Abstract

This research aims to produce a contextual approach-based mathematics module on cubes and rectangular prisms for 8th-grade junior high school students. The type of research used is Research and Development (R&D) with a modified 4-D research model into 3-D, namely Analysis, Design, and Development. The instruments used in this research are validation and practicality questionnaires. The results of the development of mathematics learning modules have been validated by three validators, with the overall average assessment aspects such as didactic aspects, content, language, and appearance reaching 3.60 with a criterion of very valid. Furthermore, the practicality of the modules is assessed based on trial and evaluation using teacher response questionnaires, with the average practicality score of the contextual-based mathematics module reaching 94% and the student response questionnaire reaching 84.25%, both categorized as very practical. Therefore, this mathematics learning module has been proven to be very valid and highly practical.

Abstract

This study aimed to evaluate the level of proportional reasoning among middle school students in their ability to solve mathematical problems involving proportions. Proportional reasoning is essential for understanding and mastering various mathematical concepts, serving as a fundamental skill for higher-level mathematics. A qualitative case study design was employed, involving 28 eighth-grade students from a school in Bandung, Indonesia. The participants were assessed using a set of proportion-related problems, including numerical comparison, non-proportional (additive), direct proportion, and inverse proportion tasks. The analysis focused on categorizing the students' problem-solving strategies into distinct levels of proportional reasoning, ranging from non-proportional to formal proportional reasoning. Additionally, three students representing high, moderate, and low mathematical performance were selected for in-depth interviews to explore their reasoning processes when addressing proportion problems. Data analysis included administering tests, reviewing students' problem-solving strategies, conducting in-depth interviews, and evaluating their proportional reasoning abilities. The findings revealed that students with high and moderate mathematical performance exhibited proportional reasoning levels ranging from 0 to 3, whereas low-performing students displayed levels ranging from 0 to 2. Moreover, students generally faced difficulties distinguishing between proportional and non-proportional problems. Even when correct answers were provided, many lacked a deep understanding of direct and inverse proportion concepts. The study also discusses several implications for enhancing students' proportional reasoning skills.

Abstract

The integration of three-dimensional geometry in secondary mathematics education plays a crucial role in developing students' spatial reasoning and problem-solving skills. However, textbooks often present limitations in structuring tasks, techniques, and justifications, which may lead to learning obstacles. Despite the importance of well-designed instructional materials, there is a lack of comprehensive studies analyzing Indonesian mathematics textbooks using both the praxeological framework and the learning obstacles perspective in didactic situations. Addressing this gap, this study examines a Grade XII mathematics textbook in Indonesia, focusing on three-dimensional geometry through a structured content analysis. The analysis categorizes tasks based on praxeological components, including types of tasks, solution techniques, technological justifications, and supporting theories, while also identifying potential learning obstacles related to the clarity of visual representations and contextual problem diversity. The findings reveal that the textbook includes 10 types of tasks, solved using 6 techniques, supported by 7 forms of technological reasoning, all grounded in three-dimensional geometry concepts. The presentation of tasks is systematically structured and balances conceptual and procedural aspects, minimizing significant didactic obstacles. However, epistemological obstacles were identified, primarily due to limited visualizations and a lack of diverse contextual tasks, which may hinder students’ flexibility in applying three-dimensional geometry concepts. These findings highlight the need for improved task design and enhanced visual representations to foster deeper conceptual understanding and adaptability in problem-solving. This study contributes to mathematics education research by providing empirical insights into textbook design and its impact on students' learning processes, offering recommendations for more effective instructional material development.

Abstract

Spatial thinking is a crucial ability to be mastered by students. On the other hand, the rapid development of technology in education, such as augmented reality (AR), is predicted to increase significantly in 2035. This technology should be utilized to provide new insights for students. However, the condition of learning resources related to AR currently needs to be improved. This study aims to design mathematics teaching materials on geometry materials using AR to improve spatial thinking skills. This study uses the Plomp model development research, which consists of three stages: preliminary, prototyping, and assessment. It is important to note that this paper reports results from preliminary. This article reports by collecting data through literature studies and questionnaires to mathematics teachers in the Rokan Hulu district. The findings reveal that the use of GeoGebra as an AR builder in Indonesia still needs to be created because of the excellent potential of Geogebra. AR learning resources on geometry at the high school level also need to be improved. Teachers agree that learning using technology has become necessary and are interested in using AR, especially in the geometry field. Based on the findings, we designed and developed Geogebra AR-assisted teaching materials based on these findings to improve spatial thinking skills.

Abstract

LKPD as a learning resource plays an important role for students in learning activities to be actively involved in understanding concepts. The problem is that teachers have not been motivated to make their own LKPD according to the characteristics and abilities of students. This is because teachers do not understand the importance of using LKPD which are prepared by themselves in learning and the mechanics and technicalities of compiling LKPD correctly and well. The teacher only uses textbooks and LKPD which contains a summary of the material, sample questions and practice questions without any process of finding concepts. Students receive information from LKPD without being able to explore their ability to obtain information/concept discovery independently. In connection with these problems, training and assistance in the preparation of LKPD was carried out at SMPN 3 Rambah Hilir. The teacher participated in this activity enthusiastically. This can be seen from the positive response given by dmana there were 15.4% gave a very good response and 76.9% gave a good response. The material and assistance provided in the training helped teachers make a better LKPD, namely 15.4% stated that it was very good, 69.2% stated that it was good and 15.4% stated that it was quite good. Teachers became motivated to make their own LKPD, namely there were 15.4% very good, 76.9% good and 7.7% enough.
