Abstract

Mathematical representation ability is an important skill for students to transform complex problems into simpler forms. However, field observations based on the pretest results of mathematical representation ability conducted at SMP Negeri 18 Bandarlampung show that many students have not yet mastered this skill. This is supported by the 2022 PISA results, which indicate that students’ mathematical representation ability is still categorized as low. Therefore, it is necessary to apply a learning model that can help students improve their mathematical representation skills. This study aims to determine the effect of the guided inquiry learning model on students’ mathematical representation ability. The population in this study consisted of all eighth-grade students at SMP Negeri 18 Bandarlampung in the odd semester of the 2024/2025 academic year, totaling 174 students distributed across six classes. Sampling was conducted using the cluster random sampling technique, selecting class VIII B (28 students) as the experimental class and class VIII D (29 students) as the control class. The research design used was the pretest-posttest control group design. The data in this study are quantitative data obtained from the students’ mathematical representation ability test. Based on data analysis using the Mann-Whitney U test, it was found that the improvement in mathematical representation ability of students who participated in guided inquiry learning was higher than that of students who followed conventional learning. Thus, the guided inquiry learning model has an effect on improving students' mathematical representation ability.

Abstract

The purpose of the study was to determine the implementation of learning with the STEM approach to improving students' mathematization skills. The STEM approach includes science, technology, engineering, and mathematics in real context. The study population was all VIII grade students of SMP Negeri 33 Bandarlampung in the odd semester of the 2024/2025 academic year which were distributed in six classes, namely VIII A to VIII F heterogeneously. Sampling was done using cluster random sampling technique, VIII E class consisting of 32 students was selected as the experimental class and VIII D class consisting of 32 students as the control class. The research design used was pretest-posttest control group design. The data of this research is quantitative data obtained from the students' mathematization skills test. The test consists of three descriptive questions that have been tested and meet the validity and reliability criteria. Based on data analysis using Mann-Whitney U test, it was concluded that the improvement of mathematization skills of students who participated in learning with STEM learning was higher than the improvement of mathematization skills of students who participated in conventional learning. Thus, the implementation of STEM learning can improve students' mathematization skills.
