The Role of Vocabulary Instruction in Adult Basic Education
Vocabulary has long been recognized as a key factor in reading comprehension. In this chapter, Curtis analyzes research and theories on vocabulary, vocabulary acquisition, and reading comprehension. She presents approaches to vocabulary instruction that have been proven effective and also makes recommendations for practice, research, and policy.
Curtis begins by describing four hypothesis that attempt to explain the relationship between vocabulary and reading comprehension: instrumental hypothesis, byproduct hypothesis, knowledge hypothesis, and language proficiency hypothesis. In the next section she discusses ways vocabulary might be learned - contextual analysis, morphological knowledge, and definitional skill. - and the nature of vocabulary - its breadth and depth. Next, Curtis explains effective approaches for teaching vocabulary. Due to a lack of research with adults, Curtis uses the research with children. This research shows that direct instruction, differentiation of word meanings, promotion of word consciousness, and engagement in wide reading are useful instructional approaches. Curtis ends the chapter by making recommendations for research, policy, and practice.
This chapter is important for researchers, graduate students, and adult literacy educators who are interested in the role of vocabulary instruction in ABE. It does not provide teachers with many "how to" strategies, but it does provide them with a strong understanding and rationale of why vocabulary instruction is important and how it is related to reading growth.
Curtis is a recognized expert on the topic of vocabulary instruction. She is the logical person to write a review of research such as this. She has selected appropriate research to include, and she has organized the review in a logical, approachable manner. Her clear writing style should be accessible by just about anyone working in the adult education field.
