Abstract

This research was conducted at SMP Negeri 7 Cirebon with quantitative methods. Quasi-Experimental research design in the form of posttest-only control group design. This research uses a purposive sampling technique to determine the research sample. The population in this study were all class VIII SMP Negeri 7 Cirebon. The samples used were class VIII B consisting of 36 students and class VIII D consists of 36 students. Data collection technique uses a test instrument in the form of a posttest in the form of a description. The results showed that there was a significant difference between the application of the double loop problem-solving learning model and the multi representation discourse learning model on students' mathematical problem solving abilities with a significance value of 0,001 less than 0,05 (< 0,05). This difference can also be seen from the results of calculating the average mathematical problem solving ability in the experimental class 1 which applies the double loop problem solving learning model of 75,89 while in experimental class 2 which applies the multi representation discourse learning model of 64,34. So, it can be concluded that the mathematical problem solving abilities of students who apply the double loop problem solving learning model are better than the mathematical problem solving abilities of students who apply the multi-representation discourse learning model to the Pythagorean theorem material

Abstract

Mathematical communication skills and mathematical representation skills are two important skills in mathematics learning. However, students' mathematical communication skills remain relatively low, so a study is needed to identify the factors that affect them, including mathematical representation ability. This study aims to examine the influence of mathematical representation skills on students' mathematical communication skills in grade VII C at SMP Al Washliyah Sumber. This study uses a quantitative approach with an explanatory correlational design and simple linear regression. The research sample consisted of 31 students selected through purposive sampling. The research instrument is in the form of a description test developed based on indicators of mathematical representation ability and mathematical communication ability, which have met the criteria for validity and reliability. The study's results show that mathematical representation ability has a positive, significant effect on students' mathematical communication skills. These findings suggest that students with good mathematical representation skills tend to have better mathematical communication skills. This research suggests that mathematics learning should facilitate the use of various forms of mathematical representation to improve students' mathematical communication skills.

Abstract

The low levels of mathematical literacy and problem-solving skills among Indonesian students, as reflected in the 2022 PISA results, underscore the need for an in-depth study of the factors influencing these two skills, one of which is self-efficacy. This study aims to describe the characteristics of students’ mathematical literacy and mathematical problem-solving skills in relation to their level of self-efficacy. The study employed a qualitative method with a descriptive approach. The research subjects consisted of 26 eighth-grade students from Class VIII G at MTs Negeri 3 Cirebon, selected through purposive sampling; subsequently, three students were chosen based on high, moderate, and low self-efficacy categories. Data collection was conducted using a mathematical literacy test instrument, a mathematical problem-solving test instrument, and a self-efficacy questionnaire. Data analysis utilized the Miles and Huberman model, which includes data reduction, data presentation, and drawing conclusions, and its validity was tested through triangulation of methods and sources. The results of the study indicate that students with high self-efficacy possess excellent mathematical literacy and problem-solving skills across nearly all indicators. Students with moderate self-efficacy exhibited an asymmetrical profile, showing weaknesses in the stages of understanding and formulating problems, yet strength in the planning and strategy implementation stages. Students with low self-efficacy demonstrated low ability across all indicators, with the most fundamental weaknesses in the stages of formulating problems and reviewing solution results. There is a consistent trend that the higher a student’s self-efficacy, the better their mathematical literacy and problem-solving skills. The problem-formulation and problem-understanding stages consistently emerge as the weakest points across all self-efficacy categories, thus requiring priority in the design of mathematics instruction.

Abstract

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

Abstract

This study addresses the limited development of students’ mathematical critical thinking ability in conventional classrooms and investigates the effectiveness of a flipped classroom supported by adaptive testing. The objective of this study is to examine the effect of this instructional approach on students’ mathematical critical thinking ability. An explanatory sequential mixed-methods design with a quasi-experimental pretest–posttest control group structure was employed, involving 64 students assigned to experimental and control groups. Data were collected through pre- and posttests, interviews, and classroom observations. Quantitative analysis using an independent samples t-test revealed a statistically significant difference in posttest scores, t(62) = 4.28, p < .001, with a large effect size (Cohen’s d = 1.07). The experimental group achieved a medium normalized gain (0.47), while the control group demonstrated a low gain (0.18). Qualitative findings indicated that students in the experimental group demonstrated more elaborated argument clarification, systematic process evaluation, relational inference and deduction, and strategic completion of missing information. In contrast, control group responses were predominantly procedural and recall-oriented. These findings suggest that the integration of flipped pedagogy and adaptive testing enhances higher-order reasoning processes and students’ mathematical performance, while adaptive testing is theoretically associated with more calibrated cognitive challenge and potentially more precise ability estimation.
