Abstract

Mathematics can be found in cultural aspects. Moreover, Indonesia has a variety of cultures that can be explored and used as mathematics learning resources. Existing mathematics learning has yet to integrate cultural elements that are close to students. The aim of this study is to examine the findings of geometric objects and mathematics activities in the Moekhlas Sidik Red Mosque. The research method used was an ethnographic study and data collection techniques in the form of observations, documentation, and interviews. The obtained data were analyzed using an interactive model: data reduction, data presentation, data interpretation, and conclusion. This study found that the geometric objects include 2D shapes, 3D shapes, and geometric transformations. The 2D shapes observed are triangles, trapeziums, squares, rectangles, rhombuses, and semicircles. The 3D shapes that can be observed are rectangular prisms. Geometric transformation is the use of the principles of translation, reflection, and rotation. The mathematical activities that can be explored include creating tile patterns, finding the purpose of tile patterns, and drawing 2D shapes using geometric transformation principles. In addition, the existence of the Moekhlas Sidik Mosque provides socioeconomic value that has an impact on the surrounding community.

Abstract

The integration of technology in mathematics education is a tangible manifestation of the rapid development of the times. Therefore, teachers must use technological devices to ensure students stay competitive in the global arena. This study aims to describe the distribution of TPACK skills among pre-service mathematics teachers and monitor their development during their microteaching experiences. This research is a qualitative descriptive study. The participants in the study were eleven students at UIN Sjech M Djamil Djambek Bukittinggi who were taking a microteaching course in the even semester of 2023/2024. The instruments used were the TPACK questionnaire and observation sheets. Based on the observation, in the first session, some subjects were unable to use or operate the software they had downloaded, and many quiz applications encountered problems because they could not be opened. The challenges faced included paid software and issues operating the software on different laptops. It is suspected that one student did not attend because she was not prepared to present. Additionally, the development of skills for each TPACK aspect generally showed improvement in subsequent sessions. The subjects generally used presentation slide applications such as Microsoft PowerPointTM and CanvaTM to explain the material and conducted evaluations by giving quizzes through applications such as QuizizzTM, KahootTM, WordwallTM, and BamboozleTM. The results show that the students' skills based on the TPACK Questionnare were at a moderate level with an average score of 3.38. However, there are differences between the results of the questionnaire and the observations carried out. For instance, in the aspect of Technological Pedagogical Knowledge especially for item "I can utilize available technologies as a learning aid". The questionnaire showed a high rating 3.63. On the other hand, observations indicate that students' abilities are still lacking, indicating that students have much to learn, especially in the use of technology in the learning process to enhance the learning environment in mathematics.

Abstract

In the body of knowledge in mathematics education research, fractions are one of the researchers' concerns. The reason is because fractions are very difficult for students to understand. This study explores elementary school students' knowledge and obstacles in dealing with the multiplication of fractions. This study employs descriptive quantitative and qualitative approaches. Data were collected using the fractional knowledge test administered to 56 fifth-grade students and cognitive semi-structured interviews with six students depending on their test scores. The results of this study show that students’ knowledge of fractions is restricted, with challenges interpreting context-based problems and the usage of “of” terms. Another finding shows that students’ procedural knowledge is more dominant than conceptual knowledge. To develop students’ knowledge of fractions, the portion of context-based learning must be an emphasis. The importance of developing research-based textbooks based on a suitable learning trajectory is highlighted.

Abstract

Spatial reasoning is essential for success in mathematics and STEM fields, yet it is often overlooked in primary school curricula. This study investigates the levels and progression of spatial reasoning abilities among primary school students in Indonesia, focusing on mental rotation, spatial orientation, and spatial visualization. A cross-sectional study involving 135 students from Year 2, Year 4, and Year 6 used an adapted Spatial Reasoning Instrument. Results showed below-average spatial reasoning abilities overall, with notable improvement with age: Year 2 students averaged a Spatial Reasoning Test Score (SRTS) of 1.66, Year 4 students 2.02, and Year 6 students 2.68. Challenges were identified in tasks requiring multi-step spatial reasoning, spatial language comprehension, and 2D-3D transformations, particularly among younger students. These findings highlight the need for curriculum enhancements and targeted interventions to develop spatial reasoning skills from an early age, improving academic performance in STEM subjects.

Abstract

A systematic literature review explores research areas related to pre-service teachers' beliefs about Mathematics to consider them in the development of teacher professional education. The articles from Scopus, DOAJ, and ERIC using the PRISMA diagram were extracted, and they included four stages: identification, screening, eligibility, and quality assessment. In total, 26 articles were analyzed. From the analysis, it was found that the country that has conducted the most research on beliefs is Turkey; the method most often used in various studies is quantitative; the characteristics of the sample are mostly prospective mathematics teachers; women dominate the gender of the sample; the construct that appears most often in research is beliefs about teaching mathematics; the instrument most often used is a questionnaire; there are research results from various literatures presented to add insight to readers; and another domain that often appears in research related to pre-service teachers' beliefs about mathematics is self-efficacy. The various research results reveal that women dominate gender issues. It is interesting to explore this topic more deeply, given that men have the same role as women in improving and fostering professionalism.

Abstract

Mathematical concepts will be embedded if they can be imagined and appear in everyday life. Therefore, this study aims to develop Local Instructional Theory in context-based matrix learning. Design research is adopted to achieve these objectives. The design research has three stages, namely, preliminary experiment, teaching experiment, and retrospective analysis. The study was conducted at a high school on the outskirts of the capital, involving 39 students of class XI. The data was collected employing tests, observation, interviews, worksheets, and documentation in the form of video recordings, photos, and student journals. The results indicated that students were able to construct their concept of matrices through the context of a favorite or a hobby as a starting point in compiling and defining a matrix, and continued with the matrix multiplication concept (matrix scalar multiplication as repeated addition; terms and products of two matrices).
