Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dan peningkatan menggunakan model problem based learning terhadap keterampilan berpikir kreatif fisika siswa. Penelitian ini dilakukan pada siswa kelas X SMA. Variabel pada penelitian ini adalah keterampilan berpikir kreatif dan model Problem-Based Learning. Instrument penelitian menggunakan test dalam bentuk essay dengan jumlah 7 soal yang telah dinyatakan valid. Hasil uji analisis covariate menunjukkan lebih kecil dari 0,05, yang berarti terdapat perbedaan keterampilan berpikir kreatif yang diajarkan menggunakan model PBL. Model Problem-Based Learning meningkatkan keterampilan berpikir kreatif lebih baik dibandingkan pembelajaran konvensional. Penggunaan model PBL dapat meningkatkan keterampilan berpikir kreatif kecuali pada indikator berpikir flexibility.

Abstract

This research aims to determine the effect of the STEM-based project-based learning (PjBL) model on class XI students' problem-solving abilities in sound wave material. This type of research is quasi quasi-experiment with a two-group pretest-posttest design. This research sample consisted of two classes: class XI IPA 7 as the control class and XI IPA 9 as the experimental class. The instrument used is a problem-solving ability test in the form of a description that has been validated. Based on the research results, the average pretest and posttest scores in the control class were 43,58 and 67,45, and the experimental class average was 40 and 75. Based on the results of hypothesis testing using the difference test (t-test), sig (0.004) < 0.05 was obtained. Based on the N-gain test, it was obtained that the percentage increase in students' problem-solving abilities in the experimental class was 89% in the high category, and in the control class was 64% in the medium category. Based on statistical data, it can be concluded that there is an influence of implementing the STEM-based PjBL model on students' problem-solving abilities in sound wave material.

Abstract

The Guided Inquiry (GI) model has been extensively applied in science education to foster Higher Order Thinking Skills (HOTS), yet systematic evidence of its effectiveness across educational levels in Indonesia remains limited. This study conducted a narrative systematic literature review (SLR) of 20 studies (11 experimental/quasi-experimental, 4 meta-analyses, and 5 systematic reviews) published between 2019 and 2025, aiming to evaluate the effectiveness of GI in improving HOTS—critical thinking, creative thinking, and problem solving—as well as Science Process Skills (SPS) in Indonesian elementary, junior high, and senior high school science contexts. The review followed PRISMA guidelines and involved database searches in Portal Garuda, SINTA, Google Scholar, Scopus, ERIC, and Web of Science, using relevant keywords. Inclusion criteria required studies to focus on GI in science learning, report HOTS or SPS outcomes, and be published in reputable Indonesian or international journals. Study quality was assessed using adapted JBI Critical Appraisal Tools. Meta-analytic findings revealed very large effect sizes for critical thinking (g = 1.33), creative thinking (g = 1.10), and problem solving (g = 1.31), while experimental studies showed high-category SPS gains (N-Gain = 0.7) and improved scientific literacy. GI effectiveness was consistently high at the junior and senior high school levels (effect size 0.8–1.3), but varied at the elementary level (0.4–1.10), depending on scaffolding intensity and implementation duration. Integration with technology and STEM contexts led to superior outcomes. The review concludes that GI is highly effective in enhancing HOTS and SPS across levels, though effectiveness depends on adaptive scaffolding and learning conditions. Limitations include study heterogeneity and potential publication bias.

Abstract

This study aims to see the effect of project-based learning (PjBL) integrated with the STEAM approach (Science, Technology, Engineering, Arts, and Mathematics) on students' critical thinking skills on static fluid material in grade XI of high school. The research employed a quasi-experiment with a two-group pretest–posttest control group design. The sample consisted of two classes, namely class XI MIA 2 (experimental group) and class X MIA 1 (control group), which were selected using a simple random sampling technique, with each class consisting of 36 students. The research instrument used was an essay test designed to assess students' critical thinking skills. The data were analysed using a t-test to determine the differences between groups. Pretest results indicated comparable initial critical thinking abilities between the experimental and control groups. However, following the implementation of STEAM-integrated PjBL, the experimental group demonstrated a significant improvement in post-test scores compared to the control group. This improvement was reflected in a higher percentage increase in critical thinking skills, indicating the positive impact of the integrated approach. The effectiveness of this intervention was further supported by a high score on the relative effectiveness test, emphasizing its value in enhancing critical thinking skills. These findings suggest that active, interdisciplinary learning strategies can effectively enhance students' analytical and problem-solving abilities, better preparing students for real-world challenges through deeper engagement and creative thinking.

Abstract

This study aims to determine the significant effect of the argument driven inquiry (ADI)-STEM learning model on numeracy literacy and scientific argumentation skills of students on the subject matter of dynamic fluid class XI semester II at SMAN 10 Medan T.P 2024/2025. This type of research is a quasi experiment and the research design is a two-group pretest-posttest. The population in this research is the entire class XI of SMAN 10 Medan T.P 2024/2025. The sample in this study consisted of two classes selected randomly with simple random sampling technique, class XI IPA-1 as an experimental class using argument driven inqiry (ADI)-STEM learning model with a total of 36 students and class XI IPA-2 as a control class with conventional learning model with a total of 31 students. The instrument in this study was a test in the form of a 10 question essay. Data analysis was used with manova test. The results of the study were obtained with the average value of the numeracy literacy pretest of the experimental class and control class 53.89 and 54.19 respectively while the scientific argumentation of the experimental class and control class 52.22 and 51.68 respectively. The average post-test scores of numeracy literacy of experimental and control classes were 83.22 and 71.48 respectively while scientific argumentation of experimental and control classes were 86.78 and 70.90 respectively. Data analysis using manova test concluded that there is a significant effect of argument driven inquiry learning model on numeracy literacy and scientific argumentation
