Abstract
ABSTRAK Penelitian ini bertujuan untuk mendeskripsikan efektivitas model flipped learning berbantuan visualisasi molekul 3D pada materi bentuk molekul untuk meningkat- kan keterampilan mengomunikasikan. Metode penelitian yang digunakan adalah metode kuasi eksperimen dengan pretest-posttest control group design. Populasi dalam penelitian ini adalah seluruh peserta didik kelas XI SMA Negeri 1 Natar. Pengambilan sampel pada penelitian ini menggunakan teknik purposive sampling dan diperoleh kelas XI 1 sebagai kelas eksperimen dan kelas XI 2 sebagai kelas kontrol. Instrumen penelitian yang digunakan yaitu soal pretes dan postes yang terdiri dari 5 butir soal essay serta lembar observasi aktivitas peserta didik di dalam kelas. Data penelitian ini dianalisis menggunakan uji perbedaan dua rata- rata menggunakan Independent sample T-test. Hasil penelitian menunjukkan rata- rata n-Gain keterampilan mengomunikasikan di kelas eksperimen sebesar 0,58 berkategori sedang dan di kelas kontrol 0,27 berkategori rendah, berbeda secara signifikan antara rata-rata n-Gain keterampilan mengomunikasikan di kelas eksperimen lebih tinggi dibandingkan dengan rata-rata n-Gain keterampilan me- ngomunikasikan di kelas kontrol. Hal ini menunjukkan bahwa model flipped learning berbantuan visualisasi molekul 3D pada materi bentuk molekul efektif dalam meningkatkan keterampilan mengomunikasikan peserta didik. Kata kunci : bentuk molekul, flipped learning, keterampilan mengomunikasikan, visualisasi molekul 3D ABSTRACT This study aims to describe the effectiveness of the flipped learning model assis- ted by 3D molecular visualization on molecular shape material to improve com- munication skills. The research method used was a quasi-experimental method with a pretest-posttest control group design. The population in this study were all students of class XI of SMA Negeri 1 Natar. The research sample was taken using a purposive sampling technique, and class XI 1 was obtained as the experimental class and class XI 2 as the control class. The research instruments used were pre- test and posttest questions consisting of 5 essay items and student activity obser- vation sheets in the classroom. The research data were analyzed using a two- mean difference test using an Independent sample T-test. The results showed that the average n-Gain of communication skills in the experimental class was 0.58, categorized as moderate, and in the control class, it was 0.27, categorized as low, with a significant difference between the average n-Gain of communication skills in the experimental class being higher than the average n-Gain of communication skills in the control class. This indicates that the flipped learning model assisted by 3D molecular visualization on molecular shape material is effective in impro- ving students' communication skills. Keywords: communication skills, 3D molecular visualization, molecular shape, flipped learning
