Keefektifan Pendekatan Open-ended dan Problem Solving pada Pembelajaran Bangun Ruang Sisi Datar di SMP

摘要

The aims of this research are to decide the effectiveness and the comparison of the effectiveness of open-ended and problem solving approach toward matter of flat side construct lesson viewed from achivement of reasoning ability, problem solving and mathematics communication. This study was a quasi experimental study using the pretest-posttest nonequivalent group design. The research population covered the entire VIII class students\u27 of SMP Negeri 1 Pandak, Bantul, Yogyakarta. From the population, classes of VIII F and VIII G were selected randomly as the research sample. To test the effectiveness of open-ended and problem solving approach, the one sample t-test was carried out. Then, to test the more effectiveness of the open-ended approach than the problem solving approach, the MANOVA was carried out and then continued by the t-Bonferroni test. The results of the study show that open-ended and problem solving approaches are effective and open-ended approach is more effective than problem solving approach in matter of flat side construct\u27 viewed from achivement of reasoning ability, problem solving, and mathematics communication in junior high school.
