The Pythagorean Academy Application—Design, Development, Implementation, and Evaluation of a Mobile Game for the Junior High School Geometry

ABSTRACT Educational mobile game applications can effectively support learning by offering engaging ways to present difficult concepts. This is especially beneficial for teaching secondary school Geometry, which many students find challenging. This paper introduces Pythagorean Academy , a mobile app aligned with the Greek junior high school curriculum. The app not only tests students' understanding but also provides corrective feedback and theory explanations—features uncommon in educational apps. It also accommodates students with visual impairments and learning disabilities, such as Attention Deficit Hyperactivity Disorder, through tailored visuals and audio support. Incorporating gamification elements, the app boosts motivation and promotes autonomous learning, making Geometry more accessible and enjoyable. Statistical methods, including the Mann–Whitney U ‐test and the Wilcoxon signed rank test, evaluate the app's effectiveness. This study demonstrates how integrating Geometry concepts into a gaming framework can leverage modern technology to improve Geometry education.
