Pengembangan Disposisi Dan Kemampuan Komunikasi Matematis Melalui Pendekatan Problem Solving Dalam Pembelajaran Di MA

Abstract

This study aims to explain the improvement of students’ mathematical disposition after being given by a problem solving approach to learning materials trigonometry in class X MA Ushuluddin Singkawang. The method used was a pre-experimental research with one group pretest-posttest research design. The sample in this study was students in class XB with 29 students. Based on t test using SPSS 23.0 for windows, it was obtained that the score for Sig. (2-tailed) = 0:01 <α = 0.05, which means that There is an improvement of students' mathematical disposition after the application of Problem Solving approach to learning materials trigonometry. Based on the Effect Size calculation, it was obtained that the contribution of the application of Problem Solving approach contributes to the ability of students' mathematical disposition as 49.83%.
