Analysis of junior high school students critical thinking skills in solving contextual-based problems
No full textCritical thinking skills involve analysis, evaluation, and reasoning—essential abilities that students need to navigate the challenges of globalization. However, many students still lack adequate critical thinking skills. This is evident from the 2022 Program for International Student Assessment (PISA) results, which indicate that Indonesian students' PISA scores remain low. Contextual questions, as tested in PISA, can serve as an effective tool for measuring students' critical thinking abilities. This study aims to analyze the critical thinking skills of junior high school students in solving contextual-based mathematics problems, particularly those aligned with the PISA framework. The research employs a quantitative descriptive method, administering six descriptive questions on the topic of curved surface geometry to 37 ninth-grade students at SMP Negeri 12 Sukabumi City. The findings reveal that 11% of students exhibit high critical thinking skills, 30% demonstrate moderate skills, and 59% possess low skills. Students' responses indicate that they struggle to meet the five critical thinking indicators: identifying, clarifying, analyzing, evaluating, and inferring. Based on data analysis, it can be concluded that the critical thinking ability of students at SMP Negeri 12 Sukabumi City remains low, with 59% of students categorized in the low-skill group. This study contributes to the understanding of students' critical thinking deficiencies and highlights the need for improved teaching strategies to enhance these essential skills
Analysis of conjecture ability from the perspective of learning styles
No full textThis study investigates students' ability to make conjectures based on their preferred learning styles. A qualitative descriptive research methodology was applied. The participants consisted of ten mathematics majors enrolled in the 2024–2025 academic year. Researchers employed a purposive sampling strategy to select the subjects. The test questions and learning style surveys used in the assessment tool were reviewed and approved by expert educators. Data from the test and the learning style questionnaire were analyzed to determine students' learning styles and their ability to formulate conjectures. The results indicate that visual learners demonstrated the highest ability to make conjectures, as they tend to perceive mathematical concepts visually before solving problems. In contrast, students with auditory or kinesthetic learning styles exhibited lower conjecture-making abilities, primarily due to memory-related challenges. However, students with these learning styles can still improve their conjecture skills with appropriate instructional approaches. Enhancing students' ability to formulate conjectures enables them to better explain mathematical concepts, derive information from mathematical problems, anticipate outcomes, develop solutions, and construct well-founded arguments. This study contributes to the field of mathematics education by providing insights into how different learning styles influence students' conjecture-making abilities, which can inform the development of more effective teaching strategies
Mathematical literacy and learning style: An analysis of students’ PISA performance using Kolb’s framework
No full textThis study aimed to investigate the mathematical literacy of Grade VIII junior high school students based on their learning styles, as categorized by David Kolb. A qualitative approach with a descriptive research design was employed. The sample consisted of eight students, with two students representing each of the four learning styles: accommodating, assimilating, converging, and diverging. Data were collected through questionnaires, tests, and interviews. The research instruments included the Kolb Learning Style Inventory (KLSI), a mathematical literacy ability test, and an interview guide. Data analysis involved data reduction, data presentation, and conclusion drawing. The results revealed that students with accommodating and assimilating learning styles demonstrated proficiency in all three mathematical literacy indicators—formulate, employ, and interpret/evaluate—whereas students with a converging learning style met only two indicators (formulate and employ). In contrast, students with a diverging learning style fulfilled only one indicator (formulate). These findings suggest that students with accommodating and assimilating learning styles exhibited superior mathematical literacy skills compared to those with converging and diverging learning styles. This study contributes to the understanding of how different learning styles influence students' mathematical literacy and provides insights for educators to develop more effective teaching strategies tailored to diverse learning preferences
Development of similarity module based on ethnomathematics of Troso Jepara fabric motifs to improve numeracy literacy
No full textThis study aims to develop a similarity learning module based on ethnomathematics by raising the Troso Jepara fabric motif as a relevant local cultural context, and to examine the validity and practicality of the module in improving students' numeracy literacy. The ethnomathematics approach is used to integrate cultural values in mathematics learning, so that students not only understand the concept of similarity abstractly but are also able to relate it to everyday life. The research method used is the 4D development model (Define, Design, Develop, Disseminate), with a focus on the development and validation stages. For the Disseminate stage, this stage was not carried out. The instruments used include expert validation sheets and teacher and student response questionnaires. The results of the validation by experts obtained an average final score of 3.62, indicating that the module is in the very valid category with several suggestions for product revision, while the results of teacher and student responses obtained an average score of 3.36 indicating that the module is practical to use. Thus, this module can be an alternative contextual and meaningful teaching material in mathematics learning at junior high school level. The results of this study indicate that the developed learning module has met the criteria of being valid and practical for use. Through this study, teachers can integrate local cultural values into mathematics learning, which not only enriches the ethnomathematics approach but also supports the improvement of students' numeracy literacy. This module has a positive impact on students' ability to understand the concept of similarity and apply it relevantly in the context of local culture, so that learning becomes more meaningful and applicable
