Abstract


Penelitian ini bertujuan untuk mengetahui pengaruh penerapan hypothetico-deductive reasoning (HDR) dalam learning cycle terhadap keterampilan proses sains (KPS) dan pemahaman konsep siswa. Penelitian ini berbentuk kuasi-eksperimen dengan desain pretest-postest non-equivalent control group yaitu kelas A sebagai kelompok eksperimen bermodelkan HDR-Learning Cycle (HDR-LC), serta kelompok kontrol yaitu kelas B bermodelkan Learning Cycle (LC) dan kelas C bermodelkan Direct Instruction (DI). Sumber data KPS-intelektual dan pemahaman konsep diperoleh dengan instrumen tes sedangkan KPS-manual diperoleh dengan observasi performansi. Data dianalisis dengan MANOVA dilanjutkan uji Bonferroni, atau uji Kruskal-Wallis dilanjutkan uji Games-Howell untuk data nonparametrik. Hasil penelitian ini yaitu: (a) penerapan HDR-LC (mean: 86,4) secara signifikan berpengaruh positif terhadap KPS-intelektual dibandingkan model LC (mean: 78,3) dan DI (mean: 75,1). Sedangkan KPS-manual kelas HDR-LC (mean: 64,3) dibandingkan kelas LC (mean: 87,4) dan DI (mean: 82,3) terdapat perbedaan yang signifikan dengan pengaruh negatif. (b) penerapan HDR-LC (mean: 84,8) secara signifikan berpengaruh potisif terhadap pemahaman konsep siswadibandingkan model LC (mean: 61,7) dan DI (mean: 66,6).
