post; nor, does it restrict user comments. For some school districts, these are reasons to block YouTube. Surely, they are reasons for teachers to preview pages. However, among YouTube’s vast array of videos are many of merit. Oftentimes, it is the only place to find a video with legitimate links to the classroom, free of charge. The videos below each feature a song that was inspired by Martin Luther King, Jr. accompanied by historical photographs, headlines, or video footage. Sound and sight together packs a powerful punch. Conduct a jigsaw activity in which small groups of students watch and discuss one video each. To model this, show the class Sam Cooke’s classic Civil Rights song, ‘A Long Time Coming’. The video that accompanies it begins with scenes from the Civil Rights Movement (many drawn from the PBS series, ‘Eyes on the Prize’) and closes with an excerpt from President Obama’s presidential victory speech. For a more provocative ________ Learners Online – 13 – JANUARY 2011 discussion, play only the audio of the song first—without the video or the Obama excerpt. Ask students to share the images the song conjures. Then, play it again with the video and excerpt. Was it what they imagined? How does President Obama’s excerpt alter the meaning of the song? How do the song and images connect to their earlier discussion? What would they add to the cluster map? What questions does the video raise? (Little bit of trivia: Obama was nominated for President at the Democratic Convention 45 years to the day that Dr. King gave his ‘I Have a Dream’ speech.) Assign student groups one of the following songs/videos. Students may benefit from watching the video repeatedly: once to take in both audio and visual components and to record initial reactions, a second time to listen to the lyrics, and once again to examine the images with no sound. Ask a representative from each group to report to the class what they heard and saw in the video: the message of the lyrics, how the images/lyrics connect to the cluster map discussion, what they add to their understanding of Martin Luther King, Jr. and his times, how the lyrics and images work together to deepen your understanding of each, what questions they raise, and the one clip that resonated most with the group. Dion’s ‘Abraham, Martin, and John’ remembers four historical figures who each fought for civil rights. Students might wonder: How did Martin Luther King, Jr. free a lot of people? What do Abraham Lincoln, Martin Luther King, Jr., and John (and Bobby) Kennedy have in common? Explain these lyrics: “Didn’t you love the things they stood for? Didn’t they try to find something good in you and me?” Pause on the first screen to consider the four quotes. Explain each. What connects them? Explain which quote resonates most with you. Patty Griffin’s ‘Up to the Mountain’ refers to the final speech Martin Luther King Jr. gave, the day before he was assassinated. Who is the speaker in the song? What is the peaceful valley she sings about? What is the mountain? What do the images reveal about Dr. King or the Civil Rights Movement? The text at the end of the video is an excerpt from that speech. If want students to watch an excerpt of that speech, YouTube has that, too. ________ Learners Online – 14 – JANUARY 2011 Dudley Randall’s poem, ‘Ballad of Birmingham’, became the basis for the song, ‘Ballad of Birmingham’. Both recount the tale of a child whose mother refuses her request to go downtown to march. Instead, her mother sends her to church, believing she will be safer there, only to be killed by a bomb. The poem refers to the 1963 bombing of Birmingham’s 16th Street Baptist Church in which four young ladies died. Dr. King delivered the eulogy at their funeral. Summarize for your classmates the story told in the poem and song. Which version did you prefer—song or poem? Dr. King’s iconic speech, ‘We Shall Overcome’, incorporated the refrain of the Civil Rights song of the same title. For a closer look at the simple lyrics, view Pete Seeger’s version. Finally, fast forward to 0:50 for video of the crowd at the 1963 March for Jobs and Freedom in Washington, DC singing the song with Joan Baez. Why has this simple song become a lasting symbol of the Civil Rights Movement? For many, Dr. King’s lasting legacy lies in acknowledging the continued work necessary to attain civil rights, and socio-economic and educational equality, and for us each to contribute toward the vision embodied in ‘I Have a Dream’. For some, Martin Luther King Jr. Day is not a day of remembrance, but a day of service. In observance of MLK Day of Service, individuals may partake in community service events across the United States on January 17, 2011. Simply enter your zip code and view a list of local service opportunities. Challenge students to consider how they might serve their communities. What needs exist; what talents do they possess? As a final, independent reflection, ask students to share their thoughts on the day’s discussion: What images or songs resonated with them? Do they support a holiday for Dr. King? How do they think it is best observed? Has their understanding of the Civil Rights Movement or Dr. King changed? In August, 2011, the Martin Luther King, Jr. National Memorial opens on the Mall in Washington, DC. (For a sneak peek, open the Washington Post article and slideshow.) His monument joins monuments honoring the crafter of the Declaration of Independence, and the Protector of the Union. Clearly there is something special about the man. Students deserve to understand why 50 states in the nation honor his leadership and ministry with a State holiday. By celebrating him we recognize the sacrifices and ________ Learners Online – 15 – JANUARY 2011 contributions of those who marched before, with, and after him. Students deserve to examine the road we have traveled and to look to the road ahead. How else will they choose the road less taken?

