The Indonesian Minister of Education and Culture implemented the Merdeka Belajar Kampus Merdeka Curriculum in 2019, emphasizing computational thinking (CT) as a crucial 21st-century skill. Despite its importance in mathematics education, most Indonesian mathematics learning has not been oriented toward developing computational thinking abilities. Vocational school students majoring in Software Engineering possess programming knowledge that could potentially enhance their mathematical problem-solving through computational approaches. However, the extent of their CT abilities when applied to mathematical contexts remains unclear. This study aims to describe and analyze the computational thinking abilities of 10th-grade vocational school students majoring in Software Engineering when solving quadratic function problems using Python programming language. This qualitative research employed a case study approach with three purposively selected students representing different proficiency levels (high, moderate, and low) based on standardized programming and mathematics assessment criteria. Data were collected through written tests, structured observations, and semi-structured interviews. The assessment focused on four CT components: decomposition, pattern recognition, abstraction, and algorithmic thinking. The analysis revealed distinct patterns in CT abilities across proficiency levels. High-proficiency students (S1) demonstrated systematic problem decomposition, optimal pattern utilization, effective information filtering, and efficient algorithm development, achieving an average CT score of 91.25. Moderate-proficiency students (S2) showed adequate CT abilities with some limitations in systematic organization and strategic thinking, scoring 78.75 on average. Low-proficiency students (S3) exhibited significant difficulties across all CT components, particularly in problem decomposition and algorithmic thinking, with an average score of 64.25. The findings indicate that students' mathematical foundations significantly influence their CT development when integrated with programming tools. The computational thinking abilities of 10th-grade Software Engineering students vary considerably when solving quadratic function problems with Python assistance. Students with stronger mathematical foundations demonstrate superior CT performance across all components, while those with weaker foundations require substantial scaffolding. These findings highlight the need for differentiated instructional approaches that consider students' varying CT development levels in mathematics education.

This study aims to describe the creative thinking abilities of Madrasah Tsanawiyah (MTs) students in solving problems in the material of one variable linear related to the level of mathematical anxiety. The approach used was qualitative descriptive involving three students from class VIII of MTs Al-Ibrohimi Gresik who were selected by purposive sampling based on low, medium, and high levels of mathematical anxiety. The research instruments included a mathematical anxiety questionnaire, a mathematical creative thinking ability test, and interview guidelines. Based on the results of data analysis, students with low anxiety levels showed fulfillment of the four indicators of creative thinking, namely fluency, flexibility, originality, and elaboration so that they were classified in the category of very creative. Participants with moderate anxiety met two indicators, namely flexibility and elaboration, which indicated a sufficient level of creativity. Meanwhile, students with high anxiety only met one indicator, namely flexibility, and were classified as less creative. The results of this study show a tendency to decline the ability to think creatively along with the increasing level of students' mathematical anxiety in the process of solving mathematical problems.

This study aims to analyze the creative thinking ability of junior high school students in solving mathematical problems on fractions material based on Polya's procedure. This research used a descriptive qualitative approach with the subject of two students who were selected purposively. The research instruments were problem solving questions based on Polya's four steps and interview guidelines to explore students' creative thinking processes. Data analysis was based on three indicators of mathematical creativity, namely fluency, flexibility, and novelty. The results showed that both subjects were able to understand the problem and identify relevant information, but there were differences in the problem-solving strategies used. The subject tends to use one conventional strategy without exploring other alternatives, so it has not met the indicators of flexibility and novelty. Meanwhile, the subject was able to generate several ideas and try various solution strategies, thus fulfilling the indicators of fluency, flexibility, and novelty. In addition, it was found that difficulties in understanding the concept and visual representation of fractions also affected students' creative thinking process. This finding confirms the importance of implementing open problem-based learning and systematic use of Polya's procedures to develop students' creative thinking skills, especially on fraction materials. The results of this study are expected to be a reference for teachers in designing mathematics learning strategies that are more innovative and according to the needs of students in junior high schools.

This study aims to analyze the creative thinking abilities of Junior High School students in solving open-ended mathematical problems. Creative thinking ability is an essential aspect of mathematics, particularly when solving problems that require varied solutions. This research employs a descriptive qualitative approach involving five seventh-grade students. Data were collected through open-ended problem-solving tests and interviews. The analysis was conducted by identifying indicators of creative thinking, such as fluency, flexibility, and novelty, based on students’ responses. The results show that students’ creative thinking abilities vary. Some students were unable to produce multiple different solutions (flexibility). Elaborating on their answers also posed a challenge for 60% of the students. This study provides implications for the development of mathematics learning that emphasizes enhancing students’ creative thinking abilities through open-ended problems.
