This is revealed that the necessity of determining the computer assisted instruction to what extent affects students success. The purpose of this study is to examine the effect of computer-assisted geometry teaching on seventh grade students achievement. Its an experimental research in which pre and post tests are used. Data collected through 22-item geometry achievement test developed by researchers. In experimental group, the courses were taught by the help of Vitamin Program, recommended by Ministry of Education and Microsoft Picture Manager program in information and technology class at school. However; in control group, the method and activities included in the present programme are processed in their own classroom. The data were analyzed via SPSS 16 software, t-test and Ancova was conducted to analyze the data. As a result, this study showed that there is a positive effect of computer assisted instruction on the students geometry achievement. Based on this; it is seen that computers and educational software in teaching geometry have positive effect on students academic achievement.eninfo:eu-repo/semantics/closedAccessGeometry TeachingReflectionRotationComputer Assisted InstructionArticle211928WOS:000437446200002N/A
