Abstract

Mathematical connection ability is one of the basic mathematics skills that must be possessed by junior high school students. It turns out that so far, the student's learning outcomes in terms of mathematics have not been encouraging. This study aims to describe the mathematical connection skills of junior high school students in solving a problem in terms of learning independence. This research is a qualitative descriptive study on eighth-grade students in a junior high school in Lamongan district, East Java. Data was collectied using test questions, interviews, and questionnaires. This study obtained the following results: 1) one subject (S2) who has high mathematical connection ability with low learning independence, 2) one subject (S1) who has moderate mathematical connection ability with moderately high learning independence, and 3) two subjects (S3 & S4) who have low mathematical connection skills with low learning independence. The internal causes of the lack of mathematical connection skills and student learning independence are the lack of practice questions, the lack of motivational stimulus to encourage students to study independently. While external factors are the level of test questions that are tested too difficult and the lack of supporting learning information sources

Abstract

The Effect of Interactive Media Based on Dynamic Geometry Software with the RME Approach on Improving Critical Thinking in Rotation Material. Objectives: The goal of this research is to examine the effect of using interactive media on Dynamic Geometry Software (DGS), like GeoGebra, along with the Realistic Mathematics Education (RME) technique in improving students’ critical thinking on the topic of rotation in geometry. Methods: The study used both a quantitative approach and a quasi-experimental approach. There were 38 students from SMA Negeri 1 Olahraga Sidoarjo in East Java who took part in this study. The experimental class and the control class consist of 19 students each. The experimental group learned with GeoGebra-based interactive media and the RME method, while the control group learned more traditionally without technology and the RME method. A set of validated test questions was administered before and after the intervention to measure students’ critical thinking skills. Results: There was a significant difference between the two groups’ critical thinking skills. Students in the experimental class were much better at understanding, evaluating, and thinking about geometric rotation problems than students in the control class. Combining GeoGebra and RME helped students understand how rotation works in real life and made them more interested, active, and better at understanding, exploring, and using it in a meaningful way. Conclusion: The RME method and GeoGebra helped students think critically about geometry, especially rotation. These results support the idea that using technology in a way that makes learning mathematics more meaningful, like RME, can help students think more deeply. Teachers should think about using these kinds of strategies to help their students learn mathematics better. Keywords: critical thinking, geogebra, quasi-experimental, RME, rotation.

Abstract

This study aims to identify the difficulties experienced by high school students in solving higher-order thinking skills (HOTS) questions on probability and to analyze the scaffolding provided to help students overcome these difficulties based on visual, auditory, and kinesthetic learning styles. HOTS questions require the students to think creatively, critically, and logically, which are commonly hindered by the abstract nature of the concept of probability. This qualitative descriptive study involved three students classified based on their learning styles. Data were collected using a learning style questionnaire, HOTS test questions, and interviews, and were analyzed via data reduction, data display, and conclusion drawing. The results showed that visual learners struggled with transformation and process skills, auditory learners with process skills, and kinesthetic learners with both transformation and process skills. To remedy these issues, scaffolding was created according to each learning style. Visual learners were assisted by the use of visual comparison charts and Figure-based guidelines, auditory learners responded to guided inquiry questions and oral explanations, and kinesthetic learners performed well through action tasks and movement-based simulations. These individualized scaffolding strategies allowed the students to overcome conceptual and procedural barriers, thereby improving their ability to answer HOTS probability questions more effectively. This study emphasizes the importance of adaptive support tailored to personal learning styles to increase the mathematical understanding of students.

Abstract

This study investigates the effectiveness of the Problem Based Learning (PBL) model assisted by GeoGebra in improving junior high school students’ learning outcomes on the topic of the System of Linear Equations of Two Variables (SPLDV). The research is grounded in the existing problems in mathematics classrooms, where students often experience difficulties in understanding abstract concepts, exhibit low problem-solving abilities, and show limited interest in learning due to conventional, teacher-centered instructional approaches. GeoGebra, as an interactive digital tool, provides dynamic visualizations that help students connect algebraic theory with graphical representation, thereby facilitating deeper conceptual understanding. The findings reveal that the implementation of PBL assisted by GeoGebra significantly enhances students’ conceptual understanding, problem-solving skills, and learning interest. These results suggest that integrating technology-supported PBL can create more meaningful and engaging learning experiences. The study recommends that future research extend the application of this model to other mathematical topics and educational levels, as well as examine its long-term effects on affective aspects such as motivation and learning attitudes.

