Abstract

Completion of story problems by students needs to be profiled so that teachers can know the description or description of students' abilities in solving story problems. This study aims to obtain a profile of the completion of the circle tangent story problem by students of class IX E SMPN 5 Palu. This type of research is descriptive research with a qualitative approach. Data were collected through written tests and interviews. The results of this study showed that SH was able to do the problem correctly as the steps of solving the story problem. Then the results of EZ's solution show that there is an unfinished solution so that the answer obtained is wrong. Then the results of FR's completion showed that he was unable to solve the problem as the steps of solving the story problem so that the answer obtained was incorrect. Based on the results of this study, the researcher draws the conclusion that the profile of solving students' story problems varies based on students' mathematical abilities.

Abstract

Background: Mathematical problem-solving ability remains a major challenge among junior high school students, while empirical studies on the effectiveness of Problem-Based Learning (PBL) have reported inconsistent findings. Purpose: This study aims to synthesize evidence of PBL effectiveness on junior high school students’ mathematical problem-solving ability. Method: Through meta-analysis following PRISMA procedures, 14 eligible studies published between 2016 and 2025 were identified, while 11 studies used for further analysis. Comprehensive Meta-Analysis (CMA) software was used to determine effect sizes, heterogeneity, publication bias, and moderator variables. Findings: The results showed that PBL has a medium effect size (g = 0.569; p < 0.001) with stronger effect in Grade VIII, topics requiring HOTS, and during the COVID-19 studies. Heterogeneity was moderate, while publication bias and sensitivity tests confirmed results’ robustness. Implications: These findings support the use of PBL in mathematics learning to enhance students’ mathematical problem-solving ability across diverse classroom settings. Originality: This study contributes a quantitative synthesis of PBL effectiveness and highlights factors influencing its impact on mathematical problem-solving ability.

Abstract

Pelatihan penulisan modul ajar berbasis pengembangan Profil Pelajar Pancasila bertujuan untuk meningkatkan kompetensi guru dalam merancang dan menyusun materi pembelajaran yang sejalan dengan nilai-nilai Pancasila. Profil Pelajar Pancasila mencakup enam aspek utama: beriman dan bertakwa kepada Tuhan Yang Maha Esa serta berakhlak mulia, berkebhinekaan global, gotong royong, mandiri, bernalar kritis, dan kreatif. Melalui pelatihan ini, para peserta diharapkan dapat memahami dan mengimplementasikan konsep-konsep tersebut ke dalam modul ajar yang inovatif dan efektif. Pelatihan ini dilaksanakan melalui beberapa tahapan, yaitu pemaparan teori mengenai Profil Pelajar Pancasila, workshop penulisan modul ajar, dan sesi praktik serta diskusi kelompok. Metode yang digunakan mencakup ceramah, diskusi interaktif, dan pembimbingan langsung oleh fasilitator yang berpengalaman. Hasil dari pelatihan ini menunjukkan bahwa para guru mampu mengintegrasikan nilai-nilai Pancasila ke dalam berbagai mata pelajaran, sehingga dapat menciptakan lingkungan belajar yang lebih inklusif dan bermakna bagi siswa. Evaluasi pasca pelatihan menunjukkan peningkatan signifikan dalam kualitas modul ajar yang disusun oleh peserta. Dengan demikian, pelatihan ini memberikan kontribusi positif terhadap pengembangan pendidikan karakter berbasis Pancasila di SMP Negeri 2 Salomekko.
