Abstract

This research aims to analyze the ability of reflective thinking in mathematical problem solving among 9th-grade students of SMP Negeri 3 Tanjung, focusing on curved surface solids from the perspective of cognitive styles. The sample selection was carried out using a purposive sampling technique, resulting in 6 participants, consisting of 3 students with a field-dependent cognitive style and 3 students with a field-independent cognitive style. Data collection techniques employed in this study include the GEFT test, a test of reflective thinking ability in mathematical problem solving, interviews, and documentation. Data analysis was conducted using the Miles and Huberman model, involving data reduction, data presentation, and conclusion. The results of this study indicate that among the four indicators of reflective thinking ability in mathematical problem solving, specifically in the elaborating stage, students with a field-dependent cognitive style have not fully grasped the ability to plan and execute solutions. They struggle to comprehend more complex problems presented in narrative form, leading to difficulties understanding the concepts and executing the solution process. Conversely, students with a field-independent cognitive style have successfully fulfilled all four indicators across the three stages of reflective thinking ability. They tackle problems methodically and accurately, following planned steps following pre-established concepts.

Abstract

Mathematics, as a core subject, continually evolves to align with societal demands and technological advancements. Despite its essential role, challenges persist in mathematics education, particularly concerning students’ low interest and suboptimal academic achievement. Reports from UNESCO and international assessments such as PISA indicate that Indonesian students consistently perform poorly in mathematics. One contributing factor is the less effective utilization of instructional media by educators. Card-based learning tools have been identified as an effective strategy to boost students’ motivation and understanding of mathematical concepts. This study employs a Systematic Literature Review (SLR) approach to comprehensively examine the application of card media in mathematics instruction. A total of eight relevant studies were selected using specific inclusion and exclusion criteria. The findings indicate that card-based media, especially at the primary education level, significantly enhances students’ learning outcomes across various educational stages. Most of the analyzed research adopted the classroom action research model by Kemmis and McTaggart. The most frequently addressed topic was number concepts. On average, learning outcomes improved by 14.69% through the implementation of card media. These results suggest that card-based instructional media is a promising pedagogical tool that should be more widely adopted in mathematics classrooms.

Abstract

Statistical Literacy is needed by students in understanding information and presenting data in various forms of representation. This study aims to develop a mathematics module based on statistical literacy for junior high school students in the context of empowering Micro, Small, and Medium Enterprises (MSMEs) that is valid, practical, and effective. The research method uses a development research design with ASSURE stages. Twenty students of class VIII A were used as research samples, considering the ease and accessibility in conducting the research. Validity data were obtained through a validation questionnaire assessed by competent experts in their fields. Practicality data were obtained through a student response questionnaire. Effectiveness data were obtained based on the results of the statistical literacy pre-test and post-test. While observation data were used as supporting data to describe the module trial activities in learning. Quantitative data analysis used average values to analyze the results of the validation questionnaire and student responses, as well as the Wilcoxon test to determine the effectiveness of the developed module in learning. The validation results show that the developed module meets the validity criteria and receives positive responses from students and teachers. In addition, the Wilcoxon test results indicate the influence of module use in learning, that supported by the N-Gain test results of 0.59, indicating that the developed learning module is quite effective in improving students' statistical literacy. Although the development results are quite effective, students need to be accustomed to dealing with problems that contain the surrounding context, increase assignments, and integrate strategies, media, and learning models that focus on developing statistical literacy. Thus, the developed module has met the criteria of validity, practicality, and effectiveness. However, the results of the statistical literacy test evaluation indicate limitations in students' abilities to interpret and draw conclusions. This research provides an important contribution in developing relevant, innovative teaching materials, while highlighting crucial aspects for future learning, especially focusing on statistical literacy and contextual-based learning.    Keywords: statistical literacy, MSMEs empowerment, statistical module.

