Penggunaan Pembelajaran Dengan Pendekatan Brain Based Learning Terhadap Peningkatan Kemampuan Berpikir Kritis Matematis

The background problem in this research is the ability to think critically mathematically in Indonesia which is still classified as very low or below average. It is predicted that learning with the BBL approach can help students influence mathematical critical thinking skills. The objectives of this study are: 1) Analyzing differences in the improvement of students' mathematical critical thinking skills using learning with the BBL approach and conventional learning in terms of overall and gender differences; 2) Seeing students' activities towards the learning response of mathematics with the BBL approach. The research method that will be used in this study is a Mixed Method of the Embedded Design type and the Embedded Experimental Model type. sampling using a purposive sampling technique, the selected sample is class VIII-E as the experimental class and class VIII-B as the control class. The instrument used in this study was a test instrument that is a test of mathematical critical thinking skills and a non-test instrument namely an observation sheet. The subject that is presented as material is SPLDV. The results of this study are: (1) Mathematical critical thinking ability of students who use learning with the BBL approach is better than students who use conventional learning in terms of overall and gender differences, (2) 2) In learning with a Brain based learning approach students look active in learning mathematics
