PENERAPAN MODEL PROBLEM BASED LEARNING (PBL) UNTUK MENINGKATKAN KEMAMPUAN PEMAHAMAN KONSEP MATEMATIKA SISWA KELAS V SEKOLAH DASAR

Abstract

Abstract: This research is motivated by the low ability to understand students’ concept in mathematics in repeating concept both verbally and in writing, identifying characteristics or elements of a concept and applying alogarithmic concept.  This problem is caused because these problems are caused by learning that has not presented contextual problems (close to students), also students are less directly involved in the learning process so learning becomes less meaningful, students do not understand the material being studied and make student only memorize the formula. Therefore, the researchers tried to apply a Problem Based Learning model with the aim of increasing the ability to understand students’ mathematical concept in terms of the volume of an object that has space (cube volume and beam volume). This study used a qualitative approach with Classroom Action Research (CAR) method, Kemmis and Taggart model of two cycles. The stages of PTK consist of Planning, Implementation, Observation and Reflection. Data collection techniques carried out in the form of tests and observations. The research subjects were class V-D students of SDN B those in the sub-district of Sumur Bandung. The results of the study by applying a Problem Based Learning (PBL) model to mathematics learning matter the volume of an object that has space, experienced a good increase. This can be evidenced by the average value obtained in each cycle and increased learning completeness.
