Pengaruh Model Brain Based Learning untuk Meningkatkan Kemampuan Koneksi Matematis dan Pencapaian Self Concept Siswa

Abstract

The purpose of this study was to analyze the improvement of students' mathematical connection skills and self-concept with a brain based learning (BBL) model with a scientific approach. The background of this research is that the reality on the ground shows that students' mathematical connection abilities are not as expected. One of the factors causing these problems is learning that does not provide flexibility for students to optimally empower the potential of the brain. This resulted in students having difficulty connecting between materials and the level of student confidence that was lacking. This study uses a quantitative approach with a quasi-experimental method. The sample in this study were 37 students in the control class and 36 in the experimental class. The instrument used is a mathematical connection ability test and a self-concept questionnaire. The results of the study are: 1) the increase in mathematical connection ability with the BBL model is higher than with the scientific approach; 2) the achievement of students' self-concept with the BBL model is better than the scientific approach; 3) there is a relationship between the ability of mathematical connections and students' self-concept with the BBL model. Based on the results of the study, it is hoped that the next researcher can choose a method that can encourage the growth and development of students' positive self-concepts, in order to influence students' beliefs about their abilities, and ultimately affect student achievement.
