A Review of Middle School Vocabulary Interventions: Five Research-Based Recommendations for Practice.

Purpose The purpose of this tutorial is to explain key concepts about vocabulary acquisition and instruction and to translate research from middle school vocabulary interventions into practice recommendations for practitioners. In this tutorial, we consider the relationship between vocabulary and reading comprehension, describe vocabulary acquisition including the development of semantic networks, provide a review of high-quality middle school vocabulary studies, and make recommendations for practice. Method We reviewed the experimental and quasi-experimental literature examining the impact of vocabulary instruction on the vocabulary and reading comprehension development of middle school students.
