Abstract

Mathematical reasoning and resilience are essential skills that students need to master in the process of learning mathematics. Both of these skills can be cultivated through instructional models that stimulate students to construct their own knowledge by connecting learning to the real world. One instructional model characterized by these aspects is the Connected Mathematics Project (CMP). Consequently, the purpose of this study is to analyze the effectiveness of the CMP instructional model in enhancing mathematical reasoning and resilience abilities. This research employs a quantitative approach utilizing a quasi-experimental design, specifically the nonequivalent posttest-only control group design. The study was conducted in one vocational high school in Majalengka. Sample selection was carried out using the cluster random sampling technique, resulting in a total of 18 students in the experimental group and 18 students in the control group. The research instruments comprised a mathematical reasoning ability test consisting of three open-ended test items and a mathematical resilience questionnaire. The findings of this study indicate that: (1) students' mathematical reasoning abilities in the CMP instructional model are higher compared to those in conventional instruction; (2) the average percentage of students' resilience attitudes in the CMP instructional model is higher than those in conventional instruction; and (3) CMP instruction is effective in improving both mathematical reasoning and resilience abilities among vocational high school students.

Abstract

This study investigates elementary school students' 3D geometric thinking skills using the Van Hiele model. The research employed a grounded theory approach, utilizing tests, observations, and interviews to assess students' geometric thinking levels across two elementary schools in West Java and Central Java, Indonesia. A total of 6 test items were developed based on Van Hiele's theory, targeting the visualization, analysis, and informal deduction levels. Results showed varied performance between the two schools. Students from the Majalengka school demonstrated stronger visualization skills (77.14%), while those from the Surakarta school showed better performance in analysis (67.86%) and informal deduction (53.57%). Overall, students exhibited a good foundational understanding of 3D shapes, with most achieving the visualization and analysis levels. However, challenges emerged at the informal deduction level, where students often opted for simpler problem-solving methods over more systematic approaches. The study highlights the effectiveness of the Van Hiele model in assessing geometric thinking development and provides valuable insights for curriculum development and teaching strategies. It emphasizes the need to reinforce visualization and analysis skills while gradually introducing more abstract and systematic thinking in geometry education. The findings contribute to the understanding of elementary students' 3D geometric thinking skills and offer a basis for improving geometry instruction at the primary level.
