Development of KADIR Learning Model to Enhance Students' Mathematical Problem Solving Skill

摘要

The purpose of the present study was to develop KADIR (Koneksi, Aplikasi, Diskursus, Improvisasi and Refleksi) learning model kits for improving students' Mathematical Problem SolvingSkill (MPSS). This study was a research and development study employing the 3-D (Define-Design-Develop). The field try-outs were conducted in Junior High School in Depok, which instruments consisted of the experts' validation sheet, the observation sheet for students learning activities, test, and questionnaire and interview sheet on students' responses toward learning activities. The collected data were analysed using qualitative and quantitative techniques. The study produces KADIR learning model kits consisting of student's worksheet, lesson plans, and an instrument of MPSS. The kits were revised based on the inputs from the experts and the results of the field try-outs. In validity aspects, all of developed teaching kits are valid. In practical aspects, in the first and the second try-outs, both the teachers and the students can use the teaching kids well. This study shows that KADIR learning model can enhance students' MPSS. The improved indicators of MPSS in the field study include identification of problems, description of the physics, planning the solution, executing the plan, and evaluating the answer. The implementation of KADIR learning model also improves students' activity and the students' positive response toward learning activities.
