The Value of Direct and Systematic Vocabulary Instruction
PROFESSIONAL DEVELOPMENT SERIES Volume 7 The Value of Direct and Systematic Vocabulary Instruction by Jerome Shostak A lthough independent reading plays a critical role in the acquisition of new vocabulary, the vocabulary growth needed for successful reading comprehension should be the result of systematic, direct instruction, and not left to incidental learning alone. Teachers can encourage and facilitate vocabulary acquisition by helping students learn strategies for determining the meaning of words independently, by teaching specific words directly, and by playing an active, directed role in the process. According to its assessment of the research literature on reading instruction, the National Reading Panel has affirmed that the most effective teaching does not depend on a single vocabulary instruction method (Report of the National Reading Panel, April, 2000). Instead, the teaching of vocabulary should be systematic, repetitive, and eclectic. In introducing new words, teachers should be guided by three principles that Stahl (1986) recommends and that other research supports: (1) use both a definitional and a contextual approach, (2) strive for "deep processing," and (3) provide multiple exposures (Baumann and Kameenui, 1991). SADLIER-OXFORD Professional Development Series new meaning (Nagy, 1988) and making the word both "more explicit and employable" and fully conceptualized (Baker, Simmons, and Kameenui, 1995a). It means, according to Baumann and Kameenui (1991), being able to identify a synonym for a word, to generate an oral definition, to place a word within a semantic category, to discriminate between a word’s denotative and connotative meanings, to express the obvious and subtle differences in meanings among a set of synonyms, and to use a word sensibly in an oral or written context. How Do Students Learn New Words? We know that students in grades 3 through 12 are likely to learn about 3000 new words each year (Nagy and Anderson, 1984; Nagy and Herman, 1987). And, as Nagy, Herman, and Anderson (1985) point out, this "massive vocabulary growth seems to occur without much help from teachers." In other words, students acquire new vocabulary incidentally and from several sources. They learn new words from talking to friends and family members, from listening to CDs and to the radio, from watching movies and television programs, and, most importantly, from their reading. In fact, research shows that reading is the single most significant factor in the acquisition of new vocabulary (Anderson and Nagy, 1991; Baumann and Kameenui, 1991). But independent reading alone is not enough to provide the kind of vocabulary growth and development students need not only to be able to communicate successfully, but also to succeed academically and to perform well on standardized tests. According to Chaffin (1997) and Zechmeister, Chronis, Cull, D’Anna, and Healy (1995), research has shown that although reading is essential for vocabulary growth and development, it is not sufficient for most students because the meanings they take away from their readings will not be deep and enduring; nor does it help them gain strategies for becoming independent word learners. Researchers agree that although reading is indeed important, to achieve deeper, richer levels of lasting vocabulary understanding, direct instruction is more effective and more efficient than incidental learning (McKeown and Beck, 1988). Planned vocabulary instruction in specific words is what is needed, including specialized vocabulary instruction in the content areas (Baker, Simmons, and Kameenui, 1995b). Research tells us that for students who are well past the beginning stages of reading, learning new words fully and deeply means much more than simply recognizing those that are already part of their oral vocabulary. For these students, learning a word means acquiring a 2 SADLIER-OXFORD Professional Development Series (Nagy, 1988). Nagy goes on to explain that although definitions can play a key role in vocabulary instruction, by themselves they tell little about how a word is actually used. He points out that given only a definition of a word, students may have difficulty using it meaningfully in a sentence. The definitional approach is effective only when a limited knowledge of new vocabulary is desired (Beck, McKeown and Omanson, 1987). What Kind of Direct Vocabulary Instruction Works Best? Traditional vocabulary teaching can be categorized as following two general approaches: definitional and contextual. Using the definitional method, teachers have students look up words in a dictionary, write down and/or memorize definitions, use the words in sentences, find synonyms, and then complete worksheets or take quizzes. There are some undeniable advantages to this approach. For one thing, from dictionary definitions students can gain a specific meaning of a word they come across in their reading. For another, they can gain key and interesting information about the history of the word. Thirdly, they can gain a better understanding of interrelated words in word families. And, in addition, by combing through dictionaries and all the information they provide, students can gain a better appreciation of language. Examine the entry to the right for the word allocate. It is not of the dictionary type, but has unmistakable advantages. The definition is brief and simple and designed for maximum usefulness. Its intent is to give students a good idea of what the word means without extensive detail or secondary connotations. Notice that the entry also includes the word’s part of speech, its pronunciation, an illustrative sentence providing a context that clarifies and exemplifies its meaning, and a list of synonyms and antonyms. Vocabulary Workshop ©2002, Level