PENGARUH MODEL DISCOVERY LEARNING TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN HASIL BELAJAR SISWA

Abstract

The purpose of this research was to determined the influence of discovery learning model to critical thinking and students' learning outcomes on ecosystem subject matter. The design of this research was control group pretest postest. The qualitative data were obtained through answers of students worksheet and students' perception which analyzed by descriptive. The quantitative data were obtained from pretest and postest which analyzed with t test and signification level of 1%. The result showed that average of percentage critical thinking skills on experiment class was higher than control class (experiment = 75,58%, good characterized; control = 70,08%, sufficient characterized). Students' learning outcomes on experiment class also infulenced significantly with average score of N-Gain (experiment = 65,06; control = 47,13). Besides that, all of students gave a positive responses to the discovery learning model. It could be concluded discovery learning model influenced to increasing critical thinking skills and students' learning outcomes on ecosystem subject matter.

Penelitian ini bertujuan untuk mengetahui pengaruh model discovery learning terhadap kemampuan berpikir kritis dan hasil belajar siswa pada materi pokok ekosistem. Desain penelitian Control Group Pretest-Postest. Data penelitian data kualitatif diperoleh dari jawaban LKS dan persepsi siswa yang dianalisis secara deskriptif. Data kuantitatif diperoleh dari nilai pretest dan postest yang dianalisis menggunakan Uji t dengan taraf signifikasi 1%. Hasil penelitian menunjukkan rata-rata persentase kemampuan berpikir kritis siswa kelas eksperimen lebih tinggi dari kelas kontrol (eksperimen = 75,58% dengan kriteria baik; kontrol = 70,08% dengan kriteria cukup). Hasil belajar siswa kelas eksperimen juga berpengaruh sangat signifikan dengan nilai rata-rata N-gain (eksperimen = 65,06; kontrol = 47,13). Kemudian, semua siswa memberikan tanggapan positif terhadap model discovery learning. Dengan demikian, dapat disimpulkan bahwa model discovery learning sangat berpengaruh dalam meningkatkan kemampuan berpikir kritis dan hasil belajar siswa pada materi pokok ekosistem.