Who will win? I n the fifth century BC, the Persian Empire was the dominant force in Mesopotamia and one of the largest in terms of geographic size in world history. By the late 400s BC, the Persian Empire started to stretch southward into the Greek city-states. The conflict that ensued between the Greeks and the Persians is known as the Greco-Persian Wars or sometimes simply just as the Persian Wars. The Persians Wars spanned several decades and was full of intrigue, great leaders, and magnificent battles. It was a defining moment for both Persia and Greece - the end of an era for one and a beginning of an era for anther. Students will be mesmerized as they take a trip back into time and learn about the Persian Wars. A Little Background NSS-WH.5-12.3 ERA 3: CLASSICAL TRADITIONS, MAJOR RELIGIONS, AND GIANT EMPIRES, 1000-300 BCE The student in grades 5-12 should understand how major religions and largescale empires arose in the Mediterranean basin, China, and India, 500 BCE-300 CE. §113.33. World History Studies 1) History. The student understands traditional historical points of reference in world history. The student is expected to: (B) identify changes that resulted from important turning points in world history such as the development of farming; the Mongol invasions; the development of cities; the European age of exploration and colonization; the scientific and industrial revolutions; the political revolutions of the 18th, 19th, and 20th centuries; and the world wars of the 20th century; Before examining the Greco-Persian Wars, first review more about the major players involved: Athens, Sparta, and Persia. Athens and Sparta were just two of the many city-states that made up ancient Greece. During the fifth and fourth centuries BC, Athens politically and culturally dominated the other city-states. Visit BBC’s site on the Ancient Greeks to learn Why Athens was So Great. Then click the link in the left bar to find out about ‘Life in Athens’. Then, watch a short video excerpt of Lost Worlds – Athens- Ancient Supercity hosted by WatchKnow. While many know Athens best for its democracy, Athens was also a naval powerhouse. Learn what made Athens’ navy so powerful by watching the first three minutes of a ________ Learners Online – 17 – JANUARY 2011 YouTube video called Athenian Navy. While Athens dominated many aspects of Ancient Greece during the fifth and fourth centuries BC, Sparta’s strength lay in their military. Visit BBC’s site on Ancient Greeks and read the articles about Sparta’s Soldier-state .Next click ‘Growing Up in Sparta’ in the left bar. For a video introduction to Sparta, watch the animated History Channel video entitled Spartans. Then to learn more about the Spartan army watch the History Channel videos: Spartans: Deconstructed, Spartan Boot Camp: Killing Machines, and Battle of Thermopylae: Spartans Prepare. From the 600s to the 300s BC, Persia dominated Mesopotamia. Led by rulers such as Cyrus the Great and Darius I, Persia stretched her borders as far west as Egypt and as far east as the Indus River. Watch an excerpt of Engineering an Empire – The Persians and Persepolis Recreated both hosted by WatchKnow to learn about Persia’s great empire. These great powers collided when the Athenians lent their support to the Ionian Greek city-states during their revolt against Persia. In 498 BC, Athens conquered and destroyed the Lydian capital of Sardis, but soon lost interest in the revolt. Persia under the rule of Darius I eventually regained control over the rebellious Greek cities in Asia Minor and decided Athens deserved punishment for their role in the destruction of Sardis. The Persian Wars had begun. The Wars In 490 BC, eight years after Athens had destroyed Sardis, Darius I launched an attack against Athens. The Athens led by former Persian soldier Miltiades met the Persian army at Marathon in Attica. The stakes were high. The Persians had the most powerful army in the world and an Athenian loss would result in Persians gaining control of Greece. Watch a narrated and animated video of the Battle of Marathon to gain an overview of the battle and then watch Battles BC: Battle at Marathon both produced by the History Channel. Then, read Herodotus’ account of the battle at Eyewitness to History. Even though they were outnumbered, the Athenians were victorious at Marathon. After the battle, the Greek army quickly marched back to Athens and successfully prevented a Persian attack on the city. ________ Learners Online – 18 – JANUARY 2011 After the Battle of Marathon, the Persians retreated. Problems at home prevented Darius I from staging a second attack. In 486 BC, Darius died and his son, Xerxes became king of Persia. Xerxes did not stage a second attack until 481 BC. During this time, Themistocles convinced his Athenians to invest the profits of a silver mine into building an navy. Learn more by watching a YouTube video, The Brilliance of Themistocles. By the time Xerxes launched his attack, the Athenian navy had two hundred ships, but would it be enough to stop the Persians? Go to the History Channel and watch a video about King Xerxes and His Master Plan to find out. Then go to Edsitement and see if you could build bridge across Hellspont like Xerxes. Lastly, go to the British Museum’s site on Ancient Greece and read the Story, Explore the Battlefield at Plataia, and see if you have what it takes to command a Greek trireme. Despite the creation of a large Athenian navy, by 480 BC Xerxes’ Persian army and navy had ransacked much of the northern Greek city-states and were pushing south. As the Persians marched through destroying the Greek city-states, a Greek force of approximately seven thousand gathered to block the pass at Thermopylae. A vicious battle between the two sides ensued. First, watch a History Channel video to learn How the Battle of Thermopylae Unfolds. As the two sides fought each other, a Greek traitor revealed a path to take the Persians behind Greek lines. In a heroic last stand, King Leonidas of Sparta dismissed the majority of his forces and guarded the pass in a famous last stand. Learn more about the last stand of King Leonidas and his three hundred Spartans by watching a History Channel videos: Last Stand of the 300: The Kill Zone and the Battle of Thermopylae. News of the devastating loss at Thermopylae spread throughout Greece, but a turning point was right around the corner during a naval battle, the Battle of Salamis. During this battle, the Greeks lured the Persian navy into the treacherous Straits of Salamis. While the Persian ships struggled to maneuver through the straits, the Greek triremes rammed and sank the Persian ships. In all, the Persians lost about three hundred ships while the Greeks lost about forty. First, view a map of the Battle of Salamis. Then, watch a video on YouTube called the Battle of Salamis that summarizes the events leading up to Salamis and the actual battle. ________ Learners Online – 19 – JANUARY 2011 After the loss at Salamis, most of the Persian army withdrew from Greece. However, one Persian general, Mardonius, and his men stayed in Greece through the winter. In 479 BC, he was attacked and killed at Plataea (also spelled Plataia) by the largest army the Greeks had ever gathered. The end of the Persian Wars ushered in the Golden Age of Athens. Led by Athens, many Greek city-states joined in a defensive alliance against future Persian attacks called the Delian League. However, this alliance was shortlived as the city-states soon became embroiled in a war of their own – the Peloponnesian War.

