Abstract

Observasi dilakukan melalui wawancara dengan guru fisika di SMA Negeri 1 Wundulako bahwa beberapa siswa masih belum terbiasa dengan soal pemecahan masalah, sehingga mengakibatkan kesulitan dalam menganalisis masalah yang disajikan oleh guru. Penelitian ini bertujuan untuk menilai sejauh mana keterampilan pemecahan masalah fisika siswa melalui penerapan model PBL dengan pendekatan kontekstual, mengevaluasi efektivitas PBL dalam meningkatkan keterampilan ini, dan memeriksa hubungan dua arah antara kedua variabel. Penelitian ini merupakan penelitian eksperimental dengan menggunakan desain pra-eksperimental. Kami memberikan pretest dan posttest kepada subjek untuk mengumpulkan data. Temuan pretest penelitian menghasilkan skor rata-rata 57,096, sedangkan hasil posttest menunjukkan rata-rata 77,096, yang mengarah pada kesimpulan bahwa penerapan PBL menggunakan pendekatan kontekstual secara efektif meningkatkan keterampilan pemecahan masalah fisika. Akhirnya, melalui pengujian hipotesis dengan menggunakan metode uji-t, nilai-p ditemukan kurang dari 0,05, yang menunjukkan signifikansi statistik; Oleh karena itu, kami menolak hipotesis nol H0 dan menerima hipotesis alternatif H1 yang menyatakan pentingnya penerapan model pembelajaran ini dalam konteks kelas untuk mengajarkan kurikulum Gelombang Berjalan dan Gelombang Stasioner.

Abstract

The urgency of this research is driven by a range of issues encountered in the implementation of the Merdeka Curriculum, particularly concerning the development of valid, practical, effective, and efficient learning media based on E-Learning to facilitate the digitalization of schools. This is particularly relevant in the context of physics education, which demands a meticulous approach to deliver immersive learning experiences grounded in real-world phenomena. The primary objective of this study is to develop E-Learning physics using Google Sites assisted by Quizizz and PhET Simulations, that are valid, practical, and effective to enhance students' interest and engagement in learning physics. These efforts are particularly significant in the context of implementing the Merdeka Curriculum in Senior High Schools. The research methodology is Research and Development (R&D) through modification on steps of 4D Models into 3D Models (Define, Design, and Develop) with an additional quantitative descriptive analysis to gauge the extent of teacher competence in utilizing the developed products. The results show that E-Learning using Google Sites assisted by Quizizz and PhET Simulations have been validated using Gregory index, namely 0.69 for the internal consistency coefficient on the material and 0.76 for the internal consistency coefficient on the media, and proven to be effective in boosting student engagement and interest namely 82% approval rating for the media developed in the realm of physics learning , particularly within the framework of the Merdeka Curriculum.
