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

Multicultural learning is a strategy for creating a learning environment and designing a learning experience that integrates culture as part of the learning process. In multicultural learning, culture becomes a method for students to transform the results of their observations into creative forms and principles of nature so that the role of students is not merely to imitate or receive information, but to act as a creation of meaning and understanding. Subjects such as Citizenship Education, Social Sciences, Natural Science, Cultural Arts and Skills are considered to contribute to multicultural learning, but mathematics subjects can also contribute. The research aimed to find out how the use of multicultural learning in mathematical learning, on flat building materials, affected students' racism and social attitudes. This is a qualitative descriptive study that uses the interview method to gather data. The results will be qualitatively analyzed. Interviews were conducted to find out how multiculturalism is integrated into learning, how knowledge construction is built through cultural influences, how prejudice reduction occurs, how equality pedagogy is implemented, how the empowerment of school culture occurs in the learning process, and how it impacts in tackling racism and social attitudes of students after using such learning.

Abstract

There are many tribes in Indonesia and each tribe has its own uniqueness. However, this uniqueness certainly has a value that is considered important for each follower. The unique values of each tribe influence various aspects in the lives of the individuals in that tribe. The Toba Batak ethnic group has a cultural philosophy to guide their lives. To achieve this philosophy they carry out education because they are aware that education is a step in achieving this philosophy. The Toba Batak tribe has many life philosophies or life guidelines. One such philosophy is Anakkon Hi Do Hamoraon in Ahu. The research method used in this research is descriptive qualitative. This research aims to: examine the cultural philosophy of the Toba Bataks in North Tapanuli in shaping the mindset of the Toba Batak ethnic group regarding the importance of education. This research has 2 objectives, namely: 1). Knowing the condition of education in North Tapanuli, and 2). Knowing the role of Toba Batak cultural values in community education in North Tapanuli. The research was carried out by conducting field observations, literature studies and in-depth interviews with three types of sources, namely: government, community leaders and the community. The research results were analyzed using qualitative descriptive methods. The research results show the role of local cultural values in increasing public awareness of obtaining education. Through education, society achieves 3 main ideals, namely hamoraon, hagabeon and hasangapon so that society is taken into account in daily life and in cultural activities. The cultural value of anakkon ki do hamoraon in ahu has a unique educational significance.

Abstract

The initial abilities of students in the Integral Calculus course reveal that many have not yet grasped the fundamental concepts of integration. Out of 20 students given integral problems, only 6 students (30%) were able to answer correctly, while 14 students (70%) made errors. These errors in the Calculus course need to be analyzed further to assist lecturers and students in identifying weaknesses in the learning process and address or at least reduce similar mistakes in the future. This study employs a descriptive qualitative approach, with 20 second-semester students from the Mathematics Education program at IAIN Lhokseumawe as the research subjects. The findings indicate that students with very high and high computational thinking skills did not make errors compared to those with moderate, low, and low computational thinking skills. Students with moderate computational thinking skills tended to make errors in processing and answer writing. In contrast, students with low and very low computational thinking skills more frequently encountered transformation, processing, and answer-writing errors. Transformation errors occur when students make mistakes in calculations or during the process skill stage. These errors are often caused by students’ difficulty structuring solution steps, leading to misunderstanding the problems. Most students were also unable to reformulate the problems into forms suitable for the appropriate solution method, resulting in their inability to proceed with the calculations. Based on the error analysis using Newman’s Error Analysis (NEA) method, the most common types identified were transformation, processing, and answer-writing errors.