Yes, it is a bit cold, but with proper clothing you and your students have a natural laboratory to explore to your heart's content! T eaching a unit like this enables your students to dream and imagine. The distances are so vast in space that “the amount of space in space” is hard to conceive. This will certainly grab your students’ attention as you begin the unit by displaying some great photos and use the Zoomer tool to explore “where we are”. Students will explore links to online content that will facilitate the study of basic astronomy. They will learn what is “out there” and where Earth “fits” in the grand picture. The amount of “space in space” is illustrated in various ways throughout these activities. Where are we? NS.K-4.4 As a result of activities in grades K-4, all students should develop understanding of earth and space science, including a basic understanding of astronomy and the night sky. TEKS §112.16. Science, Grade 5 (8) Earth and space. The student knows that there are recognizable patterns in the natural world and among the Sun, Earth, and Moon system. The student is expected to: (A) differentiate between weather and climate; (B) explain how the Sun and the ocean interact in the water cycle; (C) demonstrate that Earth rotates on its axis once approximately every 24 hours causing the day/night cycle and the apparent movement of the Sun across the sky; and (D) identify and compare the physical characteristics of the Sun, Earth, and Moon. “Where is Earth?” Prompt students with this insightful open-ended question. Then compile their answers. Use this question as a “launch point” for the ensuing activities. By asking such a question, you will be raising their awareness of their surroundings and gaining a sense of how they view our planet and its position in the Universe. The Zoomer Applet, provided by the Physics Department at Weber State University allows you and your students to answer that question precisely. This tool is essentially a simple slide bar where you begin “zoomed in” on Earth and you can gradually (or rapidly) zoom out to view the entire Universe. Using the Zoomer Applet, you can easily and rapidly establish that Earth is a planet with one moon revolving around it. The animation even illustrates where geosynchronous and GPS ________ Learners Online – 21 – JANUARY 2011 satellites are found. The slide bar moves vertically up along the right side of the simulation to create a larger and larger view that attempts to illustrate scale along with relative location. As you scroll outward, you cross the Moon's orbit and the Inner Planets; then the Sun come into view. Pause here and consider engaging your students with the exploration of our nearest neighbors. Many great sites exist including The Solar S ystem, a site designed by second grade students and hosted by the Southern Indiana Education Center. This site facilitates the study of the inner planets. Break the class up into teams with each team exploring one of the four celestial bodies (Mercury, Venus, Mars, and our moon). Click each planet for a brief description along with one of the author’s drawings. An approach asking them to compare and contrast each body to Earth will ensure that each group studies key aspects of our planet along with these foreign bodies. Focus on aspects including composition, general environment, atmosphere, etc. NASA also has outstanding resources on each planet, along with great photos. Returning to the Zoomer Applet, continue widening your view. Take notice of the scale tool, which is enabled by checking the box in the lower corner. It is located at the bottom of the main view, the units are in “light distance” - light years, light minutes, light seconds, from Earth. Have students create an outline of what they encounter as they travel farther and farther from Earth. As you exit the solar system, notice the presence of the Kuiper Belt (Pluto is one of the largest members of this belt of icy – cold bodies) and the current locations of a few man made probes launched in the 1970's. As you continue to widen your view, you will reach the nearest stars (at a distance of a few light years), then full galaxies, and finally the edge of the Universe! Enjoy the trip. Bring in some math by having students design a model Universe or solar system within your classroom. Lastly here is access to a great poster that provides a “Cosmic Perspective”. Point out some of the major features labeled on this poster. ________ Learners Online – 22 – JANUARY 2011 Watching the Night Sky Science Score has posted Watching the Night Sky, a great story that you can turn into an interactive lesson. Begin reading this story with students. You may wish to have them read it paragraph by paragraph as a class. Stop after each paragraph to solicit student input or to prompt thought and wonder. Specifically, after the first paragraph, have students identify whether they are in a city, suburban, or rural location. Ask them to name what they believe they have seen in the night sky. Use the second paragraph to reinforce what they worked on in the first lesson in this article. Use the 3rd, 4th, and 5th paragraphs to create a scale model of the solar system. Have students use the props named in the essay – a soccer ball, peppercorn, and peanut. Take your students outside and create a scale model of the solar system using individual students to mark positions. Once you have a student pace off Neptune, have students leave markers (pieces of construction paper perhaps) and then re-group the class to close the activity. With each of the remaining paragraphs, help students identify where these objects are found or originate. For example, satellites orbit Earth, and as such would be right next to the planet; meteors originate in the asteroid belt (between Mars and Jupiter), and comets are thought to originate in the Kuiper belt (recall this is beyond the orbit of Neptune). The visual impact of this activity should serve to reinforce Bill Nye's famous quip “There is a lot of space in