The goal of this experimental intervention study was to determine if evidence-based instructional strategies for general vocabulary words are effective with middle school English learner (EL) students and academic vocabulary words. Participants showed significantly more growth in their knowledge of academic vocabulary during the treatment condition than during the control condition. A secondary goal of this study was to examine the predictive utility of students' English language proficiency, and students' general vocabulary knowledge in English was a positive predictor for their academic vocabulary growth during the intervention. However, participants' growth during the control period had the greatest predictive utility for their growth during the intervention. Furthermore, this relationship was negative, suggesting that the intervention had the greatest benefits for students who made the least progress in English vocabulary in the absence of the intervention. Implications for instruction, policy, and future research are presented.
This study reports year 1 findings from a multi-site cluster randomized controlled trial of a cognitive strategies approach to teaching text-based analytical writing for mainstreamed Latino English Language learners (ELLs) in 9 middle schools and 6 high schools. 103 English teachers were stratified by school and grade and then randomly assigned to the Pathway Project professional development intervention or control group. The Pathway Project trains teachers to use a pretest on-demand writing assessment to improve text-based analytical writing instruction for mainstreamed Latino ELLs who are able to participate in regular English classes. The intervention draws on well documented instructional frameworks for teaching mainstreamed ELLs. Such frameworks emphasize the merits of a cognitive strategies approach that supports these learners' English language development. Pathway teachers participated in 46 hours of training and learned how to apply cognitive strategies by using an on-demand writing assessment to help students understand, interpret, and write analytical essays about literature. Multilevel models revealed significant effects on an on-demand writing assessment (d = .35) and the California Standards Test in English Language Arts (d = .07).
In this study, 72 secondary English teachers from the Santa Ana Unified School District were randomly assigned to participate in the Pathway Project, a cognitive strategies approach to teaching interpretive reading and analytical writing, or to a control condition involving typical district training focusing on teaching content from the textbook. Pathway teachers learned how to use an on-demand writing assessment to help mainstreamed English learners understand, interpret, and write analytical essays. In Year 2, treatment effects were replicated on an on-demand writing assessment (d = .67) and showed evidence of transfer to improved performance on a standardized writing test (d = .10). The results underscore the efficacy of a cognitive strategies reading/writing intervention for mainstreamed English learners (ELs) in the secondary grades.
