Abstract

This study aims to analyze the content validity of summative assessment items in Combinatorics that are aligned with the Minimum Competency Assessment (MCA) framework. The study was motivated by the need for valid and high-quality assessment tools that support meaningful and sustainable mathematics learning. This study employed a research and development (R&D) design but it focuses primarily on the Develop stage, which aims to obtain a valid summative assessment instrument. The Aiken’s V method was used to measure the content validity of nine multiple-choice items developed according to the MCA numeracy domains, cognitive levels, and contexts. Three mathematics education experts served as validators. The analysis showed that the Aiken’s V indices ranged from 0.64 to 0.73, indicating medium validity. These results suggest that the instrument can be used after minor revisions. The validated instrument provides a reference for educators to design MCA-oriented summative assessments that enhance students’ mathematical literacy and reasoning skills. Future research may apply other validation methods such as Gregory’s analysis to strengthen the evidence of validity.

Abstract

Mathematics education is looking for innovative methods to foster problem-solving skills in students. This research develops a problem-solving assessment using GeoGebra Classroom, a versatile interactive mathematics software, to revolutionize mathematics formative assessment and improve students' problem-solving skills. This study adopted the analysis, design, development, implementation, and evaluation (ADDIE) instructional design model stages. The design stage created a comprehensive assessment blueprint, incorporating GeoGebra Classroom functions to create interactive problem-solving tasks. Data analysis used both quantitative and qualitative approaches. Qualitative data consisted of feedback and suggestions from assessment experts, mathematicians, and GeoGebra specialists. Meanwhile, quantitative data included expert scores and cognitive tests that measured students' problem-solving abilities. A cognitive post-test was conducted to measure the progress of students' understanding while using the assessment product. The results of the content validity analysis, assessed using Aiken's V, ranged from 0.85 to 0.92, indicating a high level of validity for the problem-solving skills assessment in terms of content and construction. Some revisions were made to the design of the developed media to make it more interactive for students. These findings suggest that we can further use problem-solving questions integrated with GeoGebra Classroom to uncover the problem-solving skills of junior high school students.

Abstract

The Iceberg Design framework has been utilized to represent the progression of students’ mathematical understanding, moving from informal, contextually grounded reasoning toward formal mathematical abstraction. This study investigates how prospective mathematics teachers develop Iceberg Designs within the Realistic Mathematics Education (RME) framework, a model that enhances contextual learning and supports mathematical literacy. Thirty prospective mathematics teachers from Universitas Negeri Surabaya participated in this qualitative study, collaboratively designing Iceberg models as part of their coursework. Data from document analysis, interviews, and observations were evaluated using content analysis, the research evaluated the depth and coherence of their designs across four key components: situational contexts which evaluates the relevance and variety of real-world situations, model-of representations which examines the assistance of mathematical representation to connect the context into mathematical concept, model-for abstractions which assess the use of mathematical models toward formalization, and formal mathematical concepts which assess the mathematical ideas being explicitly involved. The findings reveal significant variation in the quality and completeness of the Iceberg Designs. Models for equivalent ratios and quadratic equations exhibited strong integration, using multiple, varied contexts to bridge situational and formal mathematical understanding effectively. Conversely, designs for fraction multiplication and quadrilateral area conservation were often surface level, relying on a single, underdeveloped context that hindered abstraction. Importantly, the study underscores the potential of Iceberg Designs to support the Sustainable Development Goals (SDGs), particularly in fostering critical thinking, practical problem-solving, and meaningful contextual learning for high quality of education (SDG 4) and decent work for sustainable economic growth (SDG 8). These insights indicate the need for deeper integration of RME principles in teacher education and curriculum development through sustained investment in this area.

Abstract

Mathematics anxiety is one of the obstacles experienced by students in the learning process and has an impact on decreased motivation and academic achievement. This study aims to examine the role of collaborative learning as a solution to overcome mathematics anxiety. This study uses a Systematic Literature Review (SLR) approach with data collection through the SINTA and Google Scholar databases. Based on the established inclusion and exclusion criteria, six relevant scientific articles published between 2019 and 2025 were identified. The results of the study indicate that collaborative learning models such as Problem-Based Learning, Teams Games Tournament (TGT), Student Teams Achievement Division (STAD), Group Investigation, Fan-N-Pick, and Heroe's consistently reduce students' math anxiety levels. The commonality among these models lies in creating an active, enjoyable learning environment that supports positive social interaction among students. By encouraging students' emotional and intellectual engagement, collaborative learning has proven effective in enhancing self-confidence and mathematical concept understanding. Therefore, optimizing the implementation of collaborative learning tailored to students' characteristics is recommended as a pedagogical strategy to improve the quality of mathematics education and reduce learning anxiety across various educational levels.

