Abstract

Physics instruction at a private high school in Medan still focuses on lectures, which results in students being less active in class and their critical thinking skills needing improvement. Additionally, instructional models and media that engage students in problem-solving have not been successful. The conditions of physics instruction, students’ critical thinking skills, and the need to implement a problem-based learning (PBL) model supported by worksheets in physics instruction are the objectives of this study. This study was conducted using a qualitative descriptive method and a preliminary survey (pre-study). The research subjects consisted of 25 eleventh-grade students and one physics teacher. Data were collected through interviews and questionnaires. Qualitative descriptive analysis was performed on the interview data, and percentage analysis was performed on the questionnaire data. The results of the study indicate that students require more active and engaging learning that involves direct problem-solving; their interest in the use of learning media increased by 85% and fell into the high category, the problem-based learning model increased by 82% and fell into the high category, and their critical thinking skills increased by 78% and fell into the fairly high category. This study found that the implementation of a problem-based learning model supported by worksheets can help improve students’ learning activities and critical thinking skills in physics learning.

Abstract

In physics education, conceptual understanding is crucial because it helps students grasp the relationships between concepts, formulas, and natural phenomena as a whole. Complex physics concepts and a lack of variety in teaching materials often make it difficult for students to grasp the material. The purpose of this study is to examine how teachers use teaching materials to influence students’ understanding of physics at a private high school in Medan. The study employs a qualitative descriptive approach supported by simple quantitative data. The research subjects consisted of 25 students and one physics teacher. Data were collected through classroom observations, interviews with the teacher, and a questionnaire distributed to students. Observation and interview data were analyzed qualitatively through reduction, presentation, and drawing of conclusions, while questionnaire data were analyzed using percentages. The results of the study indicate that the use of instructional media in physics instruction is not yet ideal because lecture-based methods are still dominated by PowerPoint and the blackboard. Questionnaire results show that 96 percent of students have difficulty understanding abstract physics concepts, 92 percent have difficulty connecting concepts to daily life, and 100 percent of students say that instructional media make learning easier. Interview results indicate that simulations, laboratory experiments, and educational videos can enhance students’ understanding of concepts and their interest in learning. Limited class time and school facilities are the main constraints. This study found that improvements in students’ understanding of physics concepts are significantly influenced by the use of various types of instructional media.

Abstract

Proses pembelajaran di sekolah masih sering berpusat pada guru sehingga kurang memberikan kesempatankepada peserta didik untuk melakukan penyelidikan, analisis dan pemecahan masalah secara mandiri. Kondisi tersebutmenuntut penerapan model pembelajaran yang mampu melibatkan peserta didik secara aktif dalam prosespembelajaran. Penelitian ini bertujuan untuk menganalisis peran model Modified Free Inquiry (MFI) dalam meningkatkan keterampilan berpikir kritis peserta didik melalui kajian literatur. Metode yang digunakan adalah studi kepustakaan dengan menelaah 20 artikel ilmiah dari jurnal nasional dan internasional yang relevan. Hasil kajian menunjukkan bahwa penerapan model MFI efektif dalam meningkatkan keterampilan berpikir kritis, analitis, dan divergen siswa pada berbagai mata pelajaran seperti fisika, biologi, dan IPA. Model ini mendorong proses berpikir aktif melalui kegiatan refleksi dan diskusi terbimbing, sehingga peserta didik mampu menganalisis data, menarik kesimpulan, dan menyusun strategi logis. Selain itu, MFI juga berdampak positif terhadap keterampilan proses sains, kemampuankolaborasi, dan literasi digital, serta mampu mengurangi miskonsepsi dalam pembelajaran. Model ini juga fleksibeluntuk diintegrasikan dengan teknologi pembelajaran daring. Namun, efektivitasnya cenderung lebih optimal pada peserta didik dengan kemampuan awal tinggi, sehingga diperlukan strategi pendukung untuk mengakomodasi perbedaan kemampuan. Dengan demikian, MFI memiliki potensi sebagai alternatif model pembelajaran abad ke-21 yang berorientasi pada pengembangan keterampilan berpikir tingkat tinggi.