Abstract

This study explores the mathematical literacy challenges faced by students at SMK Negeri 2 Bawang, Banjarnegara Regency, in learning exponential concepts, which are analyzed through the lens of the Independent Regular Learning (SRL) level. Using a descriptive qualitative approach, this study involved three student subjects representing high, medium, and low SRL categories. Data was collected through mathematical literacy tests, SRL questionnaires, and interviews. The research findings indicate that variations in SRL levels significantly influence the types of difficulties students experience. Students with low SRL face various challenges, including understanding the context of the problem, building mathematical models, and interpreting results. Students with moderate SRL demonstrate the ability to understand problems but have difficulty selecting appropriate problem-solving strategies and accurately representing contextual situations in mathematical form. Meanwhile, students with high SRL exhibit systematic and reflective thinking but encounter obstacles connecting mathematical outcomes to real-life contexts. These findings underscore the role of SRL in shaping students' mathematical literacy challenges. Further research is recommended to investigate additional internal factors that influence mathematical literacy in order to develop more adaptive and targeted teaching strategies

Abstract

Creative thinking skills are students' ability to find ways or solutions that are unusual, unique, and have never been found by others in solving problems. This study aims to describe the ability to think creatively from the perspective of students' confidence. The research method used was qualitative descriptive, with data collection techniques through questionnaires, tests, and interviews. Questionnaires were used to divide the categories of student confidence, written tests were used to determine creative thinking skills in solving problems, and interviews were used to dig deep into information to obtain information related to problem solving. The subject of this study was sixth-grade VIII students of SMP N 1 Pekuncen. Subjects were grouped into three categories of confidence, namely high, medium, and low, based on the results of the questionnaire, using the purposive sampling technique; two people were taken as subjects in each category. The material used was a two-variable linear equation system. Data analysis techniques included data reduction, data presentation, and a conclusion drawn. The results of the study explained that (1) students with high categories were able to find solutions appropriately and could write down many ways to solve problems; (2) students in the medium confidence category could write down many ways to solve problems but couldnot find the right solution; (3) students with low confidence categories were not able to find the right solution and were unable to write down many ways to solve problems.

Abstract

Mathematical literacy is a crucial aspect of mathematics learning, yet it remains a significant challenge among students. While previous research has largely emphasized instructional approaches to enhance mathematical literacy, there is a lack of focus on the underlying difficulties faced by students, particularly in relation to self-regulated learning (SRL). This study aims to explore the problems in mathematical literacy encountered by vocational high school students at SMK Negeri 2 Bawang, Banjarnegara Regency, on exponential material, analyzed through their SRL levels. Employing a descriptive qualitative approach, the study involved three student subjects representing high, medium, and low SRL categories. Data collection was conducted using a mathematical literacy test, an SRL questionnaire, and interviews. The results indicate that variations in SRL levels significantly influence the types of difficulties students experience. Students with low SRL face extensive challenges, including understanding problem contexts, constructing mathematical models, and interpreting results. Those with medium SRL can comprehend the problems but struggle with selecting appropriate solution strategies and accurately representing contextual situations in mathematical forms. Meanwhile, students with high SRL exhibit systematic and reflective thinking yet encounter obstacles in connecting mathematical results to real-life contexts. These findings underscore the role of SRL in shaping students' mathematical literacy challenges. Further research is recommended to investigate additional internal factors affecting mathematical literacy to develop more adaptive and targeted instructional strategies.

Abstract

This study aims to describe the difficulties of students' critical thinking skills. The research method used was qualitative descriptive with data collection techniques through written tests and interviews. Written tests are used to find out students' difficulties in solving problems while interviews are used to dig deep into information to find out information related to problem solving. The subject of this study is grade VIII students of SMP Muhammadiyah Larangan. The material used is a straight line equation. Data analysis was carried out by triangulation, which is comparing data from sources (written tests and interviews). The results of the study showed that: 1) high category students did not experience difficulties in solving problems, namely interpreting, analyzing, solving problems, and conducting evaluations, but students experienced difficulties in making inferences or drawing conclusions; 2) Medium category students do not experience difficulties in interpreting, analyzing, and solving problems, but students have difficulties in conducting evaluation and inference. 3) Low-category students have difficulty in solving problems because students have difficulties in interpreting, analyzing, solving problems, evaluating and drawing conclusions in solving problems. Based on the results of the study, it shows that students are not used to solving contextual problems so that students need to be accustomed to working on contextual problems so that they do not experience difficulties in critical thinking.
