Improving Students’ Mathematical Representation Ability Through Challenge-Based Learning with Android Applications

Abstract

The rapid advancement of the latest technology, the absence of interactive multimedia in schools, and the inferior ability of students’ mathematical representation creating an alternative breakthrough in developing Android-based learning applications. The purpose of the research was to improve the ability of students’ mathematical representation through Android Challenge-based Learning. The quasi-experimental, held at Bandung. It involved 79 students, 39 experimental classes and 40 control classes. The findings indicated that there an increased ability of mathematical representations of students with Android-based Challenge-based Learning than students in the control group. There was no difference in the performance of mathematical representation between students with Challenge-based Learning based on Android and conventional learning based on mathematical prior knowledge in the high, medium and low categories. There was interaction in the types of challenge-based learning between the student with Android applications and expository learning based on prior knowledge of mathematics in the high, medium, and low on the ability of students mathematical representation. Challenge-based learning based on Android facilitated the process of conflict, discovery, social interaction, and reflective processes of students so that the ability of mathematical representation is improved while the material easily understood and exciting.
