The Effect of Geometry Teaching Designed with the Developed Mobile Application on the Academic Achievement of the Students

Abstract

In order to ensure active participation of students in the lessons during distance education period, different learning tools were sought. For this purpose, within framework of the ADDIE design model, it was desired to develop a mobile application called GeoHepta to be used in learning the 7th grade mathematics course Geometry and Measurement learning field subjects. The study was carried out in the distance education process with 7th grade students in the 2020-2021 academic year. The research was carried out with a quasi-experimental design. In the study, "Geometry and Measurement Learning Field Achievement Test" was used. As a result of the research, a significant difference was reached between the post-test scores of the students in the experimental group, in which the mobile application-supported teaching was implemented, and the control group students, in which the textbook-based teaching was implemented. While there was a significant difference between the pre-test post-test scores of the experimental group students, there was no significant difference between the pre-test post-test scores of the control group students.
