Effect of manipulative-based interventions on improving mathematics computation outcomes for students with mathematics difficulties
In this report, we discussed the effect of manipulative-based interventions on improving mathematics computation outcomes for students with mathematics difficulties. We conducted systematic analysis on 23 articles including single case design studies, and group design studies by using random effect meta regression model. This study serves as the first study which combined single case design and group design studies in the data analysis in the field of manipulative-based interventions. We determined that the manipulative-based interventions are effective on improving whole number computation for students with mathematics difficulties. We also found that special education teacher or researcher implemented interventions had a larger effect size than that implemented by general education teachers. However, our conclusion should be considered as preliminary and more exploration on manipulative-based interventions are needed.
