Abstract

Mastering Maths is a mathematics learning application with mobile learning-based teaching materials that can assist teachers and students in doing distance learning. The purpose of this study was to develop an effective number pattern teaching material for improving the mathematical reasoning ability of junior high school students. This research method is R & D with ADDIE steps consisting of five stages, namely analysis, design, development, implementation, and evaluation. The subjects of this study were class VIII students in one of the public junior high schools in Bandung. The research instruments used were material and media expert validation sheets, student response questionnaires, interview sheets, observation sheets, and reasoning ability test questions. The data analysis technique used is triangulation to see the effectiveness of the teaching materials developed to improve students^ mathematical reasoning abilities. The results of the reasoning ability test were analyzed using the difference test of two averages with the help of SPSS 23. The results showed that the teaching materials developed were suitable for use in learning and could improve students^ mathematical reasoning abilities
