Abstract

Mathematics learning must be made more exciting and meaningful to overcome the perception that mathematics is a tricky subject. Students must be facilitated to build their knowledge through mathematics learning linked to realistic problems and integrated with Islamic values so that they can solve relevant daily problems. This research aims to develop a Social Arithmetic module based on Islamic values ​​and Realistic Mathematics Education (RME) to help junior high school students improve their problem-solving skills. This research uses R&D with the ADDIE development model. The development of the mathematics module consists of three stages, namely the preliminary, development, and evaluation stages. The resulting module prototype has been assessed as valid by material and media experts. Meanwhile, based on student and teacher responses to the questionnaire, the module was proven suitable for use in mathematics learning. In addition, the results of the paired t-test stated that the module was effective in improving students' problem-solving skills. Therefore, this research concluded that the Social Arithmetics module based on Islamic values ​​and RME that were developed has met the valid and practical criteria and has proven effective in improving the problem-solving abilities of seventh-grade junior high school students.

Abstract

The mathematical content in school mathematics must not be isolated from students known context students so the mathematics learning becomes meaningful. One context that is close to the student environment is a popular cultural context, for example batik crafts. This research aims to explore native batik of Kerinci related to transformation geometry content. The type of research used is ethnography. The instrument used in this research was the researcher himself (human instrument). The data collection techniques used are literature study and documentation. The data analysis techniques used are data reduction, data presentation and drawing conclusions. The results of the research show that the motif of native batik of Kerinci contains mathematical concepts in the geometry transformation content, namely reflection, translation, rotation and dilation. These findings can be integrated into mathematics learning through transformation geometry learning tools using the context of native batik of Kerinci.

Abstract

The impact of students' learning interest on their academic achievement is widely acknowledged; however, a significant number of students still exhibit low levels of interest. Employing effective learning media has been identified as a strategy to enhance learning interest, with dynamic tools such as Geogebra being recognized for their potential. This study aimed to describe students' learning interest by utilizing Geogebra in the context of the quadratic function topic. The research employed qualitative methods and a descriptive approach, involving four students as respondents from a private Senior High School in Yogyakarta, Indonesia. The instructional intervention consisted of mathematics lessons on quadratic functions using Geogebra. Data collection utilized unstructured interviews and close-ended questionnaires, incorporating 22 questions across five indicators of students' learning interest. The questionnaire results revealed an average percentage of students' learning interest falling within the strong category across all indicators. The findings suggest a strong preference among respondents for learning utilizing Geogebra, primarily attributed to its visually appealing interface. Consequently, students exhibited a high level of interest in studying the quadratic functions topic when facilitated by Geogebra.

Abstract

The students of the Nautical Fishing Vessel (Nautika Kapal Penangkap Ikan or NKPI) program at the State Secondary Fisheries Business School (Sekolah Usaha Perikanan Menengah Negeri or SUPMN) Pontianak cannot solve maritime problems properly, for example, shipping problems. One of the reasons is that maritime problems have not been integrated into the competency achievement indicators of Trigonometry topic. The aims of this research are to produce supplement of Trigonometry textbook that incuded marine problems. This research is a research and development (R&D) with 4D (define, design, develop, and disseminate) model. Data collection uses questionnaires, interviews, validation sheets, and maritime problem-solving test. The analytical techniques used include descriptive analysis and calculating the sign-test. The research results show that the supplement of Trigonometry textbook had a good impact on students’ skill in solving marine problems.

Abstract

Mathematical concepts can be found in the culture of the community, such as in daily activities and handicrafts. One type of handicraft is the pencar, a cast net (throw net) fishermen use to catch fish. This research aims to explore the arithmetic sequences involved in making a pencar. This research uses qualitative research with ethnography. The research was conducted in Marong Village, West Nusa Tenggara, Indonesia. Data were obtained by direct observation of the pencar and the process of making it, interviews with cast-net handycrafters, and literature studies on arithmetic sequences. The results of this study show that there are three arithmetic sequences in the pencar. The first sequence, the number of anak (meshes) between each anakan (widener) in the n-th widener row, is 3, 4, 5, and so on, formulated by Un = 3 + (n - 1). The second sequence, the number of anakan (widener) in the n-th widener row is 44, 45, 46, and so on, formulated by Un = 44 + (n - 1). The third sequence, the number of lubang (meshes) in the n-th anakan is 44, 90, 138, 188, and so on, formulated by Un = n^2 + 43n. The arithmetic sequences in pencar can be used as a problem context for culture-based learning in the arithmetic sequence topic.
