Abstract

This study aims to analyze the mathematical problem solving ability of class VIII students in solving problems regarding the Two Variable Linear Equation System (SPLDV). The basis of this research is the weak mathematical problem solving ability of junior high school students. The subjects of this study were 5 students of class VIII SMP from Bogor Regency. The approach used in this research is a qualitative approach with a descriptive method. This study uses a test tool to see the students' ability to solve mathematical problems in story problems using the Two Variable Linear Equation System (SPLDV) material. The data analysis technique used in this research is qualitative data analysis. Judging from the results of the analysis, some students still cannot solve the questions according to Polya's steps. From the results of research on 5 students, it can be seen that students' mathematical solving abilities when solving SPLDV story problems are still weak. Story questions about solving mathematical problems can help students think at a high level and be able to solve problems by following the steps given. Therefore, students still need exercises to understand the material and be able to solve problems related to solving these mathematical problems.

Abstract

The purpose of this study is to determine the effectiveness of Moodle-based e-learning which is used as a learning medium in terms of student understanding. This type of research is quantitative quasi-experimental research with a one group pretest posttest design. The population of this study was 2nd-semester students. The sample of this research was 36 students who were taken based on cluster random sampling technique. This research instrument uses math test questions that can be accessed through e-learning. The data analysis techniques were normality test as a prerequisite test, test for the difference in average pretest and posttest, test for the increase in the pretest and posttest results (N-Gain), and finally the effect size test. The results showed that the pretest data were not normally distributed, while the posttest data were normally distributed so that nonparametric statistical tests were carried out. The nonparametric statistical test used is the Wilcoxon test where the results show a sig score. (0.00) <0.05, which means that there is a difference between the average pretest and posttest scores. Furthermore, the n-gain test was carried out with a score of 0.53 which was in the medium category. This means that the pretest and posttest scores have a moderate level of improvement. And the last test results with the effect size test with a score of d = 1.47 which is in the strong effect category. This means that Moodle-based e-learning has a strong effect on students' understanding of mathematical concepts.
