Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah siswa dalam menyelesaikan soal cerita materi segi empat berdasarkan indikator kemampuan pemecahan masalah. Subjek penelitian ini adalah siswa kelas VIII-1 MTs. Nurul Bahri Kabila Bone. Pengambilan data dimulai dengan memberikan tes kemampuan pemecahan masalah matematika dan dilanjutkan dengan wawancara Hasil penelitian menunjukkan bahwa Subjek dengan kemampuan tinggi mampu memahami masalah, menyusun rencana, dan memeriksa jawaban dengan cermat. Namun, mereka terkadang kurang lengkap dalam mencatat informasi yang diketahui dan ditanyakan. Secara keseluruhan, mereka menunjukkan kemampuan pemecahan masalah yang sangat baik. Subjek dengan kemampuan sedang dapat memahami masalah dan merencanakan solusi dengan baik, tetapi seringkali kurang lengkap dalam menyusun model matematika dan langkah-langkah penyelesaian. Mereka juga kesulitan memeriksa hasil pada soal yang lebih kompleks. Subjek dengan kemampuan rendah mengalami kesulitan dalam memahami soal, menyusun rencana pemecahan, dan melakukan perhitungan dengan tepat. Banyak langkah yang terlewat, dan mereka kesulitan memahami konsep matematika dasar. Dengan demikian bahwa tingkat kemampuan seseorang memengaruhi kualitas pemecahan masalah matematika.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan penalaran proporsional siswa SMP dalam menyelesaikan masalah perbandingan langsung dan terbalik yang ditinjau dari gaya belajar lapangan independen (FI). Metode penelitian yang digunakan adalah deskriptif dengan pendekatan kualitatif. Data dikumpulkan melalui tes penalaran proporsional dan wawancara. Subjek penelitian adalah enam siswa kelas tujuh SMP Negeri 1 Botupinge tahun ajaran 2025/2026, yang dipilih secara purposif berdasarkan tingkat kemampuan tinggi, sedang, dan rendah serta memiliki kecenderungan gaya belajar FI. Data dianalisis secara kualitatif dengan memperhatikan indikator pemahaman kovariasi, pemikiran relatif, dan penyediaan penalaran konseptual. Hasil penelitian menunjukkan bahwa siswa dengan kemampuan tinggi menunjukkan penalaran proporsional yang kuat dan konsisten di hampir semua indikator. Siswa dengan kemampuan sedang mampu menyelesaikan masalah secara prosedural, tetapi pemahaman konseptual mereka belum stabil. Sementara itu, siswa dengan kemampuan rendah belum menguasai penalaran proporsional dan cenderung menyelesaikan masalah secara mekanis tanpa memahami hubungan antar besaran. Temuan ini menunjukkan bahwa kecenderungan independensi bidang berkaitan dengan variasi kemampuan penalaran proporsional siswa, dan siswa dengan kemampuan sedang dan rendah membutuhkan intervensi pembelajaran yang lebih terstruktur. Kata kunci: Penalaran proporsional, perbandingan, independen bidang, kemampuan siswa, kualitatif

Abstract

This study aims to enhance the motivation and learning outcomes of high school students at SMA Negeri 7 Gorontalo for the 2022/2023 Academic Year through implementing android-based learning media on temperature and heat materials. The research method is a quasi-experimental design with a one-group pretest-posttest research design. The research sample consisted of 3 classes: class X IPA 2 as the experiment class and class X IPA 3, and X IPA 4 as a replica class. This research begins with preparing learning tools to implement learning media based on Android material on temperature and heat. The results of the validation show that the learning tools are valid and can be used in the learning process. Implementing the learning process in this study is in the very good category. It can increase student motivation and learning outcomes, where the N-Gain scores for the experimental and replica classes are in the high category.

Abstract

This research is a development research (Research and Development) which aims to determine the validity, practicality and effectiveness of developing a Project Based Learning (PjBL) science learning module on additives and addictive substances. This research uses the ADDIE model up to the stage (Analysis, Design, Development, Implementation and Evaluation) and was tested in class VIII SMP Negeri 7 Telaga Biru with a one group pre test-post test design. The results showed that: (1) The developed module obtained an average of 3.66 with a valid category obtained through the validity test; (2) The developed module is practical as indicated by the learning is very well implemented with an average percentage of 92% and students state that the learning process using the Project Based Learning-based Science learning module is practical to be applied in the classroom; (3) The developed module is effective as indicated by students who are active in learning for three meetings with an average percentage of 85% (good category), the increase in student learning outcomes for the cognitive domain reaches an N-gain value of 0.71 including in the high category. Based on the results of this study, it can be concluded that the learning module developed is of high quality.

Abstract

This study aims to investigate the application of the Problem-Based Learning (PBL) model in minimising students’ errors in learning mathematics within the statistics curriculum. The research method employed was Classroom Action Research (CAR). The research was conducted at SMKN 1 Bonepantai during the second semester of the 2024/2025 academic year, with a sample of 25 Year 11 students comprising 11 male and 14 female students. Data collection was carried out through observation and tests of students’ mathematical learning errors. The research consisted of two cycles. The results of the study indicate that the application of the Problem-Based Learning (PBL) model can minimise students’ mathematical learning errors in statistics. In Cycle I, the percentage of conceptual errors was 57%, operational errors 73%, and principle errors 61%. Following improvements to the teaching approach in Cycle II, the percentage of student errors decreased to 50% for conceptual errors, 65% for operational errors, and 51% for principle errors. This represents a reduction of 7% in conceptual errors, 8% in operational errors, and 10% in principle errors. Furthermore, the results of observations of teacher and student activities in Cycle II reached 100%, with ratings of ‘good’ and ‘very good’.

Abstract

This study aims to determine the effect of using the Problem-Solving learning model on students' Creative Thinking Ability with Number Patterns. This study involved 40 students as the research sample consisted of two classes, every 20 students in class A and 20 students in class B. The research method used was Experimental research with Pretest-Posttest Control Group Design. The data collection technique was obtained through the pre-test and post-test results, and the data analysis technique used the covariance analysis test. The analysis results show that the creative thinking ability of students who are taught using the Problem-Solving model is better than the creative thinking skills of students trained using the direct learning model.