E (10) In the contextual approach, teachers ask students to infer the meaning of a word by scrutinizing semantic, syntactic cues in a sentence or group of words containing that word, or by examining typographic clues from charts, graphs, pictures and the like. This approach also can be useful, but it Although the definitional approach can be both useful and necessary, learning definitions alone can "lead to a relatively superficial level of word knowledge [and] does not reliably improve reading comprehension" 3 SADLIER-OXFORD Professional Development Series should be noted that context clues alone may provide only a partial meaning of a word and occasionally may even be misleading (Nagy, 1988; Beck, McKeown and McCaslin, 1983). One way, according to Stahl (1985, 1986) and others, to make the contextual approach more effective in helping the reader to understand the meaning of a new word is to imbed it within a rich context of supportive and indicative information. Both the definitional and contextual approaches fit in an effective vocabulary program (Stahl and Fairbanks, 1986). However, the approach to vocabulary instruction that researchers have identified as being the most successful in providing students with fuller, richer word knowledge and increasing their reading comprehension, is an eclectic, systematic one that not only involves both of these approaches, but also contains three distinct elements: integration, repetition, and meaningful use (Nagy, 1988). Look at the following contextual analysis activity for the previously introduced word sophomoric. In this completing-the-sentence activity, the student is asked to write the word that logically and meaningfully fits in a given sentence. Notice the clues given for choosing the right word and that the focus is on the literal meaning of the word. By integration, researchers mean that in order for learning to occur, new information must be integrated with and be built upon what the student already knows (Christen and Murphy, 1991). In other words, instruction should guide students to use words and ideas they already know to help them associate meaning with words they do not know. One teaching technique that supports this strategy of drawing on students’ prior knowledge is to have them complete a semantic map, a visual tool that helps to make relationships among words more clear. The one shown to the right is for the word adversary. Vocabulary Workshop ©2002, Level E (10) 4 Copyright © by William H. Sadlier, Inc.

SADLIER-OXFORD SEMANTIC MAP BLACKLINE MASTER SADLIER-OXFORD Professional Development Series choose, from among two or more taught meanings of a word, the only one that the specific context will reasonably allow. (Note that activities like this one give students practice in the kind of skill assessed in the critical reading section of the SAT I.) Repetition is a second key quality of instruction. Research shows that repeated encounters with new words are essential if vocabulary instruction is to have a measurable impact on reading comprehension (Stahl and Fairbanks, 1986; McKeown, Beck, Omanson and Pople, 1985). But how do you create an instructional program that provides multiple exposures, that is not dull, and that enriches students’ understanding of new vocabulary? For that, we turn to the third quality of a successful program. Instructional activities that focus on meaningful use stem from the idea that students will learn more when they are actively involved in the assignment and when the task is similar to one they would ordinarily encounter in the course of speaking, writing, and reading. Additionally—and what is perhaps more important—the research indicates that when students are called upon to process information more deeply, and to make inferences based on that information, they will be more likely to retain the information (Nagy, 1988). Teachers can use a number of instructional tasks that require students to process new words more thoroughly and to think critically about them. For example, choose-theright-word and sentence-completion activities need not include only those that involve literal or direct meanings of the words; they can also focus on sentences or passages in which the words covered are used in a more figurative, extended, or abstract way. Other activities, such as the one shown to the right, may challenge students to use their usagediscrimination and critical-thinking skills to Vocabulary Workshop ©2002, Level E (10) Similarly, synonym/antonym exercises need not only reinforce meanings; they can also provide students with further examples of usage and context. Word-association activities can both reinforce and extend meanings through examples, situations, and allusions. Finally, analogy activities provide a useful way of investigating and discussing relationships among meanings of words. They serve as a means of pinning 7 SADLIER-OXFORD Professional Development Series down the precise meanings of words and of correcting misconceptions or uncertainties about how these words are used. Analogies deserve special attention in that they provide an excellent means for testing and refining the critical-thinking skills needed for success on standardized tests and in college. Furthermore, words that receive the attention necessary to complete an analogy successfully are more likely to become part of the student’s active everyday vocabulary. derivatives of words they already know. Accordingly, effective vocabulary teaching should include direct instruction in prefixes, suffixes, and roots. The following activity is an example of one that practices the strategy of focusing on morphemic elements. Using the previously introduced word demise, it introduces students to English words derived from common Latin stems mis, miss, mit—to send. In short, successful vocabulary teaching