Abstract

Force is one of the most fundamental concepts in physics, used to describe and explain a wide range of phenomena. Students can use force diagrams to learn about fundamental force concepts and solve problems related to forces. However, a limited study has focused on students’ views in drawing force diagrams. This study aims to explore students’ views about force diagrams while solving physics problems. A qualitative study was conducted to explore students’ views on drawing and using force diagrams when solving force problems, involving 18 physics education students. Before the semi-structured interviews were conducted, the students were given two force problems to solve. All interviews were recorded, transcribed, and coded for analysis. Data from the interview was analyzed using NVivo software. This study identified five themes related to students’ views on force diagrams: purposes, conventions, physics concepts, mathematical concepts, and incomplete diagrams. The most frequently mentioned theme by students was the purpose of drawing force diagrams. Students’ knowledge about force concepts and trigonometry also affected their diagrams. Students had different ways to draw diagrams, either on the dot or on the object, and had reasons for drawing the incomplete force diagrams. These findings suggest that students should possess sufficient knowledge of physics and mathematics to draw force diagrams effectively. Students should also understand when force diagrams are applicable and recognize the advantages of drawing them. This study suggests that to support students' effective understanding of force diagrams, educators should employ appropriate strategies and equip students with the skills to create and utilize force diagrams while learning about force concepts and solving problems.

Abstract

This research aims to produce the Testlets' model instrument test that measures the problem-solving abilities of high school students in West Kalimantan on motion topics. The study employed A.D.D.I.E.'s development model, which consists of analysis, design, development, implementation, and evaluation stages. Three hundred four students from three different cities in West Kalimantan were involved as respondents in this study. The researchers collected data through test techniques and documentation since this study focused on the characteristics of the test. The instrument test of problem-solving abilities is designed to follow Heller's solution stages, namely focusing on the problem, describing physics, planning a solution, implementing the plan, and evaluating the answer. The results of this study are the availability of 20 multiple-choice questions, with five main questions and four testlets. The assessment instrument developed had the characteristics of validity up to 0.90 (high), reliability through Cronbach's Alpha Reliability analysis: 0.83 (very good), person reliability: 0,84 (high) and item reliability: 0.98 (excellent). The test developed is theoretically and practically feasible so that high school physics teachers can use it to measure students' problem-solving abilities more quickly because it uses a multiple-choice test.

Abstract

Terdapat faktor menentukan kesuksesan hasil belajar satu diantaranya keaktifan belajar peserta didik.Tujuan penelitian mengetahui bagaimana keantifan belajar dan hasil belajar serta korelasi antara keaktifan dan hasil belajar peserta didik. subjek penelitian yaitu 38 orang kelas XII MIPA SMA Negeri 4 Pontianak. metode penelitian kuantitatif dengan teknik penelitian studi kasus melalui observasi dengan angket keatifivitas dan data hasil asessment formatif peserta didik. analisis data dengan SPSS. Keaktifan belajar peserta didik di kelas XII MIPA 1 SMA Negeri 4 Pontianak menunjukkan tingkat yang cukup dengan persentase sebesar 67,76%. Sementara itu, hasil belajar peserta didik mencapai rata-rata 86,60, yang dapat dikategorikan sebagai tinggi. Analisis statistik menggunakan SPSS mengungkapkan adanya korelasi signifikan antara keaktifan dan hasil belajar peserta didik,  nilai r adalah 0,000 yang lebih kecil dari 0,05. Korelasi ini sangat kuat, mencapai koefisien 0,874, menunjukkan hubungan positif: ketika keaktifan belajar tinggi, hasil belajar peserta didik juga tinggi, dan sebaliknya.

Abstract

This study aims to determine the improvement in students' learning outcomes on Newton's Laws material at SMA Kemala Bhayangkari 1 Kubu Raya, through differentiated learning using the discovery learning model. The research design employed is a quasi-experimental design with a nonequivalent control group design. The research sample consisted of Class XI Physics 1 and Class XI Physics 2, each with 31 students, selected using the intact group random sampling technique. The instrument used was a test. The data were analyzed using descriptive and inferential statistical analysis techniques. In the pretest, the experimental class obtained a score of 25.16, and the control class 15.48, both falling  in the low category. After the treatment, the experimental class's posttest score increased to 84.83 (high category), while the control class reached 50 (medium category). Based on Cohen’s d effect size value, the effectiveness of implementing differentiated learning with the discovery learning model in improving learning outcomes was 2.042, which falls into the high category. In addition, based on a learning style questionnaire, 20 students preferred the auditory learning style. This study concludes that the implementation of differentiated learning using the discovery learning model is effective in improving students' learning outcomes on Newton’s Laws material.

Pelaksanaan penelitian dilakukan di SMP Panca Setya 2 Sintang pada mata pelajaran PAK. Subjek penelitian pada penelitian ini terdiri dari 2 orang validator ahli materi, 2 orang validator ahli media, 31 peserta didik uji empiris, dan 44 peserta didik kelas eksperimen serta kelas kontrol. Hasil respon peserta didik terhadap e-modul menggunakan skala likert 1-4. Ada empat aspek dalam angket respon yakni tampilan memperoleh skor 64%, kebahasan 72%, kemanfaatan 72%, dan pembelajaran 68% yang menyatakan bahwa e-modul sesuai kebutuhan belajar peserta didik. Berdasarkan hasil belajar diperoleh nilai effect size sebesar 1,05 yang dapat diinterpretasi bahwa memiliki efek kuat. Oleh karena itu, dapat disimpulkan bahwa e-modul berbasis PBM dinyatakan efektif bagi pembelajaran agama Katolik di kelas 7
