Prior knowledge is one of the primary factors in the birth of ideas in computational thinking. Solving problems in the 21st century requires computational thinking skills. The computational thinking process involves abstraction, design, decomposition, algorithms, and verification. Research was conducted to describe students' computational thinking processes in solving contextual problems based on previous knowledge. The research process uses qualitative with an explanatory approach. A total of 40 students were grouped into low, medium, and high prior knowledge categories. One subject was taken in each category using purposive sampling. Tests and interviews were carried out for data collection. Data analysis consists of data reduction, presentation, and conclusions. The research results show that students in the high and medium prior knowledge categories wholly and correctly prove each computational thinking stage. Students can present problems visually, explain the flow of solution ideas used, write down the steps in detail and precisely, and check all solutions and final conclusions. Students in the low prior knowledge category need to improve at the design and algorithm stages—students' errors in interpreting the problem abstractly so that there is some misinformation. As a result, the completion steps and wrong results are obtained at the algorithm stage. The research results can be used to determine learning strategies in the classroom so that computational thinking skills increase.

Effective learning does not only aim to convey knowledge, but also to develop critical thinking skills that are important for students in facing various life challenges. Critical thinking skills enable students to analyze, evaluate and solve problems logically and independently. This article explores how contextual, open-ended and STEM learning approaches contribute to the development of students' critical thinking skills. Using the Systematic Literature Review (SLR) method, this research collected and evaluated journal articles from the Google Scholar database published between 2019 and 2024, focusing on these three approaches. The results of the analysis show that the contextual approach helps students relate the learning material to real situations, which enhances their understanding and application of knowledge. The open-ended approach encourages students to find multiple solutions and improve their analytical skills, while the STEM approach emphasizes the integration of disciplines to facilitate collaborative and creative learning. These three approaches are proven to be effective in improving students' critical thinking skills, which is reflected in their improved ability to identify, analyze and solve problems. This study provides important insights for educators and researchers to develop more effective learning strategies.

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.

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.

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.

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