space.” Operation: Imagination Constellation The Pacific Science Center has a great “hands-on” lesson written designed to help your students understand what a constellation is and even enables them to “design” and name their own. Create-A-Constellation provides complete instructions in a free, down-loadable PDF document for you and your students to follow. It is a great lead-in to observing the night sky and looking at the 'real' thing! The document is easy to follow and quite selfexplanatory. The activity concludes by presenting the learner with a scatter-dot pattern and asks the student to create their own constellation. Consider having each student create their own and ________ Learners Online – 23 – JANUARY 2011 then share with the class what they observe, then post their work in the classroom for all to view. This also provides a great lead for you to discuss the fact that different ancient cultures created their own constellations. Remember constellations are a purely manmade phenomenon. For more advanced learners, you may want to prompt them to consider the fact that stars within well-known constellations may be located at very disparate distances from Earth. That is, the stars in Orion's belt (one of the most easily recognizable winter constellations across the United States) are not all equidistant from Earth. In fact, one is relatively close and one is quite a bit farther. This leads to another revelation, if you were to travel away from Earth (FAR away from Earth) the star patterns would no longer would be recognizable! This is a concept that most people, not just elementary students have trouble with. Preparing to Study the Night Sky Thanks to innovative, interactive technologies, you can produce sky charts for your local area. This is an excellent approach to prepare students for what they can look for at the hour they go outside to observe. The Astroviewer, produced by astronomy enthusiast Dirk Matussek is a very user friendly tool. From Astroviewer's main page, click the Astroviewer Online logo in the upper-left corner of this page. You are now on the “find planets and constellations in the night sky” page. Click the “current night sky” link to create a sky map for the current night sky for the location of your choice. Use the dialogue box provided and select the nearest major city to your location. For example, if West Palm Beach, Florida does not produce a result, try Miami, Fl. The only limitation to this tool is it is “realtime”. You cannot adjust the time to view the sky at the time of your choosing. There is a viewer available for download, but, there is a small fee to gain full access to that viewer. As an alternative, Sky and Telescope's Interactive Sky Chart has an outstanding tool that can be adjusted to your location and to any time you wish to model the sky. You will need to create a (free) user account with Sky and Telescope, but once that task is completed, you can click the “Interactive Sky Chart” ________ Learners Online – 24 – JANUARY 2011 button on the left side of Sky and Telescope's home page and the interface will open and prompt you to select a location. The tools are fairly intuitive within the interface, you can select date and time and have views for both overhead (towards the zenith) and from the horizon (and you can select your view direction.) To change your orientation along the horizon, just click and drag and you can (for example) change a view looking west to a view looking north. Additionally, consider playing with the advanced display options to customize your view. Once you are within the Interactive Sky Chart, try stepping either minute by minute or hour by hour through the night sky view. Use this as a tool to familiarize students with the night sky and/or prep them for an evening activity where they are asked to identify something specific. Take advantage of this tool to ask students why the view would change throughout the night. Develop the concept that Earth rotates (spins on its axis) and in a 24 hour period completes one rotation. Challenge students to consider whether stars are still present during the day. The answer is yes, but the scattering of light in our atmosphere prevents us from seeing “into space” with the exception of the brightest celestial objects (such as the Moon). A Virtual Planetarium Paul Neave of neave.com has created a virtual Planetarium. Use your mouse to look around the sky; point to stars and constellations to access their names along with a celestial objects (star, planet or moon) brightness and distance (in light years or astronomical units). Recall, a light year is the distance light travels in a year; an astronomical unit is the distance between Earth and the Sun. Click the tool to begin studying the sky. Adjust date and time along with location (click the location to access a clickable world map) by latitude and longitude. Along with the sky chart detailed in the previous section, this tool provides students an excellent sense of what to look for. To start using the planetarium, select your location, and then ask students to search around for a constellation they recognize. They can use the star chart from the previous section to gain a sense of what they are looking for. Once they find a constellation, ________ Learners Online – 25 – JANUARY 2011 for example, Orion (be sure the date is a winter date and the time is after sunset), direct them to locate his belt and study the three stars that comprise his belt. Are they of equal magnitude (brightness)? Are they equidistant from Earth? Use this as an opportunity to reinforce the concept of a light year (approximately 600 trillion miles). The sky has been a source of fascination since the beginning of civilization. Studying the “heavens” will exercise students' imaginations, increase their sense of wonder, and build their powers of observation. While the study of constellations is not “hard science”, it can lead to core concepts in Astronomy, including the study of patterns, stellar magnitude, and distance.

