This study explores students' mathematical computational thinking ability in solving the Pythagorean Theorem problem. This research method used a qualitative approach with a phenomenological design. The subjects involved in this study were 12 junior high school students. Six students in grade 7 had not studied the Pythagorean Theorem, and six students in grade 8 were studying the Pythagorean Theorem. This study's results indicate several problems with students' mathematical computational thinking skills in mathematics learning. The first problem is seen from the aspect of abstraction. Students are given problems with the help of digital-based teaching aids. Then the researcher provides procedures containing questions so students can digest the information and follow their intuition to find a solution strategy. Still, students have not decided what information should be stored or ignored. The second problem is seen from the aspect of decomposition. Students have not been able to decompose complex problems into simpler and more manageable ones. Student responses are also still not according to the researchers' predictions. However, with the scaffolding technique, researchers can direct students' intuition or thought processes to focus more on the problem being asked. The third problem is seen from the aspect of generalization. Students have not been able to generalize the problem and have not been able to conclude from the steps that have been taken. These three problems indicate that students cannot recognize and identify patterns well, thereby reducing the efficiency of the mathematical problem-solving process.

Background: Educational disparities in Indonesia necessitate a comprehensive evaluation of students' critical thinking skills across various geographical regions, including highlands, border areas, and lowlands, to address potential educational shortcomings.Aim: The study aims to quantitatively assess and compare the mathematical critical thinking abilities of junior high school students across different geographical settings to inform educational strategies and interventions.Method: Employing a quantitative approach with an ex post facto causal comparative research design, the study utilized cluster sampling to select a representative sample of 82 students from highland, border, and lowland schools. Descriptive and inferential statistical analyses, including Kruskal-Wallis tests and post hoc examinations, were conducted to analyze the data.Result: Preliminary descriptive analysis indicated a general lack of critical thinking skills in mathematics among students in all areas. However, inferential statistical analysis revealed significant differences in the critical thinking abilities of students from the three geographical regions, with students in urban (lowland) areas displaying superior critical thinking rankings compared to their counterparts in border and rural (highland) areas.Conclusion: The findings underscore significant geographical disparities in mathematical critical thinking skills among Indonesian junior high school students. These disparities are likely influenced by factors such as unequal access to educational resources, teaching methodologies, student interest, and the socioeconomic and educational backgrounds of parents. Addressing these inequalities is crucial for enhancing the educational outcomes and critical thinking abilities of students across Indonesia.

The transformation from the 2013 Curriculum (K–13) to the Revised 2013 Curriculum (K–13R) in Indonesia represents a significant shift in mathematics education. This study aims to analyze the differences between K–13 and K–13R through six key aspects: (1) curriculum structure and competency formulation, (2) pedagogical paradigm including the implementation of Higher Order Thinking Skills (HOTS), (3) emphasis on literacy and numeracy, (4) teacher readiness and classroom implementation, (5) availability and contextual quality of textbooks and learning media, and (6) student learning outcomes based on PISA and national assessment data. Adopting a qualitative descriptive-comparative approach, this study uses document analysis to explore official curriculum guidelines, textbooks, and supporting literature. The findings reveal that K–13R introduces more structured and concrete competencies, increases focus on contextual and HOTS-based learning, and places greater emphasis on numeracy skills. Nevertheless, classroom implementation remains problematic due to gaps in teacher preparedness, lack of relevant instructional materials, and insufficient understanding of authentic assessments. These results highlight the need for integrated curriculum planning, sustainable teacher training, and contextual resource development to realize the intended transformation.

This phenomenological study investigates mathematics academic anxiety and pedagogical anxiety among pre-service elementary school teachers. Data were collected through in-depth interviews, questionnaires, and observations involving pre-service teachers in teaching practice. The findings reveal that most participants experience high to very high levels of anxiety, both as mathematics learners and as future educators. Academic anxiety is more dominant, often manifesting as negative thoughts, overthinking, and avoidance behaviors, while pedagogical anxiety is slightly lower due to a greater sense of control during teaching practice. The sources of anxiety are multifaceted, including internal factors such as lack of confidence and negative past experiences, as well as external pressures from the educational environment. These results highlight the urgent need for systematic interventions in teacher education programs, such as anxiety management training, self-efficacy workshops, and supportive learning environments, better to prepare pre-service teachers for the challenges of mathematics instruction. Despite its contributions, the study is limited by its cross-sectional design and focus on a single institution. Future research should consider longitudinal approaches and broader samples. Addressing mathematics anxiety among pre-service teachers is crucial for developing confident and competent mathematics educators, ultimately improving the quality of mathematics learning in elementary schools.

