Abstract

Developing critical thinking in physics is a priority in 21st-century education, yet evidence comparing the effectiveness of different instructional approaches—particularly those integrating problem-based learning (PBL) with digital quiz platforms—remains limited. This study compared the effects of three learning models—PBL assisted by Zep Quiz, Zep Quiz alone, and traditional lecture—on 11th-grade students' critical thinking skills in mechanics. A counterbalanced within-subject quasi-experimental design was employed with 102 students from SMAN 4 Tangerang Selatan. Each student experienced all three models across three topics (Newton's Laws, Momentum & Impulse, Rotational Motion) in a rotated order. Critical thinking was measured using a validated 18-item test based on Facione's six indicators (reliability: 0.78–0.79 for two topics, 0.45 for Rotational Motion). Data were analyzed using N-gain, repeated-measures ANOVA, and ANCOVA with pretest scores as covariate. All models improved critical thinking with moderate-to-high N-gain (0.73–0.78). Repeated-measures ANOVA showed significant differences between models (F(2,202)=4.920, p=.008, η²=.046). However, after controlling for pretest scores, ANCOVA revealed no statistically significant differences between models (F(2,202)=2.229, p=.109, η²=.015, small effect). Topic characteristics explained substantially more variance (η²=.642) than model variations (η²=.015). The largest gains occurred in Momentum & Impulse (N-gain=0.89), the lowest in Rotational Motion (N-gain=0.55). The three learning models are comparably effective in improving critical thinking in mechanics. Topic characteristics—particularly conceptual complexity—outweigh model variations in determining learning gains. Physics educators should prioritize alignment between instructional design and topic demands rather than focusing solely on model selection. Future research should extend to other physics topics and investigate longer-term retention.

Abstract

Students have difficulty understanding physics concepts because they cannot connect them with everyday life. As a result, they study concepts separately and do not understand the relationships between concepts, especially on the topic of renewable energy, which are interconnected and play an important role in future life. This study aims to analyze the influence of the STEM-based Project-Based Learning model on students' system thinking abilities. A quantitative approach was used with a quasi-experimental design in the form of a Nonequivalent Control Group Design. The sample consisted of 62 tenth-grade students divided into experimental and control classes. The experimental class received the PJBL-STEM treatment, while the control class used the Problem Based Learning model. The highest improvement was observed in the coherent indicator, while the lowest improvement was in the intermediate indicator. These findings indicate that PJBL-STEM is effective in enhancing students' system thinking abilities, with an N-Gain value of 0.76 in the high category. This research is beneficial as an alternative learning strategy that can develop students' thinking skills and contribute to designing learning that is relevant to students' real-life contexts.

Abstract

ABSTRACT The concept of Green building is one of our efforts to maintain environmental and natural conditions so that they are not damaged and are in good condition. The building sector in Indonesia has a considerable contribution, especially in energy consumption, water consumption, land use, and several other problems that have the potential to have an impact on the environment, for this reason, it is necessary to apply a green building concept. Moreover, currently Indonesia is intensively improving infrastructure for the construction of public buildings. So it is hoped that the application of the green building concept to public property can be an effort to face climate change. This paper discusses the application of the concept of building to public property as an effort to face climate change. The study took a sample at the Jakarta International Stadium where with a literature review based on case studies with descriptive methods. Keywords : Green building, Public property, Climate change, Jakarta International Stadium ABSTRAK Konsep Green building merupakan sebagai salah satu upaya kita untuk menjaga kondisi lingkungan dan alam supaya tidak rusak dan berada di dalam kondisi yang baik. Sektor bangunan di indonesia memiliki kontribusi yang cukup besar terutama dalam konsumsi energi, konsumsi air, pemakaian lahan, dan beberapa masalah lainnya yang memiliki potensi berdampak terhadap lingkungan, untuk itulah perlunya menerapkan suatu konsep bangunan hijau (green building). Terlebih saat ini Indonesia sedang gencar meningkatkan infrastruktur pembangunan bangunan umum. Sehingga harapannya penerapan konsep green building pada public property ini dapat menjadi upaya menghadapi climate change. Tulisan ini membahas tentang penerapan konsep building pada public property sebagai upaya menghadapi climate change.

