This research aims to describe the development process and quality of STEM-based mathematics e-comics designed to enhance students’ creative thinking skills in flat-sided geometric materials for eighth-grade students at SMP. The study follows a Research and Development (R&D) approach using the ADDIE development model. The test subjects included a team of experts, a mathematics teacher, and eighth-grade students at SMPN 56 Merangin. The findings indicated a high level of validity, with the e-comics receiving a validity rating of 100% in terms of media and 95,24% in terms of material. The practicality rating from teachers was 100%, and it was classified as very practical. The overall practicality of the e-comics also fell under the “very practical” criteria. The effectiveness of the e-comics, as determined by an effectiveness questionnaire, scored 81,91%, which was considered “very effective.” Furthermore, a test yielded an N-Gain score of 0,65 categorizing the e-comics as quite effective. Based on the N-Gain score, it can be concluded that STEM-based mathematics e-comics effectively improve students’ creative mathematical thinking abilities.

In class X of SMA NEGERI 8 Muaro Jambi, a problem was found, namely that students' metacognitive abilities were still at a low level. Therefore, this study aims to describe and compare the impact of implementing the PBL and PjBL models on the level of students' metacognitive abilities in the SPLTV material. The research method used is True Experimental Design with a Pretest-Posttest Control Group Design research design . The population of this study was all students of class X of SMA Negeri 8 Muaro Jambi, with samples consisting of classes X Phase E1, X Phase E4, and X Phase E5. The instruments used to collect data were metacognitive ability level tests and learning implementation sheets. The results of the One-Way ANOVA analysis showed that there was a significant effect of the implementation of the PBL and PjBL models on the level of students' metacognitive abilities with a significance value of 0.002 < 0.05. Furthermore, the Tukey test showed that students who followed the PjBL model had a better level of metacognitive ability, with an average score of 36,53 compared to students who used the PBL model with an average score of 33,28 and conventional learning methods with an average score of 29,41.

This study aims to determine whether there are differences in the results of the influence of the application of the Creative Problem Solving (CPS) model, the Problem Based Learning (PBL) model and the Direct Instruction (DI) model in improving mathematical creative thinking skills in the material of quadrilaterals and triangles of class VII students of SMPN 9 Kota Jambi. Using an experimental posttest only control research design, this study involved the population of all class VII students of SMPN 9 Kota Jambi in the 2023/2024 academic year totaling 204 students from 7 classes. Through the Random Sampling technique , three classes were selected as samples, namely VII A, VII B, and VII C. Data collection was carried out using two instruments: observation sheets for the implementation of learning and evaluation tests for mathematical creative thinking skills. To analyze the collected data, statistical analysis using One way Anova showed a significance value of 0.000 which was smaller than 0.005. These findings indicate different effects of the application of the three learning models - CPS, PBL, and DI - on improving mathematical creative thinking skills. Posttest data showed that the group of students who received learning with the CPS model achieved an average score of 16.94, while the PBL group obtained an average of 16.26. Both groups showed superior results compared to the group using the DI (Direct Instruction) learning model

The learning techniques applied during the independent curriculum era require learning innovations that will be applied in learning, one of which is by implementing the PBL learning model and also the Inquiry model, where the application usually uses the direct instruction model. This study explains how the influence of students' mathematical literacy skills with the material taught, namely algebraic forms, with the learning model applied in each predetermined experimental class. True Experimental Design is a learning method used by researchers, Pretest-Posttest Control Group Design is the data obtained used by researchers. The results of the study found that the application of the inquiry learning model tends to provide a greater tendency towards students ' mathematical literacy skills compared to PBL and direct learning. In accordance with the results of the one-way ANOVA test and Tukey's follow-up test. The significant results obtained from the similarity test showed an increase in students' mathematical literacy skills, namely 0.727> 0.05. The hypothesis was found  accepted, with the results of the difference in the average influence of students' mathematical literacy test scores on the application of PBL, inquiry, and direct instruction learning models.

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.

