Abstract

Word problem-solving is one major area in mathematics that has been identified as being particularly challenging for students, specifically for those with learning disabilities (LDs) and emotional and behavioral disorders (EBD). This study aims at evaluating the effects of a strategic math intervention with concept maps on the ability to solve word problems (addition and subtraction problems, number range of thousand) among students with LDs and EBD from the eighth grade. A multiple-baseline design across participants ( N = 9) was applied to evaluate the intervention, which was held three times a week over a 6-week period. Overall, the results demonstrated a functional relation between the amount of correctly solved word problem tasks and the intervention. All nine students improved in word problem-solving, as evidenced by the fact that more tasks were solved, with a higher score in the intervention phase compared with the baseline (between-case standardized mean difference was 1.84; 95% confidence interval [1.24, 2.44]). The social validity data display that all students found the intervention helpful but also partly exhausting. The limitations and implications of this study are discussed.