Abstract

Kemampuan berpikir kritis merupakan salah satu kompetensi esensial yang perlu dikembangkan dalam pembelajaran fisika. Namun, pembelajaran fisika masih didominasi oleh hafalan rumus dan penyelesaian soal secara prosedural sehingga pemahaman konseptual dan kemampuan berpikir kritis siswa belum berkembang secara optimal. Kondisi tersebut menunjukkan perlunya pendekatan pembelajaran yang mampu memberikan pengalaman belajar yang bermakna. Penelitian ini bertujuan menganalisis pengaruh penerapan model Experiential Learning berbantuan audiobook terhadap kemampuan berpikir kritis siswa pada materi suhu dan kalor. Penelitian menggunakan metode kuasi eksperimen dengan desain counterbalance pretest-posttest control group. Sampel dipilih menggunakan teknik purposive sampling yang melibatkan 64 siswa kelas XI di salah satu SMA Negeri di Jakarta. Data dikumpulkan menggunakan tes kemampuan berpikir kritis dan dianalisis menggunakan normalized gain (N-gain), uji Mann–Whitney U, dan effect size Cohen's d. Hasil penelitian menunjukkan bahwa penerapan model Experiential Learning berbantuan audiobook menunjukkan tingkat efektivitas yang berbeda pada materi suhu dan kalor. Pada materi kalor diperoleh perbedaan yang signifikan antara kelompok eksperimen dan kontrol (p = 0,003; Cohen's d = 0,757), sedangkan pada materi suhu perbedaannya belum signifikan (p = 0,066) meskipun memiliki effect size kategori sedang (Cohen's d = 0,502). Temuan ini menunjukkan bahwa model Experiential Learning berbantuan audiobook efektif dalam mendukung pengembangan kemampuan berpikir kritis siswa dengan efektivitas yang bervariasi sesuai karakteristik materi. Penelitian selanjutnya disarankan menggunakan instrumen dengan jumlah butir soal yang lebih banyak serta durasi intervensi yang lebih panjang agar pengukuran kemampuan berpikir kritis dapat dilakukan secara lebih mendalam.

Abstract

Conventional quasi-experimental designs in physics education are prone to bias due to differences in characteristics between classes, order-of-instruction effects, and the influence of prior treatments. This study introduces and demonstrates a balanced 3×3 Latin Square design as an alternative methodological framework to enhance internal validity in physics education experiments based on in Indonesia. Using a quasi-experimental rotation at SMAN 4 South Tangerang (N = 102; three 11th-grade classes), each class received three instructional treatments in rotation: (A) Problem-Based Learning (PBL) aided by Zep Quiz, (B) Zep Quiz without PBL, and (C) conventional lectures, on three subtopics of Dynamics of Motion. Students’ critical thinking skills were assessed using an instrument based on Facione’s six indicators. Data were analyzed using prerequisite tests (Shapiro-Wilk, Levene, Mauchly), Repeated-Measures ANOVA, Latin Square ANOVA, and a carryover effect test. Three main findings emerged: (1) a significant period effect (p = 0.028, η² = 0.035) indicated a gradual increase in scores over time; (2) the class factor accounted for the majority of the variance (F = 153.051, p < 0.001, η² = 0.736), far exceeding the effect of the learning method (F = 0.678, p = 0.058, η² = 0.005); and (3) the carryover effect was not significant (F = 0.000, p = 1.000), confirming the effectiveness of rotation in minimizing cross-treatment contamination. These findings establish the 3×3 Latin square design as a practical and bias-controlled framework for research on physics education in whole-class settings.
