Schema-Based Strategy Instruction in Mathematics and the Word Problem-Solving Performance of a Student With Autism

Abstract

The purpose of this study was to provide preliminary results on the use of schema-based strategy instruction to teach addition and subtraction word problem solving to a fourth grade student with autism. The student was taught to use schematic diagrams to solve three types of addition and subtraction word problems. A multiple probes across behaviors single-case design was used, with solving each of the three problem types treated as a separate behavior. Interpretation of results indicated that the participant’s ability to solve all types of one-step addition and subtraction word problems improved following instruction. Improvement also generalized to problems with unknowns in the initial and medial position and was maintained over time.
