Pembelajaran Berbasis Masalah untuk Meningkatkan Kemampuan Berpikir Matematis Tingkat Tinggi Siswa Sekolah Menengah Pertama
In this reform era, high level thinking ability is a necessary. This ability is however, not well-nurtured, since most lessons at school, especially math, does not provide students with the ability to develop their high thinking ability. This experiment study, therefore, is conducted to explore SMP students’ high level mathematical thinking and disposition through problem-based learning. The samples of this study are year 2 students in three SMPs in Bandung whereas the instruments in the study are test, mathematical disposition scale, and observation sheet. The findings, among others, suggest that open problem-based and structured problem-based learning are significantly better than conventional learning in improving students’ high level mathematical thinking ability based on school qualification difference and students’ intelligence. This different high level mathematical thinking ability is not gender based. In addition, the findings also suggest that the mathematical disposition ability of students who received open problem-based learning is better than that of those who received structured problem-based learning.
