Abstract

This research was motivated by the low ability to understand mathematical concepts of elementary school students, especially in non-standard measurement material. This problem is caused by learning that is still conventional and the lack of use of conceptual and interesting learning media. This research aims to analyze the effect of implementing Realistic Mathematics Education (RME) assisted by animated videos on elementary school students' ability to understand concepts. This research uses a quantitative approach with a quasi-experimental method and a Nonequivalent Pretest-Posttest Control Group design. The subjects of this research consisted of 40 class I students at SDN 188 Pekanbaru who were divided into experimental classes and control classes. Data collection techniques use tests, observation and documentation. Data analysis was carried out through normality test, homogeneity test, independent sample t-test, and N-Gain test. The research results show that there is a significant influence with a significance value of 0.049 <0.05. The post-test average for the experimental class was 70, while the control class was 57.5. The N-Gain test results showed an increase in the experimental class of 0.42 in the medium category and the control class of 0.17 in the low category. Thus, the implementation of RME assisted by animated videos on non-standard measurement material is quite effective in improving the conceptual understanding ability of class I students at SDN 188 Pekanbaru.

Abstract

This study was motivated by the low level of mathematical conceptual understanding among second-grade elementary school students, which is attributed to a lack of variety in the instructional models used by teachers as a result, teachers tend to rely on conventional teaching methods that do not sufficiently engage students. This study aims to determine the effect of the Contextual Teaching and Learning (CTL) model on students’ mathematical concept comprehension regarding two-dimensional shapes in second-grade elementary school. The research method used in this study is quantitative research with a quasi-experimental design. This study utilized two groups: an experimental group and a control group, with a total sample of 58 students from classes IIA and IIB at SD Negeri 189 Pekanbaru. The research instruments consisted of multiple-choice questions for the pretest and posttest, which had been validated beforehand. The data obtained were analyzed using an independent samples t-test, with results showing that students’ mathematical concept comprehension ability yielded a significance value of 0.000 (< 0.05), thus, the hypothesis testing results indicate that Ha is accepted and H0 is rejected. Based on this study, it can be concluded that there is a significant difference in students mathematical concept comprehension between those using the Contextual Teaching and Learning (CTL) model and those using conventional methods. Thus, the Contextual Teaching and Learning (CTL) model is effective as a learning model because it connects material on plane figures to students’ real-life contexts, thereby improving students’ mathematical concept comprehension.

Abstract

This study aimed to determine the effect of the Problem Based Learning (PBL) model on the mathematical representation ability of fifth-grade students at SD Negeri 136 Pekanbaru in solving mixed fraction word problems. This study used a quantitative approach with a Quasi-Experimental research type and a Nonequivalent Control Group Design. The research sample consisted of an experimental class and a control class. The data collection technique used a mathematical representation ability test. Data analysis was carried out through normality tests, homogeneity tests, hypothesis tests, and the N-Gain Score test. The results showed that there was an effect of the Problem Based Learning (PBL) model on students’ mathematical representation ability. The hypothesis test results showed a significance value of less than 0.05. In addition, the N-Gain Score test result of 48% indicated that the Problem Based Learning (PBL) model was quite effective in improving students’ mathematical representation ability. Therefore, the Problem Based Learning (PBL) model had an effect on the mathematical representation ability of fifth-grade students at SD Negeri 136 Pekanbaru.
