Developing Students' Responsibility Character in Mathematics Teaching and Learning through Problem-Based Learning

Abstract

One of the characters that affect students' success is responsibility. If responsibility is ignored, it will harm the students themselves or others. Therefore, we need a proper learning model to develop students' responsibility. Problem-Based Learning (PBL) is a model that is used to make students become more responsible. The purpose of this study was to develop the character of the students' responsibility through PBL model. This study was designed and implemented using a quasiexperimental design with equivalent time series. The subjects of this research were the junior high school students. The object of the research is the whole process and the results of the PBL model in mathematics to develop students' responsibility character. The data were collected through documentation, observations, and tests. The data were analyzed using repeated measures of ANOVA and regression test. The results showed that PBL model can improve students' learning outcomes and develop the students' responsibility character. It was marked by an increase in the percentage of the value of the character qualifications of the students' responsibility. In addition, there was an increase in the average value of the students' learning outcomes.
