This study aims to describe the forms of mathematical misconceptions of students in solving contextual problems in fractional number material. The research used a descriptive qualitative approach and was carried out at SD Negeri 1 Gandasoli, Kuningan Regency. The subjects of the study were all students of class V totaling 39 people. Data was obtained through a written test in the form of contextual description questions about fractional numbers that have gone through the validity test stage. Based on the test results, students were classified into three levels of mathematical ability, namely high, medium, and low, then 9 students were selected as sample subjects for in-depth analysis. Data analysis is carried out through the stages of data reduction, data presentation, and conclusion drawn. The results of the study show that students still experience various types of mathematical misconceptions, including misconceptions of translation, signs, calculations, systematic, concepts, and strategies. Misconceptions of translation and signs were found at all levels of mathematical ability, while calculating, systematic, and conceptual misconceptions appeared in students of medium and low ability. Strategic misconceptions are only found in students with low mathematical ability. These findings show that the complexity of misconceptions increases as students' mathematical ability levels decrease, so learning that emphasizes understanding concepts and meaningful problem-solving in fractional number material is needed.

This study was conducted to explore the extent of the impact of students' critical thinking skills and mathematical connections in solving HOTS-type problems. Using a quantitative approach with a causal relationship model, this study took the subjects of grade VIII students at SMP Negeri 2 Sumber for the 2025/2026 school year period. From the total existing population, as many as 38 students were selected as a representative sample determined through the cluster random sampling method. All primary data were collected using a description test instrument that had passed validity and reliability tests to measure critical thinking competence, connection skills, and students' success in answering high-level questions. The data was then processed in depth through path analysis techniques with the help of SPSS 21 software.The main findings in this study reveal that critical thinking skills have a very strong direct influence on students' HOTS scores, which is evidenced by a beta value of 0.602 and a significance level of p < 0.001. However, quite contrasting results were found on the mathematical connection variable. This variable did not have a significant impact directly on students' ability to solve HOTS questions (beta = 0.115; p = 0.395). Furthermore, the results of the mediation test showed that no empirical evidence was found regarding the indirect influence of critical thinking on solving HOTS problems through the intermediary of mathematical connection ability. Simultaneously, the two independent variables tested in this model contributed 40.4% in explaining the variation in students' HOTS ability. This indicates that there are still around 59.6% of other factors outside of this study that also affect student achievement. In conclusion, these findings emphasize that the critical thinking factor is the most dominant and crucial element in supporting the success of junior high school students when facing complex mathematical problems.Pengaruh Kemampuan Berpikir Kritis dan Kemampuan Koneksi Matematis terhadap Kemampuan Siswa dalam Menyelesaikan Soal HOTSABSTRAKStudi ini dilakukan untuk mendalami sejauh mana dampak dari kecakapan berpikir kritis serta koneksi matematis siswa dalam menuntaskan soal-soal bertipe HOTS. Menggunakan pendekatan kuantitatif dengan model hubungan kausal, penelitian ini mengambil subjek siswa kelas VIII di SMP Negeri 2 Sumber untuk periode tahun ajaran 2025/2026. Dari total populasi yang ada, sebanyak 38 peserta didik terpilih sebagai sampel representatif yang ditentukan melalui metode cluster random sampling. Seluruh data primer dikumpulkan menggunakan instrumen tes uraian yang telah melewati uji validitas serta reliabilitas guna mengukur kompetensi berpikir kritis, kemampuan koneksi, dan keberhasilan siswa dalam menjawab soal-soal tingkat tinggi. Data tersebut kemudian diolah secara mendalam lewat teknik analisis jalur (path analysis) dengan bantuan perangkat lunak SPSS 21.Temuan utama dalam penelitian ini mengungkap bahwa kemampuan berpikir kritis memiliki pengaruh langsung yang sangat kuat terhadap perolehan skor HOTS siswa, yang dibuktikan dengan nilai beta sebesar 0,602 dan tingkat signifikansi p < 0,001. Namun, hasil yang cukup kontras ditemukan pada variabel koneksi matematis. Variabel tersebut justru tidak memberikan dampak signifikan secara langsung terhadap kemampuan siswa dalam menyelesaikan soal-soal HOTS (beta = 0,115; p = 0,395). Lebih lanjut, hasil uji mediasi menunjukkan bahwa tidak ditemukan bukti empiris mengenai adanya pengaruh tidak langsung antara berpikir kritis terhadap penyelesaian soal-soal HOTS melalui perantara kemampuan koneksi matematis.Secara simultan, kedua variabel independen yang diuji dalam model ini menyumbang andil sebesar 40,4% dalam menjelaskan variasi kemampuan HOTS peserta didik. Hal ini mengindikasikan bahwa masih terdapat sekitar 59,6% faktor lain di luar penelitian ini yang turut memengaruhi capaian siswa. Sebagai kesimpulan akhir, temuan ini mempertegas bahwa faktor berpikir kritis merupakan elemen yang paling dominan dan krusial dalam mendukung keberhasilan siswa tingkat menengah pertama saat menghadapi persoalan matematika yang kompleks.Kata Kunci:Kemampuan berpikir kritis matematis; kemampuan koneksi matematis; soal HOTS

