Abstract

Mathematical literacy is the ability that students must have to face 21st-century challenges. Related to this, students have learning styles that influence the way students absorb and process information, namely: Visual, auditory, and kinesthetic. This research focuses on describing the mathematical literacy of junior high school students in each indicator classified from the visual learning style. This type of research is descriptive qualitative research. The steps in this study were to compile the learning style questionnaire sheet and mathematical literacy tests; ask students to fill out questionnaires and ability tests; and analyze the results of the learning style questionnaire and student answers on mathematical literacy tests. The subject of the study consisted of 49 class VIII junior high school students, and then the subject was reduced to 6 students. The findings show that: 1) Students with visual learning styles have mathematical literacy in the range of levels 1 to level 2; 2) Visual students have characteristics of answering briefly and difficulty choosing words. The results of this study can be used as consideration in determining treatment in the teaching and learning process in class to increase student mathematical literacy.

Abstract

Current research indicates the presence of highly skilled and motivated students with robust computational thinking backgrounds seeking opportunities to leverage their expertise in driving innovation and success in this era. These studies also reveal that students' computational thinking skills vary widely depending on educational resources, curriculum emphasis, and individual aptitude. Nonetheless, there is a growing recognition of the importance of fostering these skills, with efforts underway to integrate them more comprehensively into education systems worldwide, including in Indonesia and Japan, as representatives of developing and developed countries. Therefore, assessing the competency of computational thinking in these two countries would be intriguing. The descriptive qualitative research method was employed to delineate the computational thinking competencies of students in Indonesia and Japan. Student worksheets, specifically designed for this purpose, were utilized to gauge the development of these competencies during the learning process using the Scratch application. The results revealed that students employed various strategies in solving the given geometry problems. On the other hand, geometry is one of the mathematics topics that can identify students' computational thinking using this application. These findings were utilized to categorize students' computational thinking skills in the two countries and to identify potential obstacles students experienced in their efforts to enhance these skills. Nevertheless, these constraints offer significant insights into potential areas for future investigation and enhancement. Subsequent endeavors could prioritize conducting experiments by implementing specific learning approaches or methods that have demonstrated effectiveness in improving students' computational thinking skills. This study not only underscores the potential for expanding research on students' computational thinking skills but also provides an overview of the learning process, learning culture, and students' competence in solving geometry problems with tiered difficulty levels using their computational thinking skills.

Abstract

This study investigates how the use of ICT tools can enhance students’ conceptual understanding of the area of a circle in a sixth-grade mathematics classroom. A six-lesson unit was designed integrating tools such as GeoGebra, Figma, a digital textbook, and Google Sheets. These tools supported different phases of learning from visual estimation and formula derivation to application and reflection. Students engaged in dynamic and collaborative tasks, which encouraged them to visualize geometric transformations, share strategies, and reflect on their understanding. Analysis of lesson observations and student reflections revealed three key learning outcomes: improved conceptual understanding through visual representations, increased strategic flexibility via peer interaction, and enhanced metacognitive awareness. The study highlights the importance of selecting and sequencing digital tools according to instructional goals, showing that well-orchestrated ICT integration can deepen mathematical thinking and promote active, reflective learning.
