Abstract

Penggunaan alat peraga di sekolah dapat membantu guru dalam menjelaskan konsep fisika. Namun, masih sering ditemukan alat peraga yang belum digunakan secara optimal yang berdampak pada kesulitan siswa dalam memahami materi yang diajarkan. Penelitian ini bertujuan untuk mengidentifikasi keberhasilan dalam pembelajaran fisika menggunakan alat peraga venturimeter pada materi fluida dinamis pada siswa kelas XI MIPA. Penelitian ini menggunakan metode kualitatif dengan skema naratif deskriptif. Informan dalam penelitian ini melibatkan 36 siswa kelas XI MIPA. Metode yang digunakan dalam mengumpulkan data yaitu dokumentasi, wawancara, observasi, dan data kepustakaan. Pengambilan sampel menggunakan teknik purposive sampling dan snowball. Penelitian ini dianalisis dengan model analisis interaktif dari Miles dan Haberman yang meliputi pengumpulan data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan hasil yang baik yaitu lebih dari setengah siswa mampu mencapai nilai di atas KKM sekolah. Siswa mengalami peningkatan setelah menggunakan alat peraga venturimeter. ketertarikan siswa pada alat peraga venturimeter terlihat dari antusiasme yang lebih tinggi saat alat peraga ini digunakan dalam pembelajaran. Ketertarikan terhadap alat peraga pada pembelajaran tersebut berdampak positif pada aktivitas pembelajaran yang ditunjukkan saat pengamatan dan evaluasi siswa yang mengalami peningkatan. Implikasi penelitian ini ialah, penggunaan alat peraga venturimeter dapat meningkatkan pemahaman siswa terhadap konsep fluida dinamis secara signifikan. Dengan alat peraga ini, siswa dapat melihat secara langsung fenomena perubahan tekanan dan kecepatan aliran fluida, yang abstrak menjadi lebih konkret.

Abstract

This article provides an overview and explanation of a product in virtual laboratory media based on the development of discovery learning with a focus on the material of the photoelectric effect. The paper also outlines the readability and practicality aspects for both students and teachers in the virtual lab while explaining the effectiveness of the virtual lab in enhancing students' critical thinking skills. The product discussed in this article was developed using the 4D model and scheme. It has undergone expert validation and product testing. The research presented in this article was conducted at two public high schools in Yogyakarta. The study utilized questionnaires, observation sheets, expert validation sheets, readability sheets, practicality sheets, and tests. The research data was analyzed using Gregory's analysis for expert validation and Manova's analysis for field testing. The study results indicate that the virtual lab is deemed appropriate as a learning medium based on expert validation for the photoelectric effect material. From the perspectives of readability and practicality, the developed product falls into the excellent category. This study, using the Manova test, effectively illustrated a substantial enhancement in the critical thinking abilities of students, notably in the areas of analysis, elaborating on concepts, and forming conclusions. Consequently, this paper offers a detailed insight into the creation of novel educational tools and presents robust empirical data supporting their role in improving critical thinking in students, with a specific focus on the subject of the photoelectric effect.

Abstract

This research aims to evaluate the effectiveness of using discovery-based virtual laboratories in enhancing students' scientific attitudes towards the topic of the photoelectric effect. The method employed a quasi-experimental design involving 12th-grade students at SMAN 2 Yogyakarta. The research design employed is pretest-posttest, nonequivalent multiple-group design. Subject selection was conducted through purposive sampling, resulting in experimental and control classes. The research subjects were from classes 12 MIPA 4 and 12 MIPA 5. Data were collected through questionnaires and observations of scientific attitudes. Observations during the learning process were conducted by three observers. The results of the study showed an improvement in the understanding of physics concepts and the development of scientific attitudes in the experimental group, with an average score of 89.36. The improvement in the experimental group was higher than that in the control group. These findings indicate that virtual laboratories based on discovery learning are effective in enhancing students' scientific attitudes. This finding highlights the potential of virtual laboratories in fostering scientific attitudes and assisting students in understanding modern physics, thereby stimulating their interest in the subject. The positive implications for physics education indicate that this approach can address students' challenges in learning physics conventionally

Abstract

This community service activity aimed to improve teachers' competency in analyzing learning evaluation instruments through training on Quest software based on the Rasch Model. The participants were 25 high school teachers in Tondano, conducted online via Zoom over two days using a participatory training approach. The method included preparation, execution (conceptual reinforcement, demonstration, hands-on practice, and reflective discussion), and evaluation stages. Data were collected through pretests-posttests, questionnaires, and observations, then analyzed descriptively. Results showed a significant increase in competency, with the average pretest score of 46.80 increasing to 81.20 on the posttest (a 73.50% increase). The N-Gain value of 0.65 falls into the medium category, indicating meaningful training effectiveness. A total of 92% of participants showed substantial improvement and were able to operate Quest and interpret outputs such as item difficulty (logit), item fit statistics (INFIT/OUTFIT MNSQ), and reliability. Participant responses were very positive, with 88% stating the material was relevant and 84% committing to apply the training results in their schools. This activity contributes to strengthening teachers' pedagogical competence in evidence-based learning evaluation.
