Email this article Enhancing Students’ Activity and Science Concept Mastery using Guided-Inquiry Based Practical Manual
Abstract
This quasi-experimental research aimed to understand the effectiveness of guided-inquiry based practical manual for improving students’ activity and concept mastery of science. Sixty students from SMP Negeri 1 Natar were selected as research samples in this study. This research used two types of data that is quantitative data (pretest, postest, and n-gain) and qualitative data (learning observation and student activity). The results showed that high n-gain score (0.70) for both experimental class 1 and 2. In addition, the assessment of student activity in experimental classes 1 and 2 is also quite good with the score is 86.44% and 85.84%, respectively. Therefore, the use of guided inquiry based practical manuals is highly recommended to improve students’ learning activities and mastery of the science concept.
Keywords: Practical manual, guided inquiry, students’ activity, science concept mastery.
Penelitian kuasi eksperimen ini bertujuan mengetahui keefektifan penggunaan buku petunjuk praktikum berbasis inkuiri terbimbing dalam meningkatkan penguasaan konsep IPA. Sebanyak 60 orang siswa SMP Negeri 1 Natar terpilih secara random sebagai sampel pada penelitian ini. Penelitian ini menggunakan 2 tipe data yaitu data kuantitatif (pretes, postes, dan n-gain) dan data kualitatif (observasi keterlaksanaan pembelajaran dan aktivitas siswa). Hasil penelitian menunjukkan bahwa perolehan n-gain yang cukup tinggi pada kelas eksperimen 1 dan 2 yaitu 0,70. Disamping itu, penilaian aktivitas siswa pada kelas eksperimen 1 dan 2 juga cukup baik dengan perolehan nilai berturut-turut adalah 86,44% dan 85,84%. Oleh karenya, penggunaan buku petunjuk praktikum berbasis inkuiri terbimbing sebagai suplemen belajar siswa sangat dianjurkan untuk dapat meningkatkan aktivitas belajar dan penguasaan konsep IPA.
Kata Kunci: Buku petunjuk praktikum, inkuiri terbimbing, aktivitas siswa, penguasaan konsep sains.
