Unravelling Affective Mathematical Disposition: Its Role in Strengthening Numeracy Among Pre-Service Mathematics Teachers
Get PDFThis study investigates the relationship between affective mathematical disposition (MD) and numeracy among pre-service mathematics teachers in Indonesia. The research examines explicitly how different dimensions of MD influence students' numeracy skills. A total of 237 participants took part in a semester-long numeracy enrichment program, followed by a numeracy assessment and an MD questionnaire based on Beyers' seven affective dimensions. Using multiple linear regression analysis, the findings indicate that MD significantly affects numeracy (p = 0.018), with an adjusted R-squared value of 0.571, indicating that 57.1% of the variance in numeracy scores can be explained by MD. Notably, the dimensions "Nature in Mathematics" (β = 0.584, p = 0.033) and "Mathematics Self-Concept" (β = 0.612, p = 0.016) exhibit significant positive influences on numeracy. Highlighting the role of conceptual understanding and self-perception in mathematical learning. These results align with the program’s design, which emphasized conceptual understanding and reflective self-assessment elements directly tied to both dimensions. However, other dimensions, including "Usefulness," "Worthwhileness," "Sensibleness," "Attitude," and "Math Anxiety," did not show significant effects. This may be due to participants' shared perceptions as mathematics teacher candidates, resulting in low variability on those dimensions, or due to possible mediation effects (e.g., motivation) that were not examined in this study. The findings suggest that interventions aiming to strengthen numeracy should focus on enhancing students’ understanding of mathematical structures and fostering a strong self-concept as mathematics learners. This study contributes to mathematics education by highlighting the specific affective dimensions that most directly relate to numeracy, providing a nuanced perspective for teacher educators seeking to balance cognitive and affective development in their curriculum.

The Effectiveness of Discovery, Inquiry, Problem, and Project-Based Learning in Mathematics Education: A Systematic Literature Review
Get PDFDiscovery-based learning plays a crucial role in enhancing students' mathematical understanding and critical thinking skills. This study analyzes the implementation of four major models Discovery Learning, Inquiry-Based Learning (IBL), Problem-Based Learning (PBL), and Project-Based Learning (PjBL) through a Systematic Literature Review (SLR) of 52 Scopus-indexed studies. The findings indicate that these models effectively improve conceptual understanding, higher-order thinking skills, and student motivation. Data from TIMSS (Trends in International Mathematics and Science Study) 2019 and PISA (Programme for International Student Assessment) 2022 confirm that countries consistently implementing these models demonstrate superior mathematical performance. The integration of technology, such as GeoGebra and e-learning platforms, further enriches learning experiences and enhances instructional effectiveness. However, challenges remain, including time constraints, uneven understanding of implementation, and difficulties in assessment design. This study reaffirms that discovery-based learning is an appropriate approach for 21st-century mathematics education. Recommendations include increasing research at the primary and secondary education levels, exploring artificial intelligence-based learning technologies, and developing more effective assessment strategies to support the implementation of this model across diverse educational contexts. Keywords: discovery-based learning, mathematics education, systematic literature review
Metacognitive Analogy Instruction: Effects on Students’ Reflective Thinking in Learning Biology
Get PDFThis study examined the effects of Metacognitive Analogy Instruction (MAI) on the students’ reflective thinking skills in Biology at the secondary level. A two-group pretest-posttest quasi experimental design was used to teach the control group using Non- Metacognitive Analogy Instruction (NMAI) which includes traditional way of teaching like lecture discussions, while the experimental group was taught using the Metacognitive Analogy Instruction. Results showed that students exposed to MAI improved better (M= 11.30) than those exposed to NMAI on the Habitual Action dimension (M= 10.09) of reflective thinking (p= 0.001) but the two groups had comparable performance (p= 0.42; 0.18; 0.09; & 0.10) on the Understanding (M= 14.40), Reflection (M= 12.47), and Critical Reflection dimensions (M= 12.73). The improvement of the MAI group in their overall reflective thinking skills scores particularly in the Habitual Action dimension could be attributed to the use of metacognitive analogies as part of the class instruction which required a considerable amount of focus and thinking. Hence, it is recommended that MAI be used for classroom instruction, curricular and instructional development, and teacher trainings to improve reflective thinking skills among students.

Content Analysis of Al-Islam and Kemuhammadiyahan Values on Multivariable Calculus Materials
Get PDFThe purpose of this research is to build a category of vector field material in Multivariable Calculus learning into the values of Al Islam and Muhammadiyah. The content analysis method uses MaxQDA to code the terms that emerge from the interview texts generated by the participants related to the intersection of the two subjects. The selection of participants is important in order to avoid bias in the description of the interview. Participants were selected 5 out of 31 students based on their knowledge of Multivariable Calculus material and experience in participating in organizational activities of the Muhammadiyah Student Association and the Orientation of Islamic Fundamentals. The results showed that there were three key categories, namely, death, hard work, and brotherhood. Since the vector principle is the same as the beginning of life and the final destination of a person, vector material is closely related to death. Likewise, integral material has a connection with hard work because the principle of line integral can be seen in line with the efforts made by someone. The vector field material is related to the theme of brotherhood because the principle of the vector field is in groups that can be seen as a collection of people. Keywords: vector field, islam, muhammadiyah, multivariable calculus. DOI: http://dx.doi.org/10.23960/jpmipa/v23i3.pp751-76