They are the ones who finish the assignment before the rest of the class is on number two; the ones who seem to be able to remember facts almost before you have taught them. They are the children who often end up sitting at their desks waiting for the rest of the class to catch up. I n the best situations, accelerated learners may be able to help slower learners. In the worst situations, they become disruptive because they are bored. Most of them are probably in between – not harming anything, but not learning anything either. NM-NUM.3-5.1 Understand numbers, ways of representing numbers, relationships among numbers, and number systems TEKS §111.17. Mathematics, Grade 5 (5) Patterns, relationships, and algebraic thinking. The student makes generalizations based on observed patterns and relationships. The student is expected to: (A) describe the relationship between sets of data in graphic organizers such as lists, tables, charts, and diagrams; and (B) identify prime and composite numbers using concrete objects, pictorial models, and patterns in factor pairs. Explore some of the ideas for easy-to-implement activities that can be used to engage accelerated learners in mathematics. These fun projects encourage development of mathematical skills and competencies beyond the basics that may be taught in class. Perhaps most importantly, they can be completed largely independently, so the teacher is free to work with the rest of the class at the same time. Sudoku Do not laugh! Sudoku is a challenging game that fosters number sense and excellent problem solving skills. To solve even the most basic puzzle, students must be able to see patterns, make predictions, and think logically. More advanced puzzles require more advanced problem solving skills, so this game lends itself easily to almost any level of player. ________ Learners Online – 27 – JANUARY 2011 Daily SuDoku is an excellent source of Sudoku puzzles for both children and adults. The site has a section of puzzles aimed at kids, as well as an archive that lists past puzzles by level of difficulty. Click one of the kids’ puzzles in the archive to get a screen that lets you print the puzzle, switch from numbers to letters, and see the solution. Print puzzles at various levels from this site to keep on hand as activities for students who finish their regular work early. Once students understand how the puzzles work, you can challenge them to come up with their own. This is difficult, but is a very good exercise for accelerated math students. If you have more than one such student in your class, have them each make a puzzle and then switch to see if they can solve each other’s. Tangrams Tangrams provide another excellent problem solving exercise, this time with a geometric slant. A tangram is an ancient puzzle made of seven geometric shapes that can be assembled and reassembled into a huge variety of figures. The challenge is to assemble the pieces into a given shape, which is often much harder than it appears at first glance. The exact origin of the tangram puzzle has been lost to history, but it probably originated in China several thousand years ago. It has been around in the western world since the 1800s, at least. If a computer is available to your accelerated students, they can work with tangrams online at a number of sites. One of the best is from the National Library of Virtual Manipulatives. Click one of the grey shapes at the bottom of the screen. Then use the mouse to arrange the tangram pieces (without overlapping) to cover the shape. To flip a piece over, click the Flip button with the arrow on it. Students can also change the color of a piece by clicking a new color on the grid. This site also has a link at the top of the page for parents and teachers that explains more about how the game works, and a link that connects the game to the NCTM Standards. PBS provides two more Flash-based tangram activities, Tangrams and Tangram Game. Check TeacherStore’s Room 108 Tangrams for even more interactive fun. If no computer is available, students can still work tangram puzzles. Print out tangram templates on sturdy paper and have students cut out the pieces to make their own sets. Then print out puzzles and keep copies on hand. When students need additional ________ Learners Online – 28 – JANUARY 2011 work at math time, give them a new sheet of puzzles to try. Be sure to ask them to write about their solutions in their math journals to practice those communication skills. Other Games In addition to Sudoku and Tangrams, there are a great many mathematically-themed games students can play both online and offline. Shut the Box is another very old game that integrates problems solving skills with addition facts. Players roll a pair of dice, find the sum that appears, and then flip down tiles numbered 1 to 9 to make that sum in whatever way they choose. For example, if the dice show 4 and 5, the sum is 9, so the player could flip down just the 9, or 8 and 1, or 4 and 3 and 2, and so on. Then the player rolls again and tries to flip down the new sum using just the tiles that are left. The turn is over when there are no tiles left up that add up to the sum on the dice. Students can play this game individually or in pairs. The goal is to have the lowest sum left at the end of each turn. Remember Tetris? Well, it turns out to be a great game for practicing spatial reasoning. There are hundreds of versions available online, but many computers also have simple versions built in. Check your school’s computers to see if the original version from the eighties is still hanging around on them. There are a number of journal questions students can address about Tetris. Try asking how many shapes there are, or which shapes are easier to place, or which sequences of shapes are hard or easy. Be sure to encourage students to explain their reasoning. The key to engaging accelerated students is to implement variety and challenge. Be willing to offer a new activity if the old one seems stale or wrong for them. And do not be afraid to try activities that are not traditionally seen in the mathematics classroom. If it seems like math, it probably is math, and they will learn from working with it. No teacher likes to see a student bored in his or her classroom. Providing plenty of enrichment activities can prevent boredom for ‘those’ students and give them something to look forward to in math class again.

