The purpose of this study was using schematic video to help hearing-impaired students solve multi-step arithmetic word problems involving money. The participants were 4 hearing-impaired students: two 4th graders and two 3rd graders. The single subject multiple-probe design across students was employed with 4 phases: base, intervention, maintenance and transfer. Paper and pencil tests were used in base and transfer phases, and computer tests were used in intervention and maintenance tests. The students were found to be interested in the schematic video software and the schemas help them to think and solve multi-step arithmetic word problems.
