Pengaruh penerapan model pembelajaran brain-based learning terhadap kemampuan pemecahan masalah matematik siswa

Abstract

This study aims to determine the ability of better problem solving of mathematics between classes that use the learning model of brain-based learning and the class using direct instruction learning model and to know the difference of mathematical problem solving ability from the category of early mathematical ability (high, medium, and low) As well as to find out the mean student self-efficacy higher between the two classes. This research is a quasi-experimental research with Post-test Only Control Group Design. The study population is all students of class VII MTs Negeri 2 Ciamis academic year 2016/2017. Selection of sample using purposive sampling technique which result is class VII D as a group that learn with a model of brain-based learning and class VIIE as a class which learn with direct instruction model. To get data result of research in the form of problem-solving ability score used an instrument in the form of description problem while to measure self-efficacy of student used questionnaire. Data analysis was performed using Mann-Whitney test, t-test and 2-way ANOVA test. The results showed: (1) the problem-solving ability of mathematics students using learning model of brain-based learning better than students using direct instruction model. (2) viewed from the ability of early mathematical (KAM) there is the difference of problem-solving ability of student mathematics learning using a model of brain-based learning by using direct instruction model. (3) there is no interaction between learning and KAM on students’ mathematical problem-solving abilities. (4) the average self-efficacy of students in the class who are learning with the higher brain-based learning model than those using the direct instruction model and both are positive.
