摘要：This study was conducted with the aim to notice the effect of Problem Based Learning in improving 8th grade Middle-School students' quantitative reasoning by employing measuring tools of an quantitative reasoning test and observation sheet, which were developed, was distributed to 50 experimental group students and 45 control group students, which makes 95 learners in total. This study was accompanied experimental by pre-test – post-test control group design. These participant are studying at 8.1th grade as the experimental group and 8.2th grade as the control group from a Middle-School 1 Pangkajene. Problem Based Learning was implemented on experimental group while Control group was implemented to current Curriculum. The result of conducted experimental group, it was be discovered that quantitative reasoning test and observation sheet of experimental group students are better than control group students. Furthermore, based on the results of the quantitative reasoning test, 86.1% of students obtained N-Gain more than or equal to 0.7. Therefore, it is possible to say that Problem Based Learning is more efficient than the learning in control group. So that quantitative reasoning test and observation sheet may be recommended for future studies.
