The purpose of this study was to further address the "for whom" in the question of the effectiveness of modified schema-based instruction (MSBI) to teach mathematical problem solving to students with intellectual and developmental disability by evaluating whether positive outcomes from prior research would be replicated with elementary…

Although solving word problems involves both literacy and mathematics skills, research to date has only targeted mathematical learning. This study sought to increase teaching efficiency by embedding literacy instruction within mathematical word problem solving instruction for three elementary students with intellectual and developmental…