Penelitian ini mengkaji bagaimana mahasiswa mengalami dan memaknai tahapan pemecahan masalah Polya saat mengerjakan tugas geometri dalam lingkungan electronic Problem-Based Learning (e-PBL) yang diimplementasikan melalui sistem manajemen pembelajaran berbasis Moodle yang dikustomisasi. Penelitian ini menggunakan desain deskriptif kualitatif dengan sumber data berupa artefak pemecahan masalah tertulis, wawancara semi-terstruktur, dan jejak digital selama e-PBL. Data dianalisis menggunakan analisis tematik Braun dan Clarke dengan pengodean deduktif berdasarkan empat tahap Polya dan pengodean induktif untuk menangkap pola penalaran yang muncul. Hasil penelitian menunjukkan bahwa pemecahan masalah berlangsung secara dinamis dan rekursif. Tahap memahami dan merencanakan melibatkan penafsiran ulang representasi multimodal, sedangkan tahap pelaksanaan ditandai oleh pergeseran representasi yang memperjelas konsep. Prompt reflektif dalam e-PBL mendukung deteksi kesalahan dan penguatan konsep, serta menegaskan peran tahap evaluasi. This study examines how students experience and interpret Polya’s problem-solving stages while working on geometry tasks in an electronic Problem-Based Learning (e-PBL) environment implemented through a customized Moodle based learning management system. Using a qualitative descriptive design, data were collected from written problem-solving artefacts, semi-structured interviews, and digital traces generated during e-PBL activities. The data were analyzed using thematic analysis following Braun and Clarke, combining deductive coding based on Polya’s four stages with inductive coding to capture emerging reasoning patterns. The findings indicate that problem-solving is enacted as a dynamic and recursive process rather than a linear sequence. Understanding and planning involve repeated reinterpretation of multimodal representations, while execution is characterized by representational shifts that support conceptual clarity. Reflective prompts in e-PBL facilitate error detection and conceptual consolidation, highlighting the importance of the evaluative stage.

Students often experience difficulties in representing mathematical concepts and communicating mathematical ideas clearly. This condition indicates that the learning model used needs to be reviewed and developed. This study aims to determine the effect of implementing the Discourse Multi-Representation (DMR) learning model on mathematical representation and mathematical communication abilities. The population was all class XI MA NU Putri Buntet Pesantren Cirebon. The sample was determined using the cluster random sampling method, consisting of two groups, namely the experimental and control classes. This study used a quasi-experimental design with a non-equivalent control group design. The research instrument was a test of mathematical representation and communication abilities arranged in the form of essay questions. The results of the t-test showed that for mathematical representation abilities there was no significant difference between the experimental and control classes. Conversely, for mathematical communication abilities, the use of the DMR model had an effect on students' mathematical communication abilities between the experimental and control classes.

The capacity for mathematical problem-solving constitutes a vital proficiency in mathematics education.Nevertheless, the proficiency level of Indonesian students in this domain remains suboptimal. Thisresearch endeavors to explore students’ perceptions of the integration of the Search, Solve, Create, andShare (SSCS) pedagogical model, augmented with bar modelling, and to evaluate its efficacy inadvancing their mathematical problem-solving competencies. Employing a quasi-experimentalframework with a non-equivalent control group design, the study utilized instruments such as a studentresponse questionnaire and a diagnostic assessment aligned with Polya’s problem-solving indicators.Findings reveal that student responses to the instructional approach fall under the “very good”classification, yielding an average score of 80.57%. Furthermore, the experimental group demonstrateda substantial enhancement in problem-solving capability, reflected in a normalized gain (N-Gain) of 0.79,while the control group exhibited a markedly lower N-Gain of 0.20. Results from the independentsample t-test produced a significance level (Sig. 2-tailed) of 0.000 < 0.05, indicating a statisticallysignificant divergence between the two cohorts. Consequently, it can be inferred that the SSCS model,when combined with bar modelling, serves as an effective and engaging instructional paradigm forbolstering students’ mathematical problem-solving aptitude.

This study aims to identify the influence of mathematical understanding and mathematical connection skills on students' mathematical representation skills. This study is motivated by the low level of students' mathematical representation skills, which is thought to be influenced by limited conceptual understanding and by difficulties connecting mathematical ideas. This study uses a quantitative, correlational design with a sample of class X-1 students at SMA Negeri 1 Arjawinangun. A total of 30 students were selected through cluster random sampling. Data were collected using a validated essay test to measure mathematical understanding, mathematical connection, and mathematical representation skills, and analyzed using multiple linear regression after meeting the classical assumption tests, including normality, multicollinearity, and heteroscedasticity. The results show that mathematical understanding and mathematical connection skills have a positive and significant influence on students' mathematical representation skills, both partially and simultaneously, where mathematical understanding (β = 0.484, p < 0.05) and mathematical connection (β = 0.298, p < 0.05) significantly contribute to the dependent variable. Furthermore, the two variables simultaneously explained 99.6% of the variance in students' mathematical representation skills (R² = 0.996), indicating a very strong predictive relationship. This finding highlights the importance of strengthening students' conceptual understanding and their ability to connect mathematical ideas to improve mathematical representation skills.
