Abstract

Learning mathematics that can improve elementary school students' critical thinking skills is rarely done. Therefore, students' mathematical necessary thinking skills still need to improve. The realistic Mathematics Education (RME) learning model is expected to enhance mathematical critical thinking skills because of providing contextual problems to students. This study aims to determine the effect of the Realistic Mathematics Education (RME) learning model on students' critical thinking skills in mathematics. This research uses quasi-experimental research. The population in this study were students of class VI SDN 1 Kalikoa, Cirebon Regency. The sample selection in this study was carried out using a cluster random sampling technique to determine the experimental and control classes. In this case, two classes were selected: class VI A as the practical class and class VI B as the control class. The instrument for collecting data tests mathematical critical thinking skills on integer material. The results showed that the RME learning model is more effective than the direct learning model on students' critical thinking skills in mathematics. This is because the value of , and   at a significance level of 5% and DK of 40, which means , so H0 was rejected, and H1 was accepted. The results of this study can be used as input for teachers and prospective teachers to improve themselves concerning the teaching that has been done and the student's critical thinking skills that have been achieved by paying attention to the right learning model to improve students' critical thinking skills in mathematics.

Abstract

Purpose:This study investigates the impact of the Connected Mathematics Project (CMP) model on eighth-grade students’ ability to form mathematical connections at SMP Negeri 1 Martapura. It also examines how varying levels of self-efficacy relate to these connection skills and whether an interaction exists between instructional model (CMP vs. discovery learning) and self-efficacy in influencing outcomes. Method:A quasi-experimental, posttest-only control-group design was used. Two groups of eighth graders were assigned: one received CMP-based instruction and the other discovery-learning lessons. After the intervention, all students completed a standardized connection-skills posttest and a validated self-efficacy questionnaire. Participants were categorized into high- and low-efficacy subgroups. Two-way ANOVA assessed the main effects of instructional model and self-efficacy, as well as their interaction. Findings:Students taught via the CMP model scored significantly higher on mathematical connection tasks than those in the discovery-learning group. Independently, students with high self-efficacy outperformed those with lower self-efficacy. No significant interaction effect was detected, indicating CMP’s benefit across confidence levels. Significance:Findings demonstrate that CMP is a robust approach for enhancing mathematical connection skills regardless of student self-efficacy. They underscore the value of building learner confidence alongside innovative pedagogy and support broader adoption of CMP to strengthen real-world mathematical understanding.

Abstract

Many students in Indonesia continue to experience difficulties in mathematical problem-solving due to the persistent dominance of conventional teaching approaches that limit student engagement and creativity. This study examines the effectiveness of the Search, Solve, Create, and Share (SSCS) learning model integrated with GeoEnzo in improving students’ mathematical problem-solving abilities. A quasi-experimental design with a posttest-only control group was employed. Seventh-grade students from SMPN Terpadu Gunung Pelindung, East Lampung, Indonesia, were selected through cluster random sampling. Data were collected using a validated mathematical problem-solving test and analyzed using one-way ANOVA and Scheffe’s multiple comparison test to identify differences in performance among the four instructional approaches. The SSCS model integrated with GeoEnzo yielded the highest mean score (88.31), followed by the SSCS model without GeoEnzo (83.56), the conventional model with GeoEnzo (83.03), and the traditional model without technological support (77.08). ANOVA results indicated statistically significant differences (Sig. = 0.000) among the groups. The findings confirm that integrating SSCS with GeoEnzo effectively enhances students’ mathematical problem-solving skills. This research has implications for encouraging educators and curriculum developers to adopt a student-centered, technology-based learning approach to enhance higher-order thinking skills.
