Abstract

Mathematics belongs to its own thinkers, and every thinker has their own culture. So mathematics has an attachment to culture. Ethnomathematics emerged as a link between mathematics and culture. Ethnomathematics continues to evolve and embrace a wider range of studies with a cultural and social center. So the shift in focus towards the ethnomathematical paradigm is inevitable. This study identifies several philosophers' thoughts about the perspective of research results in the field of ethnomathematics. The debating paradigm in culturally based mathematical research. This study aims to describe ethnomathematics from various perspectives; the research method used is literature study. The results of this study can be summarized as follows: There are two paradigms related to the study of ethnomathematics, namely ethnomathematics as a cultural practice and ethnomathematics as a theory to analyze something different. There are various perspectives in ethnomathematical research, (1) there are several perspectives on ethnomathematics as a cultural practice, including ethnomathematics as a mathematicizing activity, the NUC system, mathematical analysis activities, mathematics projects, ethics, and ethnomathematics or mathematics. (2) as a theory, ethnomathematics can be looked at from different points of view, such as the QRS system, analogy mathematical activity, location interpretation, emic, and ethnomathematics and mathematics

Abstract

Philosophy of education is essentially the application of philosophical ways of thinking into the realm of education. Philosophy helps the process of implementing mathematics education. Philosophy directs and guides all processes that take place in mathematics education, so that education is carried out according to the right path and direction. The purpose of this study is to examine in depth how the philosophy of mathematics education perspective as a field of knowledge. The research method in this study used the literature study method. Data collection was carried out by collecting data from the library, from research journals and books and then reading, recording and processing these sources as research data. Philosophy of mathematics education as a field of knowledge provides a clear basis and direction for mathematics to become a means of thinking in discovering and developing various new knowledge and will then communicate the results of this knowledge so that it becomes useful and usable. Based on the study of ontology and epistemology, in carrying out mathematics education activities as a field of knowledge it is necessary to apply a philosophy of mathematics which involves the use of logic and the involvement of students in constructing their knowledge in solving existing phenomena or problems. Based on the axiological study, mathematics education as a field of knowledge will have value if students in the implementation of mathematics education are organized by involving the connections of mathematics with other sciences and connections with previously acquired knowledge.

Abstract

This study aimed to develop and evaluate a contextual problem-based essay test for assessing students' mathematical critical thinking skills on the topics of cubes and rectangular prisms. A quantitative descriptive design was employed involving 30 ninth-grade students from SMPN 31 Medan during the pilot-testing stage. Prior to implementation, the instrument was evaluated by expert validators to establish content validity. Empirical item validity was analyzed using the Pearson Product–Moment correlation coefficient, while internal consistency reliability was estimated using Cronbach's Alpha. The findings showed that all essay items met the criterion of empirical validity and that the instrument demonstrated moderate internal consistency, indicating its suitability for preliminary classroom assessment and pilot testing. The developed instrument assesses higher-order cognitive processes based on Facione's critical thinking framework, including interpretation, analysis, evaluation, inference, and explanation, through authentic contextual geometry problems. This study contributes to mathematics education by providing a contextually relevant assessment instrument with preliminary psychometric evidence that can support teachers in implementing authentic assessment of mathematical critical thinking skills. The findings also provide a foundation for future large-scale validation studies aimed at developing standardized assessment instruments for mathematics education.
