Özet:

The education system is continually developing through the integration of technology into education and the development of new instructional models. Both the instructional models which require technology usage and the presentation of evidence-based models with technology are tested for their effectiveness in the education of students with normal development, as well as for students with intellectual disabilities. Direct Instructional Model is one of the evidence-based instructional methods which is used for the teaching of concepts and skills in special education. The aim of this current study is to develop a technology-based material for concept teaching with the Direct Instruction Model and to examine the contribution of this material on 3-dimensional (3D) cube, cylinder, and cone geometrical shapes acquisition of students with mild intellectual disabilities. Another purpose of the study is to examine the contribution of this material on retention rates of labeling skills of students on newly learned shapes and retention rates of students in the generalization of these newly learned shapes to different contexts in the 3rd, 4th, and 5th weeks after training. Also this study is purposed to check out the social validity of this technology-based material. Multiple probe design across behaviors is used as single-subject research methods in this study. Four students with mild intellectual disabilities, three teachers of these students and six special education experts form the group of participants of the study. Results showed that Shape Finder application have contribution to cube, cylinder and cone shapes acquisition of students with ID and retention of these newly learned shapes in the 3rd, 4th, and 5th weeks after training. The students can generalize the learned shapes to real objects. Also according to interviews with students, teachers and experts, the Shape Finder application is found socially valid.
