Abstract

This study aims to determine how the application of the problem-based learning model affects the learning outcomes of class X students regarding the material on systems of linear inequalities in three variables. This research is a pre-experimental one-group pretest-posttest design, with class X research subjects at Al-Hidayah Islamic High School. The instrument used is a validated system of linear inequalities in a three-variable material understanding test. The analyses used in this study are descriptive and inferential. The study found a big improvement in learning results after using the problem-based learning (PBL) method for the System of Linear Inequalities in Three Variables material, with an average score of 46.0833 before the test and 75.6667 after. The significant value of the hypothesis test is below 0.05, which means 0.00 < 0.05; thus, H0 is rejected and H1 is accepted. This study shows a significant difference in student learning outcomes when using the Problem-Based Learning (PBL) learning model.

Abstract

This study is important because of the many challenges faced by students in understanding word problems, especially those related to the concepts of LCM and GCF. Therefore, this study intends to examine students' mathematical disposition in solving word problems related to the concepts of Least Common Multiple (LCM) and Greatest Common Divisor (GCF). The research method used was a qualitative one, analyzing subjects in junior high school. This study was conducted in grade VII of junior high school MHI Bangsalsari. The instruments used include observation, problem study (questions), interviews, and documentation. We analyze the data using qualitative descriptions to solve word problems, utilizing Congklak as an educational tool. The research findings show that the congklak game serves as an excellent medium to increase students' interest in mathematics during the learning process. The implications of this research can help teachers in explaining topics by providing learning media that facilitate student understanding.
