The study aims to describe the creative thinking process of junior high school students with different Adversity Quotient (AQ) categories (quitter, camper, and climber) in solving numeracy problems. This qualitative research involves three subjects representing distinct AQ categories. Data collection includes the ARP questionnaire, numeracy problem-solving tests, and interviews, with analysis using the Pierce sign concept. Findings reveal camper and climber subjects effectively separate information in the ideation stage, while quitter and climber subjects associate knowledge concepts in generating idea. In preparing a plan for application, camper and climber subjects strategize based on information and knowledge, while in applying an idea, quitter subjects surrender, campers choose easier alternatives, and climbers persist with pre-planned strategies. Results suggest tailored motivation according to students' AQ categories can enhance teacher-student engagement.

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 used a 14-year-old male student whose criteria were not to be blind from birth without any other defects. A hard blow to the head back is caused the student's disability. Pupils with disabilities no longer attend regular primary school from IV class onwards. This study aims to determine the process of pictorial representation of right triangles based on information processing models. This type of research is descriptive and explorative with a qualitative approach. This study uses the main instrument and the supporting instruments. Here, students are asked to perform mathematic assignments and then interviewed, and all activities performed are analyzed using observation sheets. Data analysis was performed with three activities: data condensation, data presentation, and conclusion and verification. The results of the study show that blind students can make pictorial representations. Creating images can be seen in students' activities in completing mathematical assignments. Information or external stimuli enter the sensory register through the senses of hearing and touch, after which attention and perception arise. Perception by retrieving the necessary concepts from long-term memory. When retrieving process, students experience moments of forgetting, and then they repeat the parts of a right-angled triangle until they finally have a correct right-angled triangle.
