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

The low percentage of numeracy proficiency among junior high school students, as reported in the 2024 Indonesian Education Report, emphasizes the importance of high-quality numeracy questions equivalent to the Minimum Competency Assessment as effective practice materials to enhance students' numeracy skills. This study aims to analyze the characteristics of numeracy questions equivalent to the Minimum Competency Assessment delivered through the Jotform platform for junior high school students. The items are developed as online practice materials aimed at familiarizing students with solving numeracy problems in accordance with the standards of the national competency assessment. This research is an exploratory study using a quantitative approach. The primary data were collected from the result of 20 numeracy items distributed through Jotform to 27 students enrolled in the eighth grade of a privacy secondary school located in Surabaya. Four analyses were conducted to examine the item characteristics: validity, reliability, difficulty index, and discrimination index. Findings indicate that the average validity of the items falls within the moderate level, the reliability in categorized as high, the average difficulty index is also in the moderate range-suggesting the items are effective for evaluating students’ numeracy skill-and the average discrimination index demonstrates an excellent classification. In light of the results, the questions are considered appropriate for use in online numeracy practice.

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.
