The effects of computer aided concept teaching with direct instruction model on concept acquisition of students with intellectual disabilities

Tufan, Mehtap
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.

Caner, Sonay; Kaplan Akıllı, Göknur; Department of Computer Education and Instructional Technology (2015)
The enhancements of technology have profound effects on education. With the advent of Web 2.0 technologies into our lives, the conventional understanding of education has changed. One of the various uses of Web 2.0 in teaching and learning processes is digital artifact generation. This study has two aims: to investigate sophomore students’ level of learning through generating digital artifacts with Web 2.0 tools, namely, blog, concept map, and infographic based on Bloom’s Revised Taxonomy; and to investigat...
The role of space in interdisciplinary collaboration in design education
Kaygan, Pınar; Aydınoğlu, Arsev Umur (2018-09-01)
The growing interest in the collaborative design education for innovation has mainly been concerned with students and learning outcomes. We know less about the collaboration between the tutors who teach interdisciplinary design courses. Addressing this gap, this article explores the effect of space on the interdisciplinary collaboration between faculty members from the fields of industrial design, architecture, engineering and business administration, who come together to design and conduct an extra-curricu...
Development of a multi-dimensional model to evaluate higher education instructors’ adoption towards learning management system
Fındık, Duygu; Özkan Yıldırım, Sevgi; Department of Information Systems (2010)
Through the rapid expansion of information technologies, Learning Management Systems have become one of the most important innovations for delivery of education. Successful implementation and management of these systems are primarily based on the instructors' adoption. However, too few researches have been conducted to evaluate instructors’ adoption towards e-learning system as taking higher education as base. This study aims to understand behavioral intentions of higher education instructors towards Learni...
