Video Modeling and Systematic Instructions to Teach Graphing Skills to Elementary School Students With Intellectual and Hearing Disabilities

Abstract

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.
