Abstract

This study aims to understand how pre-service mathematics teachers conduct prospective analyses comprehensively. A qualitative research method with a case study design was used. The participant was Mrs N, a pre-service mathematics teacher who conducted research using DDR methodology in a grade 9 junior high school in Sindang, Majalengka, involving 48 students. Data were collected by analyzing empirical evidence from Mrs. N's prospective analysis process by uncovering the various stages of a prospective analysis. An iterative approach was used to analyze the data by refining the research questions through discussions and regular meetings with Mrs. N. The process ensured adaptability to new insights and understandings from the empirical data. Our findings reveal that the teacher draws upon fundamental philosophical principles from didactical design research, including hermeneutics, phenomenology, and ethnomethodology. By embracing these approaches, the teacher gains valuable insights into conducting research within an interpretive paradigm, allowing for a deeper exploration of the meaning of concepts, the purpose of learning, and the cultural influences that shape the educational process. Additionally, our study sheds light on the emergence of transpositional didactics theory as the prospective teacher delves into understanding the meaning of the geometrics transformation concept.

Abstract

This article discusses the ethnomathematics study of the Kampung Naga community in Tasikmalaya, Indonesia. Ethnomathematics can investigate the application of mathematical notions in these cultural activities. The study explored the forms of ethnomathematics in their ideas and activities in living their daily lives. This study uses an ethnomethodological approach with a realistic ethnographic design to show facts and provide broader meaning. Data were collected from five respondents through in-depth interviews. The study results show that the Kampung Naga community uses the modulo concept to determine the criteria for days that can be used to start various activities, such as building or repairing houses, working, farming, and other social activities. This exploration proves that mathematical concepts are integrated into cultural values ​​in everyday life.
