摘要：Tujuan dari penelitian ini adalah untuk menentukan apakah kemampuan pemahaman konsep siswa yang diajar dengan model Concept Attainment lebih baik daripada siswa yang diajar dengan model Ekspositori,apakah kemampuan pemahaman konsep siswa yang diajar dengan menggunakan model Cognitive Growth lebih baik daripada siswa yang diajar dengan menggunakan model Ekspositori,dan apakah kemampuan pemahaman konsep siswa yang diajar dengan menggunakan model Concept Attainment lebih baik daripada siswa yang diajar dengan model Cognitive Growth. Sampel dalam penelitian ini dipilih secara acak,didapatkan dua kelas eksperimen dan satu kelas kontrol. Metode yang digunakan adalah metode dokumentasi dan metode tes. Analisis data yang digunakan meliputi uji normalitas,uji homogenitas,uji ketuntasan belajar individual,uji ketuntasan belajar klasikal,uji anava,dan uji LSD. Hasil penelitian menunjukkan bahwa kemampuan pemahaman konsep siswa yang diajar dengan model pembelajaran Concept Attainment tidak berbeda secara signifikan dengan siswa yang diajar dengan menggunakan model pembelajaran Cognitive Growth,namun kemampuan pemahaman konsep siswa yang diajar dengan model pembelajaran Concept Attainment maupun Cognitive Growth lebih baik daripada siswa yang diajar dengan model pembelajaran ekspositori.
其他摘要：The object of this research was to determined whether students' concept understanding who were taught by Concept Attainment model was better than students who were taught by Expository model,wheter students' concept understanding who were taught by Cognitive Growth model was better than students who were taught by Expository model,and wheter students' concept understanding who were taught by Concept Attainment model was better than students who were taught by Cognitive Growth model. Sampels in this research were chosen randomly,chosen 2 experiment class and one control class. The used methods were documentation method and test method. Data analisyses were normality test,homogenity test,individual completeness test,clasical completeness test,anava tes,and LSD test. The result showed that students’ concept understanding in class which used concept attainment model and class which used cognitive growth model was better than students in class which used expository model. But there was not significant difference students’ concept understanding between student in class which used concept attainment model and student in class which used cognitive growth model.
