Empirisme dan Falibilisme dalam Filsafat Matematika: Sebuah Kajian Epistemologis dan Implikasinya dalam Pendidikan Matematika

Alfiatun Tadqiroh, Anggun Badu Kusuma — Wed, 02 Jul 2025 00:00:00 +0000

The philosophy of mathematics plays a crucial role in explaining the origins and status of mathematical knowledge. In the context of mathematics education, epistemological understanding is increasingly relevant, given the persistent dominance of absolutist views that regard mathematics as a certain and final body of knowledge. However, approaches such as empiricism and fallibilism offer alternative perspectives that are more reflective and dynamic. This study aims to explore the philosophical ideas of empiricism and fallibilism in mathematics and analyze their implications for mathematics education. The research employs a systematic literature review with a thematic analysis approach to identify key themes from each perspective and their potential contributions to educational practice. The findings reveal that empiricism emphasizes the role of concrete experience in the formation of mathematical knowledge, while fallibilism highlights the open and non-absolute nature of mathematical truth. The integration of these two approaches has the potential to support a contextual learning environment that embraces error and fosters critical thinking. Therefore, this study contributes theoretically to the development of mathematics education that is more humanistic, reflective, and centered on students' understanding.

Fadilla Dwi Pangestuti, Sudi Prayitno, Junaidi Junaidi, Muh Turmuzi — Sat, 05 Jul 2025 08:38:46 +0000

This research was conducted to describe the mathematical representation abilities of eighth-grade students at SMPN 13 Mataram on the topic of Two-Variabel Linear Equation Systems (SPLDV), viewed from the introvert and extrovert personality types. A qualitative research method was used with descriptive approach. The subjects were chosen using purposive sampling and involved 4 students selected based on personality questionnaires and mathematical representation ability tests, followed by interview. Data was collected through non-tes instruments Eysenck Personality Inventory (EPI), essay questions on mathematical representation ability test and interviews which is then analyzed descriptively to find out the differences in verbal, symbolic and visual representation abilities between introvert and extrovert students. The data analysis uses the interactive analysis model from Miles & Huberman. The results showed that introvert students have very good verbal and symbolic representation skills, but still weak in visual representation because none of them could answer correctly. Extrovert students also have good verbal and symbolic representation skills, more confident in answering, but less detailed and tend to rush. Just like introvert, extrovert students also couldn’t represent SPLDV visually in the right way. The main difficulty for both personality types is in converting the information in the problem into a visual representation caused by a lack of experience and practice in drawing graphs.

Kiki Insani Sholihah, Isnaini Qoiriyah, Ari Wibowo — Thu, 10 Jul 2025 07:18:16 +0000

This study aims to implement and compare the effectiveness of the secant method in solving nonlinear equations using two different computational applications microsoft excel and maple. The research adopts a descriptive qualitative approach with a comparative methodology. The secant method, which is part of numerical methods commonly used to determine the roots of nonlinear equations, was separately implemented on each software platform. The process of solving the nonlinear equation through secant iterations was explored and executed independently on both tools. The results of the implementation show that both applications are capable of producing similar root values for the given equation. However, Microsoft Excel offers an advantage in visualizing the iterative process in a detailed and step-by-step manner, allowing users to clearly understand how the solution is derived through each stage of calculation. In contrast, Maple tends to present the final outcome of the iteration process without displaying the detailed steps involved. This study analyzes the strengths and limitations of each application in the context of implementing the secant method for solving nonlinear equations.

This study was motivated by the findings of learning obstacles experienced by students in the multiplication of count numbers. The findings were obtained through the learning obstacle test at the preliminary study stage and supported by data showing the low numeracy skills of students in Indonesia. The identified difficulties include: (1) understanding the meaning of story problems, (2) understanding the concept of multiplication as repeated addition, (3) performing mathematical calculation processes, and (4) applying the concept of multiplication in everyday life. To overcome these problems, a didactical design was developed as an effort to minimize learning obstacles while facilitating students' numeracy skills. This research uses the Didactical Design Research (DDR) method which includes three stages, namely prospective analysis, metapedidactic, and retrospective. Data were collected through observation interviews, tests, questionnaires, and documentation studies, then analyzed through data reduction, presentation and verification. The results showed that the application of didactical design had a positive impact on multiplication learning. This is evidenced by 89% of students who gave positive responses, as well as the reduction of learning barriers that had previously been identified, especially the reduction of difficulties in understanding the concept of multiplication. However, there are still some aspects that need to be improved to optimize learning and anticipate other potential obstacles.

Self-efficacy is an important factor that influences students' success in solving mathematical problems. This study aims to describe the differences in self-efficacy characteristics between students with high and low self-efficacy scores in solving mathematical problems on the topic of the Pythagorean Theorem. This research employed a qualitative approach involving two junior high school students selected based on the results of a self-efficacy questionnaire. Data were collected through questionnaires, mathematical problem-solving tests, unstructured interviews, observations, and time triangulation to obtain accurate and in-depth data. The research instruments included a self-efficacy questionnaire based on Bandura's theory with seven indicators, as well as a problem-solving test based on Polya’s stages. Data analysis was conducted through data reduction, data display, and drawing conclusions interactively until the data were saturated. The results of the study showed that students with high self-efficacy scores were able to utilize mastery experiences, had stable self-confidence and expectations of success, were able to develop structured strategies, and could recover from failure with positive social support. These students also used the success of others as motivation in solving problems. In contrast, students with low self-efficacy scores showed less stable self-confidence, were more dependent on others for assistance, and had difficulties in developing effective problem-solving strategies. Their self-efficacy also tended to decrease easily when facing failure.
