| Abstract: | Improving the algebraic concepts and skills of secondary school students with learning disabilities is critical for their success in college and in the job market. This research reviewed 12 studies to examine interventions for students with learning disabilities in relation to algebraic notions and competencies. The results indicate that in regard to the Common Core State Standards for Mathematics (CCSSM) Content Standards, the majority of the studies address linear equations and expressions, linear inequalities, and quadratic expressions; they show that following interventions, students’ performance improved with respect to algebraic concepts and skills. The Tau-U and Hedges’ g of the intervention effects computed were typically large or very large. The most commonly used instructional components in the interventions were multiple representations, a sequence and/or range of examples, and explicit instruction. Limitations and suggestions for future research are discussed. |