This study explored the differences in undergraduate students' concept images related to angles formed by a transversal intersecting any two lines compared with concept definition. Using diagnostic tests and interviews, the qualitative study with phenomenological design examined various student representations and common error patterns. Students' answers were analyzed qualitatively to identify patterns, misconceptions, and variations in their concept images, followed by semi-structured interviews to explore their justifications. Participants were 35 second-semester students from the mathematics education study program at a state university in Aceh, Indonesia, who had completed the plane geometry course. The findings revealed significant variations in students' concept images, which were: (1) pairs of alternate interior/exterior angles, corresponding angles, and same-side interior/exterior angles were formed when two parallel lines were intersected by a transversal; (2) the measure of corresponding angles must be equal; (3) the measure of alternate interior angles must be equal; (4) the measure of alternate exterior angles must be equal; (5) the measure of same-side interior angles must be equal; and (6) misunderstanding and incorrectly identifying alternate exterior angles. These results highlight the importance of adapting teaching approaches to address differences in concept images and to better support students in mastering geometric concepts. The novelty lies in its use of the Zone of Concept Image Differences to analyze the gap between students' concept images and formal definitions, offering insights into how to bridge these gaps in teaching.

Pendidikan karakter merupakan upaya untuk meningkatkan kualitas proses dan hasil pembelajaran yang mengarah kepada pembentukan karakter peserta didik dengan menitiberatkan pada keteladanan, pembiasaan, dan penciptaan lingkungan yaang kondusif. Bertujuan untuk menanamkan nilai-nilai karakter matematika seperti jujur, demokrasi, bertanggungjawab, mandiri, disiplin, kerja keras, kreatif, dan rasa ingin tahu. Nilai-nilai karakter yang dikembangkan dalam pembelajaran matematika tetap harus berlandaskan pada nilai-nilai universal. Pengintegrasian nilai-nilai pendidikan karakter dapat ditempuh dengan langkah-langkah : a) Menggunakan nilai-nilai budaya dan karakter yang memperlihatkan keterkaitan antara Kompetensi Inti dan Kompetensi Dasar dengan nilai dan indikator untuk menentukan nilai yang akan dikembangkan; b) Mencantumkan nilai-nilai budaya dan karakter itu ke dalam silabus; c) Mencantumkan nilai-nilai yang sudah tertera pada silabus ke dalam Rencana Pelaksanaan Pembelajaran; d) Mengembangkan proses pembelajaran peserta didik secara aktif yang memungkinkan peserta didik memiliki kesempatan melakukan internalisasi nilai dan menunjukkannya dalam perilaku yang sesuai; e) Memberikan bantuan kepada peserta didik, baik yang mengalami kesulitan untuk menginternalisasi nilai maupun untuk menunjukkannya dalam perilaku. Oleh karena itu diharapkan setiap peserta didik mampu menginternalisasikan nilai-nilai tersebut ke dalam tingkah laku kehidupan sehari-hari melalui proses pembelajaran, baik di dalam kelas maupun di luar kelas. Pembelajaran yang dapat menginternalisasikan nilai-nilai tersebut adalah pembelajaran kontekstual yang membantu guru dalam memotivasi siswa untuk mengaitkan pengetahuan yang dipelajarinya dengan kehidupan sehari-hari. Karakter apa sajakah yang dapat dikembangkan pada mata pelajaran matematika? Dan model pembelajaran apa yang dapat diterapkan untuk mengembangkan karakter matematika? Dengan menggunakan metode penelusuran literatur, artikel ini menyajikan tentang integrasi nilai-nilai karakter dalam mata pelajaran matematika melalui model pembelajaran kontekstual. Character education is an effort to improve the quality of process and learning outcomes that lead to the formation of the character of learners by focusing on exemplary, habituation, and the creation of a conducive environment. Aims to inculcate the values of mathematical characters such as honest, democratic, responsible, independent, disciplined, hard work, creative, and curiosity. The character values developed in mathematics learning must still be based on universal values. Integrating character education values can be pursued by the following steps: a) Using cultural values and characters that show the linkage between Core Competence and Basic Competence with values and indicators to determine the value to be developed; b) Include the cultural and character values into the syllabus; c) Include the values listed in the syllabus into the Lesson Plans; d) Develop an active learning process of learners that enable learners to have opportunities to internalize values and demonstrate them in appropriate behaviors; e) Provide assistance to learners, whether it is difficult to internalize the value or to show it in behavior. Therefore, it is expected that every student can internalize these values into the behavior of everyday life through the learning process, both in the classroom and outside the classroom. Learning that can internalize these values is contextual learning that helps teachers in motivating students to relate knowledge learned to everyday life. What are the characteristics that can be developed on math subjects? And what learning model can be applied to develop math character? Using the literature search method, this article presents the integration of character values in mathematics subjects through a contextual learning model.

Each student represents mathematical concepts uniquely. Therefore, this study aims to investigate how variations in students' learning styles impact their ability to solve divergent problems that measure their capacity in mathematical representation. This study utilized a one-way ANOVA test and quantitative methodology. A total of 23 eighth-grade students from one of the junior high schools in Bandung were sampled. They were selected on Tuesday, April 30, 2024, from 94 eighth-grade students using a simple random sampling technique. Learning style questionnaires and mathematical representation ability tests with divergent geometry and linear equation problems were used to collect data. The results showed that learning style, at the 5% significance level, affected symbolic mathematical representation ability yet it did not affect verbal or visual mathematical representation ability. Students with visual learning styles performed best when answering problems using symbolic mathematical representation ability, based on further investigation using post hoc tests.
