Brief 1 - July 2016 - Vocabulary Learning to Enhance Reading for Understanding

Sep 28, 2026

Brief 1 (July 2016) examines how vocabulary knowledge drives reading comprehension beyond basic word recognition. It defines vocabulary as receptive and expressive language understanding, explains degrees and types of word knowledge, and clarifies what it means to “know a word.” The brief connects vocabulary to deep comprehension processes and describes what happens when learners lack relevant word and background knowledge, outlining why vocabulary instruction matters for struggling readers through research and classroom examples.

Brief 1 • July 2016 Vocabulary Learning to Enhance Reading for Understanding Nonie K. Lesaux, Ph. D., and Julie Russ Harris, Ed. M. Harvard Graduate School of Education Introduction The relationship between vocabulary and reading is not always an obvious one, especially when we think about how important it is that our learners be able to read the words on the page—with accuracy and efficiency. It’s true that we absolutely need to support students to develop strong word-reading skills, but for many students, thinking of these skills as the “gateway” to deep comprehension is where the logic breaks down. Why? Well, while reading words are necessary for even getting to comprehension, the real comprehension processes are about connecting the words we read to the concepts and ideas that those words represent. In this brief, we focus on the vocabulary side of “reading”—how our learners’ understanding of the vocabulary that fills the printed page or screen is ultimately a linchpin for their reading comprehension. First, we describe what vocabulary is and its role in deep comprehension—why and how it matters greatly for all students. Next, we highlight the research on vocabulary instruction for struggling readers. We then provide classroom-specific examples of vocabulary instruction. What It Is Vocabulary knowledge is a key part of language development—it involves understanding the meanings of words and phrases heard or read (receptive vocabulary) and also using those words and phrases to communicate effectively in speech or writing (expressive vocabulary) . What Does It Mean to Know a Word? Degrees of word knowledge. As illustrated in Figure 1, knowledge of a word is not all or nothing—vocabulary knowledge exists in degrees, such that any learner has a particular “level” of knowledge of any given word (Beck, McKeown, & Kucan 2013) . When a learner has shallow knowledge of a word, she might only understand it when another speaker uses it as part of a story or set of directions—with knowledge of the words around it and some knowledge of the word, she is okay. However, she is not likely to use this word in her own speech or writing. When a learner has deep knowledge of a word, she has a rich understanding of what it means, how it relates to other words, and how it is useful in multiple contexts. She is very likely to use it in her own speech and writing. Vocabulary Learning to Enhance Reading for Understanding ‖ 2 Figure 1. Five Levels of Word Knowledge No knowledge General sense Narrow, context-bound knowledge Enough knowledge to understand but not enough to recall and use appropriately Rich, decontextualized knowledge of a word’s meaning, its relationship to other words, metaphorical use (Adapted from Beck, McKeown, & Kucan, 2013) Types of words. In addition to the concept of degrees of vocabulary knowledge, it’s important to know that there are also types of words to be learned. One way to think about word types is to categorize them on a continuum, from everyday words to academic words. Everyday words are those that we commonly use in social conversation, from pronouns (e. g., I, she) to high-frequency nouns (e. g., home, movie, dinner) to the action words we use to describe parts of daily life (e. g., cooking, watching, playing) . On the other end of the continuum are academic words. These words are used primarily in school, civic, and professional settings. They include general academic vocabulary words that are used across many content areas (e. g., research, exhibit, investigate) as well as content-specific academic vocabulary words that are unique to a particular subject (e. g., fraction in math and chemical in science) . When it comes to comprehending school texts, deep knowledge of the academic words that fill these texts is a must. How It Relates to Reading We cannot separate complex ideas and relationships from the vocabulary words we use to describe them (Figure 2) . Language

FAQs

How does vocabulary knowledge affect reading comprehension?

Reading comprehension depends on connecting word meanings to the concepts those words represent. Without enough relevant vocabulary knowledge, deep comprehension becomes out of reach.

What are the degrees of word knowledge described in the brief?

Word knowledge ranges from no knowledge to general sense, narrow context-bound knowledge, enough knowledge to understand but not recall and use, and rich decontextualized understanding that supports use across contexts.

What types of words does the brief distinguish for learning?

It distinguishes everyday words from academic words, including general academic vocabulary used across many content areas and content-specific academic vocabulary tied to particular subjects.