Hamilton After reading the story “Matilda” by Roald Dahl, you ask Denise for her opinion of the book. Denise begins to tell you that she liked the book, but cannot explain why. Using puppets, you ask Denise to act out her favorite part of the book. You take notes as Denise shares and then discuss these notes with Denise. Later, Denise is able to write a complete paragraph describing her opinion of the book. NL-ENG.K-12.12 APPLYING LANGUAGE SKILLS Students use spoken, written, and visual language to accomplish their own purposes (e.g., for learning, enjoyment, persuasion, and the exchange of information). TEKS §110.5. English Language Arts and Reading, Grade 3 (1) Listening/speaking/ purposes. The student listens attentively and engages actively in various oral language experiences. (14) Writing/purposes. The student writes for a variety of audiences and purposes and in various forms. L istening, speaking, and writing are skills that individual state standards and the Common Core English Language Arts Standards address, but separately. While working on one skill, you can and probably are addressing other skills. We will look at Web sites that address each skill individually, but also identify ways to combine these skills into everyday classroom lessons. Within the Common Core English Language Arts Standards at grade 3, are these specific Speaking & Listening Standards: • Determine the main ideas and supporting details of a text read aloud or information presented in diverse media and formats, including visually, quantitatively, and orally. • Report on a topic or text, tell a story, or recount an experience with appropriate facts and relevant, descriptive details, speaking clearly at an understandable pace. • Speak in complete sentences when appropriate to task and situation in order to provide requested detail or clarification. ________ Learners Online – 31 – JANUARY 2011 In grade 5, there is a higher skill demand for students: “Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly.” The Common Core Standards for writing are very similar for grades 3 and 5 in these areas: • Write opinion pieces on topics or texts, supporting a point of view with reasons and information. • Introduce a topic or text clearly, state an opinion, and create an organizational structure in which ideas are logically grouped to support the writer’s purpose. • Provide logically ordered reasons that are supported by facts and details. • Provide a concluding statement or section related to the opinion presented. Take some time to explore how to use listening and speaking activities to create writing that meets the standards within your state and the Common Core. Listening and Speaking: Classroom Strategies A fable is a short story which teaches a lesson. In small groups or in a computer learning center, students can listen, discuss, and respond to stories written by Aesop. Studyzone.org, a New York State Test Prep site, introduces students to Aesop through the “Tortoise and the Hare” fable. Click to hear the story while also reading it. Following the story are three comprehension questions. Click the “jumping hare” at the bottom of the page for another story, “The Fox and the Crow.” There are also comprehension questions to follow. Form pairs of students to listen to the story together. Then encourage them to have a short discussion about the main idea and supporting details of the story. Have students share what they think the moral or lesson for the story. Students should write a paragraph describing either the fable or the lesson learned. Addition al Aesop’s Fables can be found at the Penguin Publishing Group Web site. ________ Learners Online – 32 – JANUARY 2011 For additional audio stories, visit Storynory which has published a new audio story every week since November 2005. Older students may enjoy the “Educational” section of the site which features Greek myths, Robin Hood, and the Knights of the Roundtable. There are also classic fairy tales, original stories, and stories appropriate for very young readers. Teachers can create their own audio tapes of stories taken from classroom textbooks to support struggling students’ comprehension of text and to enhance listening skills for all students. To further develop listening and speaking skills, create a puppetmaking learning center in the classroom. Students create puppets of their favorite characters and act out their favorite scenes. After students have visited Debopriya Bose’s article on Puppet Makin g for Children, think about the type of materials you want to include in your center. Ask students to bring in clean, used socks and scrap fabrics to add to your center. Groups of students could create Reader’s Theater puppet shows based on the stories you have introduced to them or the scripts found at this Web site. Writing to Inform Asking students to “report on a topic or text, tell a story, or recount an experience with appropriate facts and relevant, descriptive detail” is one form of writing to inform. Show students the general format and examples of information writing with Writing Fun by Jenny Eather. Click “Information Report” under the column “Text Types” to see the how this type of writing is organized. There are six examples to share with students for a whole class discussion. Other types of writing to view on their own are Explanation, Discussion, Persuasion, Response, or Description. Consider matching one type of writing format with different stories presented in class. For more specific tutorials on how to organize writing, have students visit the OWL elementary Web site which describes the Six Traits of Writing: Organization, Voice, Sentence Fluency, Word Choice, and Conventions. Provide an opportunity to practice skills by using the Read, Write, Think essay map. Lastly, for English language learners, struggling students or to provide an opportunity to build listening skills, have students watch the video on paragraph writing. Students will hear the “paragraph song” and ________ Learners Online – 33 – JANUARY 2011 watch as the rules for writing are applied to a fun topic – eating ice cream. To help students further develop their writing and editing skills, try a “write, pair, share” which is a version of a “think, pair, share” reading comprehension strategy. After students have finished their writing assignment, ask them to choose a partner to share with. Allow time for student pairs to “share” their writing, and then direct students to read and edit their partner’s work. Consider including this activity in a new writing center that also promotes listening and speaking.

