Abstract

This study was motivated by the low quality of Indonesian students' mathematical concept understanding, as shown by the PISA 2022 results, and by preliminary observations at SMP Mujahidin Pontianak indicating a relationship between the level of math anxiety and students' conceptual understanding ability. This study aimed to (1) describe the mathematical concept understanding ability of junior high school students experiencing math anxiety, (2) analyse the relationship between the level of math anxiety and mathematical concept understanding, and (3) identify the factors causing math anxiety among junior high school students. A descriptive qualitative approach was employed. The research subjects were eighth-grade students of SMP Mujahidin Pontianak in the 2025/2026 academic year, selected based on their level of math anxiety (high, moderate, and low). Data were collected through a questionnaire, a concept-understanding test on the topic of circles, and in-depth interviews, then analysed through data reduction, data display, and conclusion drawing/verification. The results revealed a consistent pattern: the higher the students' math anxiety, the lower their conceptual understanding, particularly on the interpretation and extrapolation indicators. Students with low anxiety demonstrated the most comprehensive understanding, those with moderate anxiety showed fairly good but inconsistent understanding, while students with high anxiety experienced serious cognitive obstacles. Three interrelated factors causing math anxiety were identified: personality (psychological/emotional), intellectual, and environmental/social factors, which jointly influenced the intensity of students' math anxiety. These findings suggest that teachers need to address the somatic, cognitive, and attitudinal dimensions of anxiety simultaneously while strengthening students' interpretation and extrapolation skills through supportive, anxiety-reducing instructional strategies.

Abstract

This study aims to develop teaching materials based on a deep learning approach assisted by the nearpod platform to improve students' problem-solving abilities in statistics material for class VIII SMP Negeri 16 Pontianak. This research is a Research and Development (R&D) research and development using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Data collection techniques include indirect communication techniques and measurement techniques, with research instruments in the form of expert validation sheets, practicality questionnaires, pretest and posttest questions. The research sample is class VIII A consisting of 29 students. Data analysis techniques used include analysis of characteristics, validity, practicality, and effectiveness of the developed teaching materials. The results of the study showed that the interactive learning media developed reached the very valid category with a validity percentage of 95.83%, very practical with a practicality percentage of 92%, and effective with the results seen from the results of the paired t-test showing that t_count is greater than t_table, namely 32.456 > 2.048 if t_count > t_table then Ho is rejected (H₁ is accepted). Thus, the developed teaching materials effectively improve students' problem-solving abilities. Thus, teaching materials based on the deep learning approach assisted by the nearpod platform are suitable for use in the mathematics learning process in schools

Abstract

This study aims to investigate the relationship between conceptual understanding and mathematical confidence in junior high school students in solving problems related to integer operations. This study involved 37 students who were measured using a quantitative approach through a descriptive correlational design. The instruments used included a test to measure conceptual understanding and a questionnaire to assess mathematical confidence. The results showed that most students had an adequate understanding of integer operations, although there were differences in their levels of mathematical confidence. Approximately 24% of students showed a very good understanding, while the other 32% obtained a good understanding. Correlation analysis showed a significant positive relationship between mathematical confidence and conceptual understanding, with a coefficient of r = 0.65, indicating that the higher the students' mathematical confidence, the better their understanding of integer concepts. Interviews with students also revealed that high levels of self-confidence encouraged them to be more active and confident in solving mathematical problems. Based on these findings, this study suggests that the development of students' mathematical confidence should be a primary focus in mathematics learning, through the implementation of problem-based learning methods and the provision of constructive feedback from teachers. Keywords: Conceptual understanding, Mathematical beliefs, integer operations, junior high school students, correlation.

Abstract

This research implements a qualitative descriptive method, which aims to analyze students' metacognitive abilities in terms of cognitive style in class VIII circle material at MTs Mathla'ul Anwar Pontianak. Data is collected and described in the form of words in descriptive research. This research was conducted at MTs Mathla'ul Anwar Pontianak. This research data was collected through certain methods, namely, tests, questionnaires, interviews which were used to analyze students' metacognitive abilities, then processed into clear and easy to understand information. The data sources in this research were 4 class VIII students at MTs Mathla'ul Anwar Pontianak. The data collection techniques used in this research are measurement techniques, direct communication techniques and indirect communication techniques with data collection tools in the form of test questions, questionnaires, interview guides and documentation. The data analysis techniques used are data reduction, data presentation, and drawing conclusions. The research results showed that in general subjects who had a field independent cognitive style showed better abilities in solving problems compared to subjects who had a field dependent cognitive style.
