This experimental research with a quantitative approach will test several learning models on students' mathematical problem solving abilities. The models used are CTL and PBL. This study involved three sample classes including CTL, PBL and Direct Instruction classes. In each learning model, the differences between the three will be examined to see their influence on students' mathematical problem solving abilities. The quantitative analysis used is the Tukey test with a significance level of 0.981. Meanwhile, the direct learning model shows a significance value of 0.024, which means there is no significant influence. Thus, the PBL and CTL learning models have more influence on mathematical problem solving abilities than direct instruction.

This study aims to describe students' metacognition in solving PtLSV problems regarding field-independent and field-dependent cognitive styles. This research was conducted at SMP Negeri 1 Muaro Jambi in the 2023/2024 academic year. This type of research is qualitative research. The subjects of this study were 4 students of class VIIA of SMP Negeri 1 Muaro Jambi, 2 students each with field-independent cognitive style and field-dependent cognitive style. Data collection methods were the results of the GEFT test to determine students with field-independent and field-dependent cognitive styles , PtLSV problem-solving questions, unstructured interviews and documentation. Data analysis techniques consisted of data collection, data reduction, data presentation and conclusion. The results showed that students with field-independent cognitive style met all indicators of metacognitive activity in problem-solving. However, students with field-dependent cognitive style did not meet the metacognitive evaluation indicators in re-checking the results, and errors were seen in operating PtLSV problem-solving. The second student with a field-dependent cognitive style, he only met the metacognitive activity indicators in understanding problems but did not yet have a strategy in solving PtLSV problem-solving questions.

This study aims to analyze the forms of students’ critical thinking failures in solving problems on the topic of Systems of Linear Equations in Two Variables (SPLDV) based on their levels of self-efficacy. This research employed a descriptive qualitative approach involving three eighth-grade students from SMPN 15 Muaro Jambi, selected through purposive sampling to represent high, medium, and low levels of self-efficacy. Data were collected through a critical thinking test based on the FRISCO indicators, in-depth interviews, observation of students’ cognitive processes, and documentation of their problem-solving steps. The findings indicate that students’ critical thinking abilities are still not optimal, particularly in the indicators of Reason, Inference, and Overview. Students with high self-efficacy demonstrated good understanding of the context and were able to construct mathematical models accurately, but they were still weak in interpreting results and reflecting on their solutions. Students with medium self-efficacy made algebraic reasoning errors and failed to evaluate the reasonableness of their answers. Meanwhile, students with low self-efficacy experienced difficulties across all stages, including understanding the context, selecting appropriate strategies, and evaluating their final solutions. These results reveal that differences in self-efficacy levels significantly influence the quality of students’ critical thinking processes. This study highlights the need to strengthen both cognitive and affective aspects to enhance students’ critical thinking skills in mathematics learning. Keywords: critical thinking, FRISCO, self-efficacy, SPLDV, mathematics education

Pembelajaran fisika di Sekolah Menengah Atas (SMA) seharusnya dilaksanakan dengan penggunaan media dan kegiatan eksperimen yang optimal untuk membangun pemahaman konseptual dan keterampilan berpikir ilmiah. Namun di wilayah Muaro Jambi, guru-guru fisika SMA masih menghadapi kendala dalam memanfaatkan media dan alat praktikum yang tersedia, baik karena keterbatasan pelatihan maupun persepsi bahwa eksperimen membutuhkan banyak waktu dan memerlukan peralatan canggih. Tujuan dari kegiatan pengabdian ini adalah melatih dan mendorong guru untuk mengoptimalkan penggunaan media dan alat praktikum dalam pembelajaran fisika. Kegiatan pelatihan dilaksanakan pada tanggal 11 September 2025 di SMA Negeri 3 Muaro Jambi yang diikuti oleh 12 guru fisika dari enam Sekolah Lanjutan Tingkat Atas (SLTA) di wilayah tersebut. Kegiatan menggunakan pendekatan partisipatif yang menggabungkan metode diskusi, demonstrasi, dan praktik langsung dalam merancang media sederhana serta eksperimen berbasis inkuiri seperti pada topik listrik dan beberapa topik fisika lainnya. Hasil menunjukkan bahwa seluruh peserta mampu mengidentifikasi potensi alat yang selama ini tidak termanfaatkan, mengembangkan minimal satu media pembelajaran kontekstual, dan merancang lembar kerja siswa berbasis eksperimen. Kegiatan ini membuktikan bahwa penguatan kapasitas guru melalui kemitraan perguruan tinggi dan sekolah dapat menjadi strategi efektif dalam meningkatkan kualitas pembelajaran sains di daerah.

This study is based on the low level of students' HOTS abilities at SMP Negeri 14 Kota Jambi, as well as the continued dominance of conventional teaching models. Based on this, the purpose of this study is to examine the use of Problem-Based Learning (PBL) and inquiry learning models combined with a contextual teaching and learning to improve ninth-grade students’ HOTS skills on the topic of Systems of Linear Equations in Two Variables. The research employed a posttest control group design. All ninth-grade classes constitute the population in this study. The samples included class IX F, which was taught using the PBL model with a real-life-based approach; class IX E, which used the inquiry learning model with a real-life-based approach; and class IX D as the control class, which applied a conventional learning model. Data were collected through observation sheets to assess the implementation of teacher and student activities, as well as through a posttest instrument measuring HOTS abilities. The results showed differences among the classes using the PBL model with a real-life-based approach, the inquiry model with a real-life-based approach, and the conventional model. The average posttest scores in the experimental classes I and II were 6.25 and 6.43 (high), while the control class only achieved an average score of 1.96 (low).

In learning activities, of course students cannot be separated from mathematical problems which are focused on efforts to train students' thinking patterns in using their thinking potential. Apart from that, learning Mathematics aims to equip students with solving skills problem, Literacy Numeracy, logical, reasoning, abstract, systematic and creative. Facts in the field, researchers found problems with students' metacognitive abilities in Field Dependent and Field Independent learning styles based on information processing theory. This research is a type of qualitative research that uses descriptive research methodology. These subjects were selected using purposive sampling (purposeful sampling). This research was conducted at SMP-IT Ash-Shidiqi Batanghari in the odd semester 2022/2023. The subjects were 4 research subjects. The instrument used in this research was the GEFT (Group Embedded Figures Test) to find students' learning styles including the filed category dependent or filed independent, after that students are given a test question sheet. Then, based on the question sheet, the researcher conducted interviews to research subjects. The data obtained were analyzed using steps (1) transcribe data obtained from think aloud and interviews, (2) reduce data, (3) coding data, and (4) describing information processing on students' metacognitive abilities in linear equations and inequalities material linear one variable. Based on the results of the research and analysis that has been carried out, it can be concluded that students' metacognition in solving problems consists of four indicators, namely Tacit use (use of thinking without awareness), Aware use (use of thinking with awareness), Strategic use (use of strategic thinking) Reflective use (use reflective thinking).
