Teaching Addition to Students with Intellectual Disabilities: TouchMath Presented Through a Game

The aim of this study was to determine the effectiveness of the TouchMath technique presented through games in teaching addition to individuals with intellectual disabilities. Additionally, this study investigated whether students could maintain the skills they learned after 7, 21, and 35 days and whether they could generalize them across different individuals and settings. Three students with moderate intellectual disabilities were the participants of the study. This study was conducted using the multiple probe design across participants, which a single-subject research method. The dependent variable of the study was the capacity of the students to perform addition operations, while the independent variable was the teaching process using the TouchMath technique presented through a game. The results of the study indicated that the teaching process was effective, permanent, and generalizable. Additionally, the social validity data showed that teachers had positive views on teaching with this technique.
