This study explored the lexical coverage of corpus-based vocabulary lists (general, academic, and content-specific) across several million tokens gathered from digital science resources (DSR) for middle school (6-8 grade) students in the United States. The goal was to estimate the extent to which a combination of well-known word lists, mostly…

This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

Graded readers are a great asset to learners acquiring the vocabulary of another language. Homonyms, on the other hand, are a recognized source of trouble for students with that same goal. Publishers of graded readers control the presentation of old and new words, but does this control extend to homonyms? Are only the word forms controlled for--in…

Several researchers have claimed that low-achieving students, especially second language students, need explicit academic vocabulary instruction to "catch up" with their age peers (e.g., Nagy & Townsend, 2012). Two possible paths to vocabulary growth -- free reading and explicit vocabulary instruction -- were compared in terms of…

Studies of lexical coverage are valuable because they reveal the importance of vocabulary knowledge to comprehension. Lexical profiling research is also extremely useful because it indicates the vocabulary knowledge necessary to understand different text types such as novels, newspapers, academic lectures, television programs, and movies.…

This paper aims to be an introduction to the General Service List (GSL) that brings together descriptive data with material otherwise dispersed throughout the literature. The discussion first provides an historical overview of the work that scholars, researchers, and educators used as foundations for the manufacturing of the GSL. Following, a…

A statistical study of 100,000 words from medical English literature to determine the core lexis of medicine across specialties is reported. It is suggested that both the research procedure and the results are applicable to instruction in reading medical English for professional purposes. (MSE)

Subtechnical vocabulary includes items that are neither highly technical nor obviously general, and rhetorical/organizational items are in this category. They serve to signal the writer's intentions or his/her evaluation of the material presented. A technique for identifying subtechnical items is explained. Three identified items are analyzed, and…

Describes a self-instruction procedure designed to provide students of science and technology at the tertiary level with a basic vocabulary in a foreign language of around 1,000 items. The technique represents an efficient method for bridging the gap between the vocabulary that beginning L2 students possess and that required to read L2 scientific…