Urgensi dalam penelitian ini didasarkan pada masih rendahnya kemampuan siswa dalam memecahkan suatu masalah, yang disebabkan karena penyajian soal yang jauh dari permasalahan kehidupan nyata serta kurangnya perhatian terhadap karakteristik belajar siswa yang beragam. Tujuan dalam penilitian ini adalah untuk melihat apakah penerapan pembelajaran berdiferensiasi dengan menggunakan problem based learning lebih efektif dalam meningkatkan keterampilan pemecahan masalah dari pada penerapan direct instruction yang selama ini diterapkan di sekolah. Di dalam penelitian ini menggunakan metode True Experimental Design dengan posttest-only control group design. Sampel terdiri dari dua kelas yang dipilih melalui teknik simple random sampling .Pengmpulan data dilakukan menggunakan tes posttest setelah perlakuan diberikan dan dianalisis menggunakan uji normalitas dan homogenitas serta dilanjutkan dengan uji T . Hasil yang didapatkan  menunjukkan bahwa nilai signifikansi yang di dapat melalui uji T berdasarkan sig. 1 tailed adalah sebesar < 0,001, yang mana nilai < 0,001 lebih kecil dari pada batas nilai signifikansi, yaitu 0,05. Hal ini membuktikan bahwa penerapan pembelajaran berdiferensiasi dengan model problem based learning lebih efektif dalam meningkatkan kemampuan pemecahan masalah matematis siswa dibandingkan dengan penerapan direct instruction. Selain itu, juga dapat ditunjukkan melalui rata-rata hasil posttest, yaitu di kelompok eksperimen memiliki rata-rata sebesar 30,27 sedangkan pada kelompok kontrol sebesar 25,00 Oleh karena   itu,   penilitian ini diharapkan memberikan solusi bagi guru untuk menciptakan pembelajaran yang efektif agar mampu meningkatkan keterampilan siswa dengan baik.

Hasil studi pendahuluan menunjukkan kemampuan berpikir kreatif siswa yang kurang dikembangkan dalam proses pembelajaran, sehingga salah satu solusinya melalui model Contextual Teaching Learning (CTL) dan Problem Based Learning (PBL) dengan open ended. Oleh karena itu penelitian ini memiliki tujuan untuk menyelidiki pengaruh terhadap kemampuan berpikir kreatif matematis siswa dengan menggunakan CTL dengan Open Ended dan PBL dengan Open Ended. Jenis penelitian ini metode eksperimen khususnya Posttest-Only Control Design dengan melibatkan siswa kelas VII SMPN 22 Kota Jambi, sementara teknik pengambilan sampel yang dilakukan yaitu cluster random sampling. Data yang dianalisis pada penelitian ini diambil dari lembar observasi keterlaksanaan kegiatan pembelajaran guru dan aktivitas yang dilakukan siswa yang diberi tanda ceklis oleh observer dan hasil skor hasil tes (posttest) kemampuan berpikir kreatif matematis siswa. Hasil uji asumsi yang dilakukan meliputi uji normalitas dengan nilai signifikansi  dan uji homogenitas dengan nilai 0,095. Selanjutnya hasil analisa ANOVA One Way diperoleh nilai signifikansi sebesar . Dengan demikian terdapat pengaruh yang signifikan dari model CTL dengan open ended dan PBL dengan open ended terhadap kemampuan berpikir kreatif matematis siswa. Kemampuan berpikir kreatif siswa jauh lebih meningkat saat diberikan perlakuan menggunakan model CTL dan PBL dengan Open Ended  dibandingkan dengan siswa yang diajarkan melalui metode pembelajaran langsung (Direct Instruction).

Literatur review ini menganalisis kemampuan pemecahan masalah matematika dan komunikasi matematik siswa dengan penerapan model Problem Based Learning (PBL) yang terintegrasi dengan etnomatematika. PBL, sebagai pendekatan pembelajaran yang berfokus pada pengalaman nyata, memungkinkan siswa untuk terlibat secara aktif dalam proses belajar melalui pemecahan masalah kontekstual. Di sisi lain, etnomatematika mengaitkan pembelajaran matematika dengan budaya lokal, meningkatkan relevansi dan motivasi siswa. Review ini mengkaji berbagai penelitian yang menunjukkan bahwa kombinasi PBL dan etnomatematika dapat meningkatkan keterampilan pemecahan masalah dan komunikasi siswa. Hasil menunjukkan bahwa siswa yang belajar dengan pendekatan ini lebih mampu menerapkan konsep matematika, berkolaborasi dalam kelompok, dan mengkomunikasikan ide-ide mereka secara efektif. Temuan ini menegaskan pentingnya integrasi konteks budaya dalam pembelajaran matematika untuk memfasilitasi pemahaman yang lebih mendalam dan keterlibatan siswa.
