I need some help in clearly understanding how to construct warm ups. ups. 2 Outline • Introduction • Just Just--inin-Time Teaching – “Theory” – Implementation – Aside: How to get great student evaluations • Assessment • Getting started 3 When you plan to teach a course what influences your thinking? • #1 Experience as a student • #2 Discussions with colleagues. colleagues • Some PER, publisher materials, other 4 Examples p • oropendola oropendola:: I try to remember what topics were difficult for me to learn… learn • Michael: My experience as a student is useful for me to measure the minimum coverage… coverage • Marco: …I discuss the [book] selection process with ith the th previous i instructor. i t t So S after ft reviewing what material is expected to be covered by the University i look at the previously selected text… • Commonalities? Problems? 5 Counterexamples • snipe: Recently I have been trying to introduce into my classes, various techniques I have read about b t in i the th PER literature. lit t … • physics 113: I am amazed that "interaction with students" is not on the list--list---whether whether from graduate, undergraduate, or as a professor. Most of what I learn about how to teach is from my students.. students 6 Problem: • Classes designed for professors or “pre “pre--professors” • Students do not learn like we do – Not motivated i d to be b experts – Need more time to think – Not N t as goodd att working ki alone l – Not as good at judging their own performance – Many Man under nder greater pressure press re • Interesting work by Richard Felder (NCSU, Chem Eng.) Eng ) 7 Digression g • Could have spent time “collecting data” data” • Instead, spent time discussing it • Same content covered at greater depth 8 Outline • Introduction • Just Just--inin-Time Teaching – Background – Implementation – Aside: How to get great student evaluations • Assessment • Getting started 9 The “theoretical theoretical”” background g • • • • • Active learning (students think in class) Student centered (it is not about you) Formative assessment (real (real--time feedback) Peer interaction (learning and motivation) Many learning styles (faculty not like students)) students 10 JiTT ((and other active learning) g) • Proven effective for “regular” students and excellent ones – Anyone not a likely future professor • Used extensively at MIT MIT, RPI, RPI Harvard, Harvard Univ. of Illinois, other research universities • Also many small colleges (prestigious and not), not ), Community Colleges, high schools • Introductory, Introductory upper division, division graduate • ADAPT! 11 What is JiTT? JiTT? • Cello Cello:: Method to make class more responsive to students needs, and to encourage students to be better preparedd for f class, l via i prepre-class l assignments i t • Oliver Oliver:: Having the students interact with the course material you will be covering, covering and answer questions based upon that material well before class begins. • Bob: Enhancing the learning experience for students by engaging them in exercises that require them to think before enteringg the classroom. • Dr. B. JiTT is a feedback loop … The goal is to maximize student engagement g g and learning g during ga face--to face to--face class meeting. 12 Just--in Just in--Time Teachingg ((JiTT)) World Wide Web Homework Classroom Assignment Design 13 Just--in Just in--Time Teachingg • Adaptable • Combines C i “high “ i tech”” with i “high “ i touch”” • WarmUp Exercises = Online, prepre-class reading quiz: i – Due few hours before class – A few f openopen-ended d d conceptuall questions i – Cover that day day’’s material 14 Another Digression g • JiTT described in your words • Jargon already familiar (JiTT, WarmUp) WarmUp) • “preview preview”” of important concepts 15 The “Interactive Lecture” Lecture” • Step 1: Synchronization Read (some of) the students students’’ responses… responses What do they understand? • Step 2: Preparation Select excerpts from students work, adjust clicker questions, questions etc. etc • Step 3: Execution Class is a dialog based on student excerpts and faculty notes 16 Example p • Question: Is it possible to add heat to an ideal gas without changing its temperature? If it is possible, please l explain l i how h it i is i done. d – “It is not possible because the internal energy of an ideal gas only depends on the temperature temperature.... the internal energy will increase when the temperature rises.…”” rises.… – “It is i possible ibl to t add dd heat h t to t an ideal id l gas without ith t it changing it's temperature by the gas receiving the heat, and the atoms of that gas getting excited enough to di disperse that h heat h as fast f as they h receive i it…” it… i ” – “If you add heat to a system while the system is doing the corresponding p g amount of work, the temperature p will not change.” change.” 17 Choosingg and using g student responses p • Always say something positive – This Thi is i true, t but b t what h t if something thi else l occurs simultaneously… – This makes sense, but something is missing… – This is a great response… how would we know how much heat to add? • More useful phrases… – This is a good answer, answer but to a different question… question – This has a great beginning, but more could be added… – This is correct, but the reasoning isn’ isn’t quite right… 18 Tips p and Pitfalls • Explain methods and purpose on first day • No need to review all responses before class; sample for “useful useful”” quotes, grade later g , too,, not just j • Focus on students strengths, misconceptions and other problems. • Use answers from many students: not favorites. • Do not “isolate isolate”” WarmUps - scaffold lecture • Must be routine. Do not start/stop during semester • Upper level students can handle more “exploratory exploratory”” questions, connections to intro. 19 What makes a ggood WarmUp? p • king: A good "warmup "warmup exercise" lets a student motivate and think for the upcoming lecture on that topic. It is like the "spark"spark-plug" in a car. • JD: …One One that connects directly to the main goals, new notations, and possible missconceptions in the upcoming material • Tycho Tycho:… :… those that test the student's understanding and those that stimulate class discussion and are typically more open ended. 20 Online archive of Warmup p exercises http://webphysics.iupui.edu/warmup/physics_ http://webphysics.iupui.edu/warmup/physics_ archi e html archive.html • • • • • • • • Introductory physics (2 semester sequence) sequence) Statistical/Thermal Statistical /Thermal Physics (2 sets) Intermediate Mechanics (2 sets) Quantum Mechanics Mathematical Methods Intermediate E&M (2 semester sequence) Introductory Astronomy Modern Physics (coming soon) 21 smartPhysics y http://www.smartphysics.com/smartphysics/d http://www.smartphysics.com/smartphysics/d efa lt asp efault.aspx • • • • • • • Calculus Calculus--based Mechanics, Mechanics, E&M Pre--lecture videos (~15min/class) Pre ( 15min/class) Small, paperback text Integrated homework, “c “checkpoints heckpoints” Authored at UIUC by Gladding, Stelzer Stelzer,, Selen Published by W.
