Analytical thinking enables students to solve complex problems in a systematic and measurable manner. This study examined students' analytical thinking processes in relation to self-efficacy using the Action-Process-Object-Schema (APOS) theory. The researchers employed a qualitative method with an explanatory approach. They selected mathematics education students from Universitas Muhammadiyah Purwokerto who were enrolled in a sequence convergence course as research subjects. To collect data, the researchers used analytical thinking tests, questionnaires, and interviews. Based on the self-efficacy questionnaire, the researchers classified students into high, medium, and low self-efficacy groups. They selected one informant from each category using purposive sampling. The data analysis involved three stages: data reduction, presentation of findings, and interpretation. The analytical thinking process included collecting, differentiating, organizing, and attributing. The findings showed that students in the high and medium self-efficacy groups demonstrated strong analytical thinking skills. They successfully completed all stages—collecting, differentiating, organizing, and attributing. In contrast, students with low self-efficacy lacked adequate prior knowledge and required assistance in applying mathematical concepts and completing proofs during the organizing stage. These students gathered only limited information at the collection stage due to a poor understanding of the main problem. As a result, they could only partially complete each stage of the analytical thinking process. Keywords: analytic thinking process, APOS theory, self-efficacy.

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.

The research outlines the computational thinking process that prospective mathematics teachers use to solve PISA model problems. The Department of Mathematics Education conducted the research on 32 students in the Basic Mathematics course. This qualitative approach research used research instrument such as a computational thinking skill test and interview guidelines. The researchers grouped students into low, medium, and high ability categories based on previous tests. The researchers took as many informants as possible from each category using purposive sampling techniques. The applied technical data analysis included data reduction, presentation, and conclusions. The computational thinking process consisted of orientation, abstraction, decomposition, algorithms, and evaluation. The study provided several results, including high- and medium-category students being able to write information at the orientation and algorithm stages. The difference between the computational thinking processes of low- and medium-category students lies in the orientation stage and algorithms. Low-category students had to be more detailed in recording every step of the problem-solving process, as they could not write down all the primary information and problems. Those three lied in the orientation stage, the process of identifying information, and the key problems at the orientation stage as an early and important aspect of the computational thinking process. This research facilitates teachers improve students' computational thinking in solving high-level problems. Keywords: computational thinking process, PISA model problems, problem-solving DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp961-971
