Abstract

Science education is a key factor in developing students' science process skills and understanding of scientific concepts. Mastery of science process skills is one of the important ways to gain knowledge. By implementing Student Worksheets based on guided inquiry, science process skills and understanding of scientific concepts can be improved. This study examines the effect of guided inquiry-based worksheets on science process skills. This study used a quasi-experimental design with a one-group pretest-posttest model to examine the effectiveness of guided inquiry-based worksheets in improving students' science process skills on vibration and wave material. The research participants consisted of students enrolled in vibration and wave courses in the third semester of the Physics Education Study Program, Universitas PGRI Pontianak, who were selected using saturated sampling techniques. The instruments used in this study were science process skills tests in the form of pretests and posttests and science process skills observation sheets during learning which included observing, classifying, measuring, interpreting data, making hypotheses, designing experiments, conducting experiments, communicating, results, concluding, identifying variables, and using tools and materials. The data obtained were analyzed using paired t-test and N-Gain analysis. Based on the data obtained, both from pretest, posttest, and observation, it can be concluded that the use of guided inquiry-based worksheets is effective in improving students' science process skills in vibration and wave material. This increase is clearly seen in the pretest and posttest scores, as well as in the observation of skills that show positive developments in all indicators of science process skills.

Abstract

Pemahaman siswa terhadap konsep fluida dinamis masih rendah karena terbatasnya media visual interaktif yang dapat digunakan secara mandiri. Hal ini menghambat proses pembelajaran fisika yang menuntut kemampuan visualisasi dan eksplorasi konsep-konsep yang kompleks. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis Construct 3 pada materi fluida dinamis dengan menggunakan model pengembangan 4D yang dibatasi pada tahap Define dan Design. Metode yang digunakan adalah research and development (R&D) dengan pendekatan kualitatif deskriptif. Tahap Define meliputi analisis kurikulum, karakteristik peserta didik, dan materi pembelajaran, sedangkan tahap Design mencakup perancangan flowchart media, tampilan awal, aset visual, dan spesifikasi teknis awal media. Hasil penelitian menunjukkan bahwa desain media telah selesai sekitar 85%, mencakup seluruh flowchart interaksi, tampilan antarmuka utama, aset grafis dan audio, serta rancangan navigasi dan animasi dasar. pada tahap ini belum dilakukan uji kevalidan maupun kepraktisan, sehingga belum tersedia indikator keberhasilan secara kuantitatif. Kedepannya proses validasi akan melibatkan validator ahli materi dan ahli media dengan kriteria penilaian seperti kesesuaian konten dengan kurikulum, kejelasan penyampaian konsep, kualitas tampilan visual, navigasi, interaktivitas, serta kemudahan penggunaan oleh siswa. Media yang dikembangkan memiliki potensi besar dalam mendukung pembelajaran mandiri dan visualisasi konsep fisika yang kompleks. Media yang dikembangkan memiliki potensi besar dalam mendukung pembelajaran mandiri dan visualisasi konsep fisika yang kompleks. Selain itu, media ini sejalan dengan prinsip Kurikulum Merdeka karena memungkinkan diferensiasi pembelajaran dan mendorong kemandirian siswa. Implikasi praktis dari penelitian ini adalah memberikan dasar rancangan awal yang dapat digunakan sebagai pijakan untuk tahap pengembangan dan pengujian lebih lanjut, guna memperoleh media yang valid, praktis, dan efektif untuk digunakan dalam pembelajaran fisika di sekolah. Penelitian ini memberikan dasar yang kuat untuk pengembangan tahap selanjutnya agar media dapat diterapkan secara luas dalam pembelajaran fisika di sekolah.

Abstract

Physics teachers need to pay more attention to each student's unique way of thinking, strive to recognize and correct misunderstandings, and apply cognitive learning methods such as assimilation and accommodation. The use of cognitive dissonance can be used as a tool to change students' way of thinking. Additionally, it is important to simplify experiments and provide practical exercises that can deepen students' understanding. Teachers must also be able to relate lesson material to real life and understand the role of emotions in the teaching and learning process. Therefore, it is necessary to have teacher self-confidence through self-efficacy. This study aims to provide a comprehensive understanding of the condition of educators' self-efficacy in West Kalimantan and its impact on learning. This research is a descriptive research. The population of this research is all physics teachers in West Kalimantan. The sample was selected using probability sampling technique. The number of samples in this study were 100 physics teachers from 13 cities/districts in West Kalimantan. Data collection technique is indirect communication. Data analysis used descriptive statistics, followed by a description of the physics teacher's level of self-efficacy. Based on the research results it was concluded that the average self-efficacy level of physics teachers in West Kalimantan was quite high. The factors measured, namely the efficacy in learning strategies, classroom management, and student involvement all show a good level of self-efficacy. Physics teachers in West Kalimantan demonstrated high efficacy in developing learning strategies and managing classrooms, and had sufficient confidence in engaging students in the learning process.

Abstract

Based on pre-observation results, researchers found that student learning outcomes in electromagnetic induction material were still below the standards set by the school. This is due to the lack of learning media used. Therefore, it is necessary to develop innovative media that can support learning, namely blog-based learning media. This research aims to determine feasibility according to media experts, feasibility according to material experts, and test students' responses to the media being developed. This research uses Thiagarajan's R&D steps with a 4D model, namely (Define, Design, Develop, and Disseminate), but in its implementation in this research it is modified to 3D, namely Define, Design, and Develop. The results of data analysis show that from the media aspect it is categorized as very appropriate with a score of 91%, from the material aspect it is categorized as appropriate with a score of 75% and the results of student responses to the media being developed are categorized as very feasible with a score of 95%. Based on this, it can be concluded that the learning media with the Academic Blog is said to be suitable for use in learning electromagnetic induction material.
