Abstract

Mathematical understanding is a fundamental component of mathematics learning, as it underpins the development of other essential mathematical competencies. However, many students tend to rely on memorizing formulas without achieving a deep conceptual understanding. This study aimed to analyze students’ mathematical understanding in the topic of three-dimensional shapes with flat surfaces at the junior high school level. A descriptive qualitative approach was employed, involving 25 students from SMP Negeri 12 Pekanbaru as research participants. Data were collected through two open-ended test items and semi-structured interviews, and analyzed using indicators of mathematical understanding, including restating concepts, applying procedures algorithmically, and connecting concepts within and beyond mathematics. The results showed that the majority of students (76%) demonstrated a low level of mathematical understanding, while 12% were classified as having moderate understanding and 12% as having high understanding. Students in the high category were able to fulfill all indicators, whereas those in the moderate and low categories experienced difficulties, particularly in applying procedures algorithmically and establishing conceptual connections. These findings indicate the need for instructional practices that emphasize conceptual understanding and support students in meaningfully connecting mathematical concepts to problem-solving contexts.

Abstract

Mathematical reflective thinking is an essential higher-order thinking skill that supports students in analyzing, evaluating, and drawing conclusions during problem solving. This study aims to examine the effect of the Discovery Learning (DL) model on students’ mathematical reflective thinking skills. The research employed a quantitative approach using a quasi-experimental design with a pretest–posttest control group. The population consisted of all Grade VIII students of SMP Negeri 9 Bandar Lampung in the 2024/2025 academic year, with two classes selected as the experimental and control groups through cluster random sampling. Data were collected using a mathematical reflective thinking skills test and analyzed using N-Gain analysis and an independent sample t-test. The results show that students taught using the DL model achieved higher posttest scores and greater improvement in mathematical reflective thinking skills compared to students taught through conventional learning. The average N-Gain of the experimental class was higher than that of the control class, and hypothesis testing indicated a significant difference between the two groups. These findings indicate that the Discovery Learning model has a positive and significant effect on students’ mathematical reflective thinking skills and can be effectively implemented in mathematics learning.

Abstract

Technological developments demand adaptation in the world of education, particularly in the integration of technology into mathematics learning. Prospective student teachers need to possess the competencies to create innovative learning media that are not only content-accurate but also visually and technologically engaging. This study aims to describe the implementation of the Project-Based Learning (PjBL) model with STEAM (Science, Technology, Engineering, Art, and Mathematics) content in producing Android-based mathematics learning media. The method used was descriptive qualitative through triangulation of observation data, discussions, and analysis of the output product. The results showed that PjBL facilitated students in practicing the engineering cycle of media creation. However, obstacles were encountered in the Technology and Mathematics elements, where students experienced difficulty transforming textbook content into the system logic of an Android application. Furthermore, technical barriers to mastery of tools (Technology) such as iSpring Suite were a major challenge. Nevertheless, this approach successfully encouraged students to integrate art elements into interface design and mathematical logic within a single, integrated product. It was concluded that the implementation of PjBL with a STEAM nuance effectively helped lecturers and students produce usable digital media products.
