Abstract

Critical thinking is vital for learning statistics in mathematics. This study aims to evaluate the critical thinking abilities of eighth-grade students at Muhammadiyah Pakem Junior High School by considering their learning styles in the context of statistics. This qualitative research involved two students selected through purposive sampling as research subjects from each learning style: visual, auditory, and kinesthetic. Data were collected via questionnaires, tests, and interviews. The data processing techniques applied included data presentation, data reduction, and conclusion drawing. The research findings indicate that: (i) students with a visual learning style demonstrated exceptional critical thinking skills, aligning with the indicators of interpretation, analysis, evaluation, and inference; (ii) students with an auditory learning style exhibited strong abilities in evaluation, analysis, and inference, although their interpretation skills were not fully developed; and (iii) students with a kinesthetic learning style possessed good skills but had not yet fully met the indicators of analysis and evaluation. Furthermore, students with a visual learning style were considered more proficient in critical thinking, as they were able to explain visual representations of mathematical concepts before solving problems. On the other hand, auditory and kinesthetic learners still have the potential to further develop their critical thinking skills.

Abstract

Character education is an increasingly prominent aim of contemporary schooling, yet the processes by which culturally and religiously grounded extracurricular programs shape student character remain under-examined in non-Western contexts. This qualitative case study examines how participation in Tapak Suci, a Muhammadiyah martial arts extracurricular activity, contributes to character formation at a private senior high school in Yogyakarta. Information was collected from 12 students, 4 coaches, and 2 school administrators via 18 semi-structured interviews, 40 hours of participant observation, and document analysis conducted between March and May 2025. Analysis followed Miles and Huberman’s interactive model with systematic thematic coding and triangulation across sources. Findings indicate that Tapak Suci supports the development of religious commitment, discipline, punctuality, responsibility, mutual respect, and self-control. These outcomes were sustained through regular training routines, explicit moral instruction, coach role-modelling, and organizational rituals that integrate practice with moral discourse. The study clarifies mechanisms by which extracurricular practice translates into enduring character dispositions and discusses limits to transferability given the single-site design. Implications include the value of aligning extracurricular structure with explicit character objectives and of training coaches as intentional character educators. This research contributes empirical evidence from an understudied cultural context and offers actionable recommendations for educators seeking to harness extracurriculars for character education.
