Abstract

Mathematics communication skills are an essential aspect of math pedagogy, notably in the context of scientific learning. This study aims to describe students' performance in conveying math concepts in writing within the scientific learning context by focusing on three groups of students according to their level of mathematical communication skills: high, medium, and low. Based on the results, it is suggested to conduct further in-depth studies, including a more detailed analysis of the factors that influence students' mathematical communication skills in scientific learning. Furthermore, more effective learning strategies should also be developed to improve the students' mathematics communication skills, both oral and written. This further study could provide a deeper insight and be valuable for curriculum development and mathematics learning activities.

Abstract

The extrovert-introvert personality type has different energy sources for the individual, which affects the difference in thinking structures that will be obtained in solving problems. The thinking structure is the internal representation of students' mental activities that describes the flow of solving mathematical problems. Therefore, the mistakes made by students in solving mathematical problems require proper resolution, one of which is defragmentation. The purpose of this research is to analyze students' thinking structures related to personality types in solving problems through defragmentation. The approach used in this research is qualitative with a descriptive research type. Subject selection was carried out using purposive sampling technique with criteria being students who have extrovert-introvert personality types regarding mistakes in understanding and transformation. The research data consisted of answers, recordings of semi-structured interviews, and students' think-aloud results. The analysis techniques used are data reduction, data presentation, and conclusion drawing. The results show that defragmentation can help students with extrovert-introvert personality types to understand mistakes and perform transformations to reorganize their thinking structure. This is evidenced by the completeness of students' thinking structures from the stages of reading, understanding, transforming, analyzing, and evaluating.

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.
