Meningkatan Kemampuan Pemecahan Masalah Matematis Menggunakan Strategi Problem Based Learning Berbantuan Mind Mapping

Abstract

This study aims to determine the use of the Problem Based Learning strategy assisted by Mind Mapping to improve the mathematical problem solving skills of students of SMA Muhammadiyah Sukabumi in the 2019/2020 academic year on the subject of Statistics. This classroom action research was conducted in class XII IPS Muhammadiyah Sukabumi. In the first cycle there was no improvement, because students were still not used to solving problems with Mind Mapping assisted mathematical problem solving abilities, while in the second cycle students began to get used to solving problems with Mind Mapping assisted mathematical problem solving abilities properly. It can be seen from the results of the study that there is an increase seen from the average test result of 53.25 in the first cycle to 72.37 in the second cycle. This can be seen from the achievement of student learning activities in the first cycle an average of 54.5, in the second cycle an average of 65.19. From the results of the implementation of cycle I and cycle II, it can be concluded that the use of the Problem Based Learning strategy with the assistance of Mind Mapping can improve the mathematical problem solving skills of students at SMA Muhammadiyah Sukabumi.
