Improving vocabulary and reading comprehension is critical to students' academic success, particularly for English learners who may have less exposure to academic language than native English-speaking students. "Word Generation" is a supplemental program that aims to improve students' reading comprehension by building students' vocabulary, academic language, and perspective-taking skills through classroom discussion and debate. "Word Generation" was designed for all students; however, English learners in particular could benefit from its focus on academic language. This What Works Clearinghouse (WWC) report, part of the WWC's English Learners topic area, explores the effects of "Word Generation" on English language proficiency and reading comprehension for English learners. The WWC identified nine studies of "Word Generation" that focused on English learners. One of these studies meets WWC standards. The evidence presented in this report is from one study of the impact of Word Generation on English learners in a range of grades--4th through 7th--and in a variety of school settings, including elementary, middle, and K-8 schools in urban, suburban, and small town districts. This intervention brief provides an overview of the full report. [For the full report, see ED604123. For the Intervention Snapshot, see ED604125.]
