摘要:AbstractThe aim of this study is to develop suitable instruction materials for the computer enriched learning cycle model regarding the “pyramid” subject. For that purpose, work sheets related to the “pyramid” subject have been developed. The method of the special case study has been used in the study. The implementation of the study has been performed with 20 students who are studying in the 8thgrade of a school in order to use the instruction materials in a more efficient way and test the in-class applicability of these materials. Upon the performed implementation, it has been observed that the course has become more comprehensible for the students; the course attracted the interest of students; and the students have been able to associate a subject in the mathematics course with their daily life. Consequently, it can be stated that the use of suitable materials for the computer enriched learning cycle model in mathematics courses has been effective; and the views of students have positively changed for mathematics in general and for geometry in particular. In this sense, it is recommended that the materials, which have been developed in the scope of the study, be used in mathematics courses and similar materials also be developed for other subjects.