For the Birds Geri Ruane Name __________________________________ As we ease back in to school, take a moment to consider a rather unknown holiday. National Bird Day, which takes place on January 5th. This holiday, established by bird activists, is to draw attention to the exploitation of pet birds and captive birds. Why do we have such a holiday? According to the Born USA Web site, “… nearly twelve percent of the world’s 9,800 bird species may face extinction within the next century.” One of the goals of National Bird Day is to educate the public about the plight of the world’s birds: both in captivity and in the wild. 3. Explain the focus of National Bird Day. 4. In this month’s Internet Challenge™, we will see the significance of encouraging the public to appreciate our own native birds as well as birds from other nations.

You have done a terrific job completing this month’s Internet Challenge™. ________ Learners Online – 37 – JANUARY 2011 Answers to January's Internet Challenge™ 1. (e) all of the above 2. Their existence is being threatened due to pressures from the illegal pet trade, disease and habitat loss. 3. National Bird Day is a day to take time to appreciate the native wild birds flying free outside. It is also a perfect time to reflect on how we treat the native birds of other countries. While we have enacted laws to protect our native birds — such as blue jays, cardinals, and crows — from commercial exploitation, we fail to recognize the inconsistency in allowing the pet industry to exploit the birds of other countries. 4. Each year thousands of birds are sold into the pet trade to individuals who are under the mistaken impression that a bird will make a perfect pet. Whether due to frustration, disinterest, or concern, many people attempt to rid themselves of the responsibility of caring for their birds. Few of these birds will find a good home, and most will spend their days confined and isolated in their cages. Others will be bounced around from caretaker to caretaker and some may be abandoned at local shelters and bird rescue groups, set free to take care of themselves or to be euthanized. 5. Students’ own answers. Some suggestions: Give birds (a) a healthy diet that would include not just seeds, but grains, beans, vegetables (cooked and raw) formulated pellets, and some fruit; (b) plenty of daily exercise and out-of cage time; (c) socialization with other birds or humans; (d) teaching your bird new tricks or games. 6. A bird owner should use a clean spray bottle of water to promote feather and skin health and for fun. Some birds prefer to bathe in a small container (like their water dish); others enjoy being misted with water. It is important to allow the birds to air-dry in a warm room or in the sunshine. 7. Parrots are very intelligent and social; they have been compared to human toddlers in the needs of their emotional and social lives. However, unlike children, they never grow up. 8. Students’ own opinions. 9. The author advises the reader to be wary of rescue organizations that will not accept smaller birds. They may simply be looking to acquire larger birds to sell or adopt out at higher fees. 10. (b) false 11. The stress of confinement can lead birds to show abnormal behaviors, such as excessive screaming, feather plucking, self-mutilation, and other destructive habits. 12 This investigation exposed an alarming level of mistreatment of animals, particularly birds. It documented neglect of birds in the pet stores, from overcrowding and unsanitary housing to severe injury and illness. 13. In an effort to protect parrots in the retail pet industry, API and the AWC introduced California Assembly Bill 202, which would require that parrots are able to eat on their own ("weaned") before they are released from a pet shop. It also would require that pet shops must have one to two employees trained in the care and feeding of young birds. The bill went into effect on September 1, 2004, making California the first state in the nation to regulate the sale of unweaned birds. Some stores in the pet industry oppose this. 14. Students’ own answers. 15. Animal hoarders often masquerade as “rescuers,” describing their homes as “shelters” or “refuges.” But hoarding is not about legitimate animal sheltering or rescue; it is a serious mental illness that jeopardizes the health and welfare of the animals and the people involved. The medical profession now recognizes animal hoarding as a psychiatric disease that is closely related to obsessive-compulsive disorder. 16. (a) Regulations for an animal sanctuary: No breeding or commercial trade; no invasive or intrusive research; no unescorted public visitation or contact in wild animal sanctuaries; and no removal of wild animals for exhibition, education or research. (b) Students’ own answers. Extension Activities – students own answers. ________ Learners Online – 38 – JANUARY 2011 Estimated Time: 30 Minutes Blizzard J. Alan Baumgarten On December 26, 2010, the first major blizzard of winter slammed the northeastern United States. The storm unleashed powerful winds as it moved up the coast, dumping a foot of sideways-blowing snow on some areas with more expected through Monday’s morning commute. G overnors declared states of emergency in Virginia, Maryland and Massachusetts ahead of the approaching storm, a bid to get crews ready and expedite recovery funding depending on its impact. The mayors of Philadelphia, Boston, Providence and Portland, Maine, also called snow emergencies, while New York City launched a winter snow storm operation and encouraged people to stay off the roads by taking mass transit or staying put. TEKS §112.18. Science, Grade 6 (9) Force, motion, and energy. The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form. The student is expected to: (A) investigate methods of thermal energy transfer, including conduction, convection, and radiation; (B) verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting In this week’s online activity, get ready to learn cool facts about snowflakes and snowstorms. All About Snow Our first stop this week is All About Snow, a section of the Education Center at the National Snow and Ice Data Center. Here you can study snow in a variety of different contexts, including science, geography, and history. Read the overview, and then click Q&A.