calls for a multi-faceted approach featuring both definitional and contextual instruction. That instruction should be supported by and include a variety of activities that provide multiple exposures of and practice with the new words in a meaningful way and in a way that draws upon students’ prior knowledge and upon what they may already know about the word. But there is still more that a teacher can do to provide a comprehensive approach to vocabulary acquisition. What Other Components Enrich Vocabulary Instruction? Another important way to learn new vocabulary is to use morphological knowledge. This is a key strategy that focuses on the structure of a word, its parts. These parts, called morphemes, include prefixes, suffixes, and roots. According to Aronoff (1994), new vocabulary acquisition can be facilitated for middle school and high school students with a good understanding of word structure, because many of the new words they are likely to come across in their reading will be Vocabulary Workshop ©2002, Level E (10) A good understanding of morphology, together with an ability to use definitional and contextual clues, provides a powerful combination that will help students uncover the precise meaning of words they 8 SADLIER-OXFORD Professional Development Series encounter in direct instruction or in their reading. A firm command of morphology helps students become not only better readers but better writers, too. It also helps them to use words sensibly when speaking. independent vocabulary acquisition. Focus instruction both on "specific words and transferable and generalizable strategies" (Baumann and Kameenui, 1991). • Foster an environment that promotes word play and a genuine interest in and enthusiasm for words; encourage students to share new words learned inside and outside of school. What Is the Role of the Teacher in Vocabulary Instruction? It’s critical. In her book The Academic Achievement Challenge: What Really Works in the Classroom, Jeanne Chall (2000) argues for the importance of the role that a teacher can play in promoting vocabulary development. She argues for a teacher-centered, curriculum-centered approach. • Guide students to use context clues and morphological clues like familiar prefixes, suffixes, and roots; and also encourage them to use the dictionary as a way to understand the precise meaning of words. Invite them to share findings about where words have come from and how they have evolved. There is much that teachers can do to enrich vocabulary instruction. Here are some useful classroom techniques: • Establish what students already know about a word through discussion; it is a powerful tool to "engage students in exploration and development of new word meanings" (Stahl and Vancil, 1986). • Establish vocabulary learning objectives for your students, including those that strive for 9 SADLIER-OXFORD Professional Development Series • Provide students with multiple opportunities and many different ways to demonstrate their knowledge of new words. For instance, do not hesitate to engage them in word games, board games, and puzzles. acquisition as assessed in first grade is a far better predictor than reading mechanics is of reading comprehension in grade 11. Having a strong vocabulary is of particular importance to students in that it contributes significantly to achievement both in the subjects of their school curriculum and also on standardized tests. When students combine their growing knowledge of word meanings with their increasing understanding of language structure and their developing knowledge of the world, they can flesh out strategies that help them make meaning of what they read in a variety of texts. Baker, Simmons, and Kameenui (1995b) have called a strong vocabulary "crucial to academic development." Increasing their word knowledge is a basic part of students’ learning process. • When students write, encourage them to use new words as frequently and as appropriately as possible. Discuss ways in which word choice affects their writing. • Have students keep notebooks in which they record interesting new words they have come across in their reading and through other avenues. • Frequently evaluate your vocabularylearning goals and the techniques and procedures you use; adjust your objectives as needed. • Lastly, be sure to provide extensive opportunities for reading; encourage independent reading as a regular part of every day, not only every school day. How important is vocabulary growth? Put simply, a strong vocabulary improves one’s ability to learn; a weak one hinders that ability. How Important Is Vocabulary Instruction? About the Author Word knowledge is essential to reading comprehension; several studies have shown this strong correlation, among them Baker et al. (1995) and Nagy (1998). In fact, research has shown conclusively that a reader’s vocabulary knowledge is the best indicator of how well that reader will understand what he or she reads (Anderson and Freebody, 1981). In his 1977 study, Becker showed the direct link between vocabulary deficiencies and academic achievement in his study of disadvantaged children in grades 3 through 12. Furthermore, Cunningham and Stanovich (1997) have reported that vocabulary Jerome Shostak was an English teacher for 37 years in the New York City public school system, where he also served as a grade adviser, college adviser, and certified guidance counselor. He was twice chosen Teacher of the Year. Mr. Shostak has been a lecturer in adult education programs for more than 25 years, as well as an instructor at Brooklyn College (NY) and at Palm Beach Community College (FL). In addition to the Vocabulary Workshop program, Mr. Shostak has also written a number of other books for Sadlier-Oxford and for other K-12 school publishers. 10 Allen, J. (1999). Words, Words, Words.
