Abstract

Penelitian ini bertujuan mengetahui pengaruh penerapan Conceptual Change Model terhadap pemahaman konseptual siswa pada materi stoikiometri. Penelitian dilaksanakan di SMAN 50 Jakarta pada semester genap tahun pelajaran 2023/2024. Penelitian ini menggunakan metode quasi experimental melalui pretest–posttest nonequivalent group design. Teknik pemilihan sampel menggunakan purposive sampling dengan kelas X-3 sebagai kelas eksperimen yang menerapkan Conceptual Change Model dan kelas X-6 sebagai kelas kontrol yang menerapkan Generative Learning Model. Sampel penelitian ini berjumlah 72 siswa. Instrumen yang digunakan adalah tes pilihan ganda dua tingkat sebanyak 20 butir. Hasil penelitian menunjukkan bahwa rata-rata skor posttest kelas eksperimen (89,097) lebih tinggi dibandingkan kelas kontrol (81,111). Nilai N�Gain kelas eksperimen lebih tinggi (0,80) dibandingkan kelas kontrol (0,65).Persentase ketuntasan belajar siswa kelas eksperimen sebesar 97,2% dan kelas kontrol sebesar 72,2%. Hasil uji U Mann Whitney, data gain score pada kedua kelas memperoleh p value (Sig. 1-tailed) lebih kecil dari 0,05. Sehingga median data skor pemahaman konseptual kelompok siswa yang diberikan perlakuan CCM lebih tinggi dibandingkan kelompok siswa yang diberikan perlakuan GLM. Nilai effect size kelas eksperimen sebesar 7,027 dan kelas kontrol sebesar 4,190. Oleh karena itu, dapat disimpulkan bahwa penerapan conceptual change model berpengaruh signifikan terhadap pemahaman konseptual siswa pada materi stoikiometri.*****This research aims to determine the effect of implementing the Conceptual Change Model on students' conceptual understanding of stoichiometry. The research was conducted at SMAN 50 Jakarta in the even semester of the 2023/2024 academic year. This research uses a quasi-experimental method through a pretest–posttest nonequivalent group design. The technique sampling uses purposive sampling with class X-3 as the experiment class that applied the Conceptual Change Model and class X-6 as the control class that applied the Generative Learning Model. The research sample consisted of 72 students. The instrument used was two tiers multiple choice test with 20 items. The results showed that the posttest average for the experiment class (89.097) was higher than the control class (81.11). The N-Gain score for the experiment class (0.80) was higher than the control class (0.65). The percentage of learning completeness for experiment class students is 97.2% and control class is 72.2%. Based on the Mann Whitney U test, the gain score data in both classes obtained p value (sig. 1 tailed) smaller than 0,05. So the median conceptual understanding score data for the group of students given CCM treatment is higher than the group of students given GLM treatment. The effect size value for the experimental class is 7.027 and the control class is 4.190. Based on the result this study, it can be concluded that application of the conceptual change model has a significant effect to student’s understanding in Stoichiometry topic.