We certainly could not cover this pertinent topic without an unbiased examination of the views for why this application may or may not be ideal for education. S tudents attend school to gain information. That has been the backbone of our education system throughout history. Nowadays the way that students find out about, share and discuss, and ultimately disseminate and apply the information they learn is just as important as learning the information itself. We are in the very belly of the Web 2.0 ‘beast’ and depending upon the various perspectives, this may or may not actually be such an impenetrable monster. The debate about when and how schools should embrace and utilize Web 2.0 technologies is a relevant and important controversy to explore and discuss now. The various Web 2.0 applications that utilize social networking ideology is a ubiquitous component of most students’ lives. We as teachers also turn to the Internet as a tool for creating, searching, organizing, storing, collaborating, and sharing. And so we must assume that students are certainly not only following suit, but setting the pace. Therefore the debate is thus: Should Web 2.0 types of applications be implemented in the classroom and to what level is it legitimate and appropriate? The Views Let’s start with a couple of video clips of Mediated Cultures (from Digital Ethnography at Kansas State University). Scroll down and watch “The Machine is Us/ing Us.” Then scroll down further and watch “A Vision of Students Today.” This is the perspective of cultural ________ Learners Online – 42 – JANUARY 2011 anthropologist, Dr. Michael Wesch who studies the effects of innovative media on culture and society. After watching these clips, take a moment to jot down the ways you currently use Web 2.0 programs. Consider which of these students might also be using. Next to each item that you listed, write down one positive outcome and one negative concern that you or other parents/teachers may perceive. For an excellent entry point into this debate, read the statements defending and opposing the motion as set forth in The Economist 2008 debate, “This house believes social networking technologies will bring large [positive] changes to educational methods, in and out of the classroom.” As you consider the proposing and opposing views, think of your own classroom environment. What would be the pros and cons of implementing various forms of this type of learning through technology with your group of students? Since there is such a vast range of opinions on implementing Web 2.0 technologies in the education realm, the best way to stay informed is to read the information generated by various sources. Staying informed and considering the pros and cons is the best way to enter the debate with a substantial base of information. Consider reading any of the following articles: • Brave New Classroom 2.0 from Britannica Online • Foundations of Educational and Instructional Assessment / Technology / Web 2.0 by Darby Christian • Web 2.0 in the Classroom Meeting Learners in their World by Ryan McCallum • Survey shows barriers to Web 2.0 in schools from eSchool News. The Good, the Bad, and the Technology Next, try this activity. Make a classic two column table on a sheet of paper. Consider working on this with another colleague or even a parent. Write ‘Pros’ at the top of one side and ‘Cons’ at the top of the other. Generate your own list of potential positive and negative issues with Web 2.0. In the meantime, here are ________ Learners Online – 43 – JANUARY 2011 some general suggestions as collected from a variety of online blogs: Pros: • more opportunity for cross referencing information increased amount of perspectives and therefore discussion on a particular topic • greater access to creative/innovative ideas to build upon allows students to employ strategies of skepticism in considering data online • helps parents to stay in touch with how their children communicate and what they view on online • exhibits to parents and teachers how students learn as opposed to just what they did that day; explores the process that students employ to learn rather than only seeing the final product or finished test or quiz • learning occurs inside and outside of school; therefore preparing students to use the available tools that will help them to continue to absorb data and apply skills beyond the classroom is essential to lifelong success • access to enhanced opportunities for diversity and exploration of other cultural realms. Cons: • students easily swayed off topic • distraction by off-topic content leads to wasted time • access to plethora of ideas makes students ‘lazy’; less likely to access their own imaginations • some students might take data shared in 2.0 environments at face value and come away with misinformation • substitute for face-to-face interaction; negative affect on real world social development • social networking is distracting; ads are hurled at students and teachers everywhere • learning objectives are blurred due to lack of a set structure which is found in a traditional classroom • potential for privacy invasion • potential for online bullying/harassment. ________ Learners Online – 44 – JANUARY 2011 Join the Debate Go ahead; join this debate. Your views and experiences are very important. No matter what your perspective is about implementing the Web 2.0 technologies, it is real and it counts, and it should be considered. Steve Hargadon hosts the Web 2.0 is the Future of Education blog that you might find interesting. Classroo m 2.0 is a vast resource that focuses specifically on this issue. Explore this source and join in the ongoing conversation here as well. Web 2.0 technologies are a very present component of the digital world we all exist in today. In fact, whether realized and accepted or not, the social networking applications have already begun to transform how we implement curriculum, how we disseminate instruction, and how learners receive and compute the information. This debate is by no means ‘resolved’ and continues to be a hot topic at the forefront of administrations’ agendas all over the country (and world for that matter). However, the bottom line is that we have 75.2 million 21st century learners in the United States (population of children ages 0 to 17 as of 2010 according to the U.S. Census Bureau). This group of the population will need the tools to be able to lead our country in the global forum. We will ultimately need to make a decision about what skills are important for their universal success.