Abstract

Problem posing is important in learning mathematics because it improves reasoning, critical thinking, and creative thinking skills. However, many students still find it difficult to pose problems. Through collaborative problem posing, students can exchange their understanding. The use of GeoGebra in problem posing can help students play an active role in generating ideas to construct new problems through its features. This research is a qualitative research that aims to describe the collaborative semi-structured problem posing of junior high school students assisted by GeoGebra in high groups. This research was conducted in one of the junior high schools in Surabaya class IX odd semester of the 2024/2025 school year in the age range of 14-15 years. The research data were collected through Problem Posing Test and Focus Group Discussion. The research subjects were a group with high mathematical ability consisting of two students. The results showed both members in the group contributed to each other for the new problem created. On knowledge base, they identified mathematical facts, concepts, and procedures. On heuristics and schema, they explored GeoGebra to come up with ideas. On group dynamics and interactions, they performed processes of normality, conformity, and innovation. In individual consideration of aptness, both members argued that each individual was skilled in proposing problems and the problems they created were acceptable to group members. Student had no problems during discussion and expressing their opinions due to their equal mathematical ability. Therefore, further research is needed on whether collaborative problem posing using GeoGebra heterogeneous groups also works. ABSTRAK Pengajuan masalah merupakan hal penting dalam belajar matematika karena meningkatkan kemampuan penalaran, berpikir kritis, dan berpikir kreatif. Namun, masih banyak siswa merasa kesulitan dalam pengajuan masalah. Melalui pengajuan masalah kolaboratif siswa dapat saling bertukar pemahaman. Penggunaan GeoGebra dalam pengajuan masalah dapat membantu siswa berperan aktif memunculkan ide-ide untuk mengkonstruksi masalah baru melalui fitur-fiturnya. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mendeskripsikan pengajuan masalah semi terstruktur kolaboratif siswa SMP berbantuan GeoGebra pada kelompok tinggi. Penelitian ini dilakukan di salah satu SMP di Surabaya kelas IX semester ganjil tahun ajaran 2024/2025 pada rentang usia 14-15 tahun. Data penelitian dikumpulkan melalui Tes Pengajuan Masalah dan Focus Group Discussion. Subjek penelitian merupakan kelompok dengan kemampuan matematika tinggi yang terdiri atas dua siswa. Hasil penelitian menunjukkan kedua anggota dalam kelompok saling berkontribusi untuk masalah baru yang dibuat. Pada basis pengetahuan, mereka mengidentifikasi fakta, konsep, dan prosedur matematika. Pada heuristik dan skema, mereka mengeksplorasi GeoGebra untuk memunculkan ide-ide. Pada dinamika dan interaksi kelompok, mereka melakukan proses normalitas, konformitas, dan inovasi. Pada pertimbangan individu atas kesesuaian, kedua anggota saling berpendapat bahwa tiap individu terampil dalam mengajukan masalah dan masalah yang mereka buat dapat diterima anggota kelompok. Siswa tidak memiliki masalah selama berdiskusi dan mengungkapkan pendapat dikarenakan kesetaraan kemampuan matematika. Oleh karena itu, perlu penelitian lebih lanjut terkait apakah pengajuan masalah kolaboratif pada kelompok heterogen berbantuan GeoGebra juga berjalan demikian.

Abstract

Mathematical skills and ability are indispensable in the 21st century, especially in the development of modern technology. Thus, an understanding of mathematics is necessary to face future challenges. Unfortunately, math is often perceived as a big challenge by students, especially in affective aspects such as math anxiety. This anxiety is known to have a negative impact on students' performance, working memory, and mathematical ability. Therefore, this study aims to determine how much influence Collaborative Problem Based Learning has in reducing math anxiety. Through post-test data, this study uses quantitative, quasi-experimental methodology. The population is class 10 students in a high school in Gresik Regency (N = 320). By purposive sampling, two classes (64 students) studying Two-Variable Inequality System material were selected, which were divided into experimental groups with CPBL treatment and control groups with conventional learning. This research instrument was modified from Sadia Mahmood and Tahira Khatoon's Mathematics Anxiety Development Instrumen (14 items). The results showed that the application of the CPBL learning model did not have a significant effect on reducing student anxiety. This may be due to the short implementation period (two meetings), inconsistent group collaboration, and and a lot of students are hesitant to seek clarification when they are having trouble understanding algebra.
