Abstract

Limited teaching materials are often a problem in learning in schools. A module is a specific form of teaching material that aims to guide students in understanding a particular material independently. This study aims to determine the feasibility, student responses and effectiveness of the Problem Based Learning (PBL) learning module on chemical bonding material that has been developed. The research method is Research and Development (R&D) using a 4D model that is limited to 3D with stages namely define, design, development due to limited time. Data collection in this study was through interviews, questionnaires and through pre-tests and post-tests. The results showed that the learning module developed had a very good level of validity with percentage scores: 91.66% and 93.75% for the presentation aspect, 95% for the language aspect, 93.75% for the content aspect, 91.66% for the e-module design aspect, and 95% for the material aspect. This electronic-based learning module is declared very valid and suitable for use as teaching material in chemistry learning on chemical bonding material.Keywords: Learning Module, Problem Based Learning, Development, Chemical Bonding, and R&D Method.DOI: 10.23960/jppk.v13.i3.32677

Abstract

Penelitian ini bertujuan untuk mengetahui apakah siswa yang diajar menggunakan model Siklus Pembelajaran 5E yang dibantu Lembar Aktivitas Siswa (LKPD) mencapai hasil belajar yang lebih tinggi dibandingkan siswa yang diajar menggunakan metode ceramah-tanya-jawab dalam materi asam-basa. Penelitian ini juga mengkaji korelasi antara aktivitas belajar dan peningkatan hasil belajar. Pendekatan kuantitatif dengan desain Kuasi-Eksperimental digunakan. Sampel penelitian terdiri dari siswa Kelas XI-4 (eksperimental) dan Kelas XI-5 (kontrol), yang dipilih melalui purposive sampling. Hasil penelitian menunjukkan bahwa siswa yang menggunakan model Siklus Pembelajaran 5E dengan LKPD menunjukkan hasil belajar yang lebih tinggi, dengan thitung ttabel (3,97 1,998) pada tingkat signifikansi 5%, yang mengkonfirmasi Ha. Korelasi yang signifikan ditemukan antara aktivitas belajar dan peningkatan hasil belajar (rhitung rtabel, 0,798 0,362). Dengan nilai korelasi 0,798, aktivitas belajar berkontribusi 62,25% terhadap hasil belajar siswa, sedangkan 37,75% dipengaruhi oleh faktor lain.
