This study evaluated the effectiveness of video modeling and prompting strategies on teaching weight measurement skills to three elementary students with intellectual and hearing disabilities. The intervention included a 3-min instructional video and task analysis, followed by group instruction. Students demonstrated clear improvements in skill acquisition and accuracy, with sustained results during the probe phase. Social validity evaluations indicated positive feedback from the teachers, supporting the practicality of the intervention. However, the limitations include a small sample size and the need for prerequisite skill assessments. This study demonstrates the feasibility of combining video modeling and prompting strategies to teach practical mathematics skills in special education settings.

Systematic instruction and video modeling are evidence-based practices for teaching academic skills to students with intellectual disabilities; however, its efficacy has not been established for teaching graphing skills in a small-group setting. Three elementary school students with hearing and intellectual disabilities were taught to describe graphs and compare their differences in a math class at a special needs school using systematic instruction and video modeling. The effectiveness was evaluated using a multiple-baseline across participants’ design. The results showed an increase in correct response rates after the intervention, with similar levels of correct response rates in the probe and graphing based on tables phases. A functional relation was demonstrated between systematic instruction and video modeling and graphing behaviors.
