Yunita, Hendro Pranoto — Wed, 30 Sep 2026 00:00:00 +0000

The purpose of this study is to examine the effect of the PjBL model on students’ learning outcomes in the topic of environmental pollution.
The method used is quasi-experimental with a Two Group Pretest-Posttest design. The population includes all Grade X students at SMAN 1 Selesai, consisting of 9 classes. The sample was selected using a purposive sampling technique. Data collection to measure cognitive ability was carried out using multiple-choice questions, consisting of 25 pretest and posttest items. The results of the normality and homogeneity tests using the Kolmogorov-Smirnov method showed a significance value (Sig.) > 0.005. The research findings were analyzed using a t-test, which yielded a significance value (Sig.) of 0.000 < 0.05.

Pendidikan memiliki peran penting dalam meningkatkan kualitas sumber daya manusia untuk mendukung pembangunan bangsa. Namun, sistem pendidikan di Indonesia masih menghadapi berbagai tantangan, termasuk rendahnya kemampuan siswa dalam memecahkan masalah. Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran kolaboratif diferensiasi berbasis Technological Pedagogical Content Knowledge (TPACK) terhadap motivasi dan kemampuan pemecahan masalah siswa SMA pada materi gelombang dalam mendukung implementasi Kurikulum Merdeka. Penelitian dilaksanakan di SMA Negeri 1 Merbau dengan desain eksperimen semu yang melibatkan dua kelas, yaitu kelas eksperimen dengan model pembelajaran kolaboratif diferensiasi berbasis TPACK dan kelas kontrol dengan pembelajaran konvensional. Data dikumpulkan melalui pretest, posttest, angket, dan wawancara, kemudian dianalisis menggunakan uji statistik, termasuk MANOVA dan uji effect size. Hasil penelitian menunjukkan bahwa rata-rata motivasi dan kemampuan pemecahan masalah siswa pada kelas eksperimen lebih tinggi (70,57) dibandingkan kelas kontrol (62,48). Analisis data mengungkapkan adanya pengaruh signifikan penggunaan model pembelajaran kolaboratif diferensiasi berbasis TPACK terhadap peningkatan motivasi dan kemampuan pemecahan masalah siswa. Dengan demikian, model pembelajaran ini terbukti efektif dalam menciptakan suasana belajar interaktif, partisipatif, dan relevan dengan kebutuhan pendidikan abad ke-21.

Analisis Kesulitan Belajar Siswa Pada Materi Sistem Peredaran Darah Di MAS Insan Kesuma Madani T.P 2024/2025

This study aims to determine the percentage of completion and factors that cause learning difficulties of class XI MAS Insan Kesuma Madani students on the material of the circulatory system. The type of research is quantitative descriptive. The research sample was taken using a saturated sampling technique or census, namely the population is the sample. Data collection techniques used tests and questionnaires. The results of the study showed that learning completion was 11%, and learning difficulties occurred in 89% of class XI MAS Insan Kesuma Madani students. The factors causing students' learning difficulties from the highest to the lowest in sequence are the nature of the material, facilities & learning time, student attitudes & interests, teacher teaching styles and student learning habits. Therefore, it is necessary to adjust teaching methods, fulfill the required teaching materials, optimize facilities and learning time, increase student motivation and interest so that the nature of the material that makes it difficult for students can be more easily understood..

Analisis Pemahaman Konsep Dinamika Gerak Statis Pada Siswa Kelas XI Di SMA Swasta St Maria Kabanjahe dan SMA Swasta St Ignasius Medan

Michael Yosua Ginting — Wed, 30 Sep 2026 00:00:00 +0000

The aim of this research is to compare the understanding of students in SMA Swasta Ignasius Medan and SMA Santa Maria Kabanjahe regarding the topic of dynamics in physics. Students' understanding of the concepts in dynamics is an important aspect in comprehending the basic principles of physics.

The research method used is a survey using a questionnaire distributed to students in both schools. The questionnaire is designed to measure students' understanding of key concepts in dynamics, such as Newton's laws, force, acceleration, and momentum. The collected data is then analyzed statistically to compare the level of understanding of students in both schools.The results of this research are expected to provide a better understanding of the difference in the level of understanding of students in SMA Swasta Ignasius Medan and SMA Santa Maria Kabanjahe regarding the topic of dynamics in physics. Additionally, this research can provide input for both schools to improve students' understanding in the subject of physics, particularly in dynamics.

The conclusion of this research will provide an overview of the difference in students' understanding of the topic of dynamics in both schools. The results of this research can be used as a basis for developing more effective teaching strategies in understanding the concepts in dynamics in both schools

Analisis Kemampuan Pemahaman Konsep Siswa SMA Kelas XI Terhadap Pelajaran Fisika Pada Materi Fluida Dinamis

Putri Rahayu — Wed, 30 Sep 2026 00:00:00 +0000

The aim of this study is to analyze students' understanding of physics learning concepts, particularly in the area of dynamic fluid materials. The research method employed is descriptive research with a quantitative approach. The research subjects are 20 students, 10 from MAN 2 MODEL MEDAN, and 10 from SMA Swasta Kesuma Bangsa Londut, all in grade XI. The results of this study indicate that students' comprehension of dynamic fluid concepts can be categorized as moderate. However, there are still some questions where students' understanding falls into the low category. Therefore, there is a need for a learning design that can engage students in physics education, enabling them to comprehend and explore physics concepts comprehensively.
