Design of TePytha-App to Improve Mathematics Learning Achievement in Pythagorean Theorem Material

Abstract

Learning media is one of the factors in improving student achievement. For this reason, learning media need to be developed along with the development of technology according to the needs of students. The purpose of this research is to design an android-based learning media in the form of a learning application to improve students' learning achievement in mathematics. Sources of data in this study were class VIII SMP Negeri 1 Gamping, material expert validators, and media expert validators. The instruments used in this study are interview guidelines, observations, questionnaires, midterm assessment (PTS) test results, material expert validation instruments, and media expert validation instruments. The data analysis technique includes the stages of data presentation, data reduction, and concluding. The results in this study show that (1) students' mathematics learning achievement tends to be low. This can be seen from the average value of the Middle Semester Assessment (PTS) of students which is only 56.72 while the Minimum Completeness Criteria (KKM) is 75. So it is necessary to develop android-based learning media; (2) application development assisted by Microsoft PowerPoint, iSpring, Website 2 APK Builder, and Java; (3) TePytha application contains the features of the home page, main menu, competencies to be achieved, introduction to Pythagoras, material menu, learning videos, quizzes, and exercises; (4) the results of the validation of material experts and media experts indicate that the product is valid to use with an average category is good. The research will proceed to the implementation and evaluation stages.
