PENGARUH PENGGUNAAN LKS BERBASIS INKUIRI TERBIMBING TERHADAP KETERAMPILAN PROSES SAINS SISWA

This study aimed to determine the effect of Student Work Sheet based on Guided Inquiry of students Science Process Skill. Study design was pretest-posttest non-equivalent group. Samples were VII3 and VII4 SMPN 1 Pagelaran which were chosen by Purposive Sampling. Quantitative data which obtained from the average value of test were analyzed by t-test and U-test. The qualitative data was observation of Science Process Skill and questionnaire responses that analyzed descriptively. The results showed that the average value of N-gain (69,99) in experiment class was higher than control class (46,69), significantly. Observation result of Science Process Skill has high criteria (79,16%), and most of the students gave positive respond to Student Work Sheet based on Guided Inquiry. Therefore, using Student Work Sheet based on Guided Inquiry could increase Science Process Skill.Penelitian ini bertujuan mengetahui pengaruh penggunaan Lembar Kerja Siswa (LKS) berbasis Inkuiri Terbimbing terhadap Keterampilan Proses Sains (KPS) siswa. Desain penelitian pretes-postes kelompok tak ekuivalen. Sampel penelitian kelas VII3 dan VII4 SMPN 1 Pagelaran, dipilih secara Purposive Sampling. Data kuantitatif diperoleh dari nilai rata-rata tes yang dianalisis menggunakan uji-t dan uji-U. Data kualitatif berupa data observasi KPS dan angket tanggapan siswa yang dianalisis secara deskriptif. Hasil penelitian menunjukkan rata-rata N-gain kelas eksperimen lebih tinggi (69,99) berbeda signifikan dengan kelas kontrol (49,69). Hasil rata-rata persentase observasi KPS memiliki kriteria tinggi (79,16%) dan sebagian besar siswa memberikan tanggapan positif terhadap penggunaan LKS berbasis Inkuiri Terbimbing. Dengan demikian penggunaan LKS berbasis inkuiri terbimbing dapat meningkatkan keterampilan proses sains.Kata kunci : interaksi antar makhluk hidup, keterampilan proses sains, LKS berbasis inkuiri terbimbin
