Amanda Inns and colleagues from Johns Hopkins Center for Research and Reform in Education have completed a research review on effective programmes for struggling readers in elementary (primary) schools. A total of 61 studies of 48 programmes met study inclusion standards. 84% were randomised experiments and 16% quasi-experiments. Results showed positive outcomes for one-to-one tutoring and were positive but not as large for one-to-small group tutoring. There were no differences in outcomes between teachers and teaching assistants as tutors. Whole-class approaches (mostly cooperative learning) and whole-school approaches incorporating tutoring obtained outcomes for struggling readers as large as those found for one-to-one tutoring, and benefitted many more pupils. Technology-supported adaptive instruction did not have positive outcomes, however. The article concludes that approaches mixing classroom and school improvements with tutoring for the most at-risk pupils have the greatest potential for the largest numbers of struggling readers.
