Purpose: Improving vocabulary knowledge is important for many adolescents, but there are few evidence-based vocabulary instruction programs available for high school students. The purpose of this article is to describe the iterative development of the DictionarySquared research platform, a web-based vocabulary program that provides individualized…

In this article, we focus on a series of lessons, called "Think Like a Linguist," that we designed and implemented with multilingual adolescents. These lessons were developed as an introduction to a semester-long study on academic vocabulary and word analysis using Latin roots. Our intention in "Think Like a Linguist" lessons…

Background: Morphological analysis skill is the ability to problem-solve meanings of unfamiliar words by applying knowledge of morphological constituents. For vocabulary words from the academic layer of English, the major, meaning-carrying morphological constituents are Latin roots (nov meaning 'new' in innovative). The degree to which…

This study investigated the hypothesis that academic vocabulary instruction infused with morphological analysis of bound Latin roots-such as analysis of the relation between innovative and its bound root, nov (meaning "new")-will enhance word learning outcomes for English Learner (EL) adolescents. Latinate words with bound roots comprise…

Given that words from the academic layer of English typically carry bound roots ("min" in "diminish") rather than free-standing base words ("small" in "smaller"), there is a need to understand the factors that make bound roots more or less accessible for morphological problem-solving unfamiliar words. We…

The purpose of this research is to develop a vocabulary assessment, Evaluation of Academic Vocabulary or "EAV," that gauges students' depth of knowledge of academic words and is sensitive to vocabulary growth in the context of literacy interventions. We report results from two studies with native English-speaking middle school students…

Purpose: In this clinical focus, the authors argue for robust vocabulary instruction with emergent bilingual learners both in inclusive classroom settings and in clinical settings for emergent bilinguals with language and literacy disorders. Robust vocabulary instruction focuses on high-utility academic words that carry abstract meanings and…

This article presents findings from an intervention across sixth and seventh grades to teach academic words to middle school students. The goals included investigating a progression of outcomes from word knowledge to comprehension and investigating the processes students use in establishing word meaning. Participants in Year 1 were two sixth-grade…

How can we supplement the limited time available for vocabulary instruction while motivating students to attend to the words they are learning? As a part of an academic word vocabulary intervention, we challenged sixth-grade students to find their words in the world around them. This activity, In the Media, garnered responses from 51 of the 61…

Examines the relative effectiveness of dictionary definitions and definitions revised to address problems found in traditional definitions. Finds that revised definitions led to significantly more responses that demonstrated a characteristic use of the word. Concludes that revised definitions were more effective in helping students understand…

Describes a study whose purpose was to identify the relative contribution of the nature of instruction and the frequency of encounters in bringing about word knowledge proficiency in fourth-grade children. Results suggest that instruction based on definitional associations is sufficient to affect word knowledge. (HOD)

The process of acquiring word meaning from context was investigated for high- and low-ability fifth-grade children. Findings demonstrated characteristics of processing that differentiate successful and less successful acquisition and underscore the complexity of the meaning-acquisition process. (HOD)
