Implementation of Brain-Based Learning Model to Increase Students' Mathematical Connection Ability on Trigonometry at Senior High School

Abstract

This study aims to determine differences in mathematical connection ability of students before and after the implementation of the Brain-Based Learning (BBL) model, to know the differences in the improvement of students' mathematical connection abilities between the application of BBL models and direct learning, knowing the feasibility of BBL models and student activities on trigonometry in class X Senior High School (SMA) in Singkawang. The method in this study is the experiment with the Quasi-Experimental design and non-equivalent pretest-posttest control group design. The sample in this study was determined by purposive sampling technique. The instruments used are mathematical connection ability tests, Learning Implementation Plan (RPP), implementation observation sheets, and student activity observation sheets. The results showed (1) there were significant differences in students' mathematical connection abilities when BBL models were applied, (2) there were differences in mathematical connection ability improvement between students who received BBL model with students who received direct model learning, (3) BBL model implemented very well in class X Senior High School, and (4) student learning activities are classified as active when applied BBL model in Senior High School.
