Development of teaching modules in improving mathematical critical thinking skills based on problem-based learning

Abstract

The ability of grade VII students in mathematical critical thinking still needs to be improved so that a more effective learning approach is needed. The purpose of this study is to develop a teaching module to improve mathematical critical thinking skills based on Problem Based Learning (PBL). Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model is used as a research method in this study. The teaching module instrument was then validated by two experts. The results of the two validators showed that the developed teaching module was valid. Then the developed teaching module was tested on a small group of students to determine the readability and practicality of the teaching module. The results of the trial showed that the developed teaching module was practical. In other words, it shows that the developed Problem Based Learning (PBL)-based teaching module is able to improve students' mathematical critical thinking skills.
