THE EFFECT OF SCIENTIFIC APPROACH ON MATHEMATICAL CONCEPT UNDERSTANDING ABILITY AND MATHEMATICS LEARNING ACHIEVEMENT

Abstract

The purpose of this study is to describe whether the scientific approach in statistics material influences the ability to understand mathematical concepts. This research uses a quantitative method and a Pre-experimental design with a one group Pretest-Posttest model. Thus, pretest and posttest results were obtained within the research design so that experimental results could be compared with pre-experimental results. The research was conducted at SMA Al-Irsyad Kota Tegal. The subjects in this study were 32 students in the experimental class and 32 students in the control class. The data collection technique used pretest and posttest tests. Data analysis techniques were performed by testing the research instrument, analysis testing and hypothesis testing using paired t-test. Based on the research results obtained, it means that there is an influence on the model obtained t_hitung = -6.044, then |t_hitung| = 6.044. Then with the t_tabel distribution table = 2.039. Because |t_hitung| > t_tabel it can be concluded that H_o is rejected. Because the average value of understanding the concept of mathematics μ_1 ≠ μ_2, there is an influence of understanding the mathematical concepts of students before and after using a scientific approach.
