    The Effects of Computer-Aided Concept Teaching With the Direct Instruction Model on Concept Acquisition of Students With Intellectual Disabilities
    (Routledge Journals, Taylor & Francis Ltd, 2025) Tufan, Mehtap; Yildirim, Soner; Altunay, Banu; Information Systems Engineering
    This study aimed to develop and evaluate a technology-based instructional tool using the Direct Instruction Model (DIM) for teaching geometric concepts - cube, cylinder and cone - to students with mild intellectual disabilities (ID). The 'Shape Finder' application was designed following DIM principles and assessed using a multiple probe design across participants. Four students with mild ID, their three teachers and six special education experts participated. Data collection involved app-based performance metrics, observations and interviews. Results indicated that the Shape Finder effectively supported students' acquisition, retention (up to five weeks), and generalisation of the targeted geometric shapes to real-world objects. Interviews confirmed the application's social validity. The findings highlight that integrating evidence-based instructional models with technology can enhance concept learning for students with mild ID, facilitating both short-term gains and long-term retention. This study underscores the potential of well-designed digital tools in special education to support conceptual understanding and generalisation across contexts.
