Abstract

The Covid-19 epidemic that occurred in 2019 prevented education from continuing face to face. Various searches were conducted as part of this procedure that can be used effectively in online education. As a result, the GeoHepta mobile application was created to help students study the 7th grade mathematics course subjects using the ADDIE design methodology. Activities using dynamic mathematics software that students may use interactively were created as part of the content of the built mobile application. Students were also given the opportunity to complete online evaluation using Web 2.0 tools after learning the lesson's topics. The research was performed by 7th-grade students in a secondary school in the Central Anatolia Region in the second term of the 2020-2021 academic year, utilizing a mobile application in the distance education process. A quasi-experimental design was used to conduct the study. The “Mobile Application Usability Scale” was involved in the analysis to assess the usability of the mobile application after the experimental group had been educated. As a result of the research, it was established that the GeoHepta mobile application is "usable" by the students, and their attitudes about the mobile application are good. Participants' opinions on the mobile application's style, colour, control, typeface and hierarchy are also "useful". The "control" function of the mobile application received the greatest score, while the "aesthetic" aspect of the mobile application received the lowest grade.

Keywords
