PENERAPAN BAHAN AJAR TRIGONOMETRI DENGAN MODEL MATEMATIKA KNISLEY UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS MATEMATIK MAHASISWA

Abstract

The aim of this study is to determine the improvement of students' critical thinking skills in trigonometry courses whose learning uses trigonometric teaching materials with knisley mathematical models compared to those that do not use teaching materials. The method used in this study is quasi-experimental used pretest posttest nonequivalent control group design with a sample 53 students in experiment class and 51 students in control class. The instrument used in this study is a test of critical thinking skills as much as 5. Instrument data is used to obtain n-gain data which is than analyzed using statistical tests with the stages of normality test, homogeneity test and t’ test. Based on the results of the data statistic, it can be concluded that the improvement of students' critical thinking skills in learning using trigonometric teaching materials with knisley mathematical models is better than those who do not use teaching materials.