Abstract

This study aims to develop a Hypothetical Learning Trajectory (HLT) based on student worksheets for teaching probability as an innovative approach to enhance students’ conceptual understanding. The development is driven by the need for instructional design that connects abstract mathematical concepts to real-life contexts. The research adopts a design-based research (DBR) approach through an in-depth case study of three eleventh-grade students. Data were collected through LKPD tasks, observations, semi-structured interviews, and diagnostic tests. Findings show that the HLT-based student worksheet effectively supported students’ progressive understanding of probability, fostering intuitive exploration and formal application. Students demonstrated active engagement, cognitive growth, and positive attitudes toward learning. The study concludes that implementing HLT through LKPD is a valid and promising strategy to improve the quality of mathematics instruction, particularly in the topic of probability.

Abstract

Penelitian ini dilakukan untuk menganalisis strategi guru dalam menerapkan permainan edukatif untuk mengelola dinamika kelompok dan juga menumbuhkan minat siswa dalam mempelajari matematika. Penelitian ini didorong oleh persepsi siswa bahwa matematika adalah mata pelajaran yang menakutkan dan membosankan yang mengakibatkan interaksi pasif dalam belajar kelompok. Penelitian ini menggunakan pendekatan kualitatif dengan tipe studi kasus dan subjeknya meliputi guru matematika dan juga siswa yang terlibat dalam pembelajaran kelompok. Pengumpulan data dilakukan melalui empat instrumen: wawancara, observasi aktivitas, tes prestasi belajar, dan juga studi dokumentasi. Teknik analisis data yang diterapkan adalah model interaktif Miles dan Huberman. Hasil penelitian menunjukkan bahwa penerapan permainan edukatif secara efektif mengubah dinamika kelompok dari pasif menjadi kolaboratif dengan nilai observasi rata-rata 3,14 (kategori Baik). Secara akademis, mayoritas siswa (72%) mencapai kategori Baik dan Sangat Baik. Hal ini juga menunjukkan bahwa permainan edukatif membantu membangun lingkungan sosial yang interaktif dan suportif (pembelajaran yang menyenangkan), yang secara bersamaan cenderung meminimalkan persepsi negatif dan juga meningkatkan antusiasme serta ketekunan siswa dalam belajar, sementara kebaruannya terletak pada peran permainan edukatif sebagai alat manajemen konflik dan juga penambah kekompakan kelompok, dan bukan hanya sebagai media penyampaian materi.

Abstract

This study aims to develop three types of assessments in mathematics learning for the Three Variable Linear Equation System material: initial, formative, and summative assessments. These three assessments are designed for use on a digital platform to enhance the efficiency of implementation and student involvement in the learning process. The study uses a Research and Development ( R&D ) approach with the ADDIE model consisting of five stages: analysis, design, development, implementation, and evaluation. The initial assessment in the form of a learning style questionnaire is distributed through Typeform to identify student learning characteristics. The formative assessment is designed in the form of an interactive quiz using the Nearpod application which includes multiple-choice questions. In the meantime, the summative evaluation is created as a context-based exam that gauges the knowledge, application, and reasoning dimensions. Four experts used Aiken's V test to validate the developed instrument, and Alpha Cronbach's reliability test was used to assess its dependability. With an Aiken's V > 0.80, the validation results demonstrate the instrument's high level of validity. The reliability test yields a moderately consistent Alpha Cronbach value of 0.45. The implementation's outcomes demonstrate that this technology-based evaluation can help identify student traits early on, offer feedback throughout the learning process, and measure learning success in a comprehensive way. Thus, creating this assessment could be a useful substitute for enhancing students' understanding of the Three Variable Linear Equation System.
