PENGARUH SCIENTIFIC APPROACH DENGAN MODEL PROBLEMBASED LEARNING (PBL) BERBANTUAN APLIKASI INTERNETTERHADAP KETERAMPILAN PROSES SAINS SISWA SMA KELAS X PADA KONSEP EKOSISTEM

This study aim to examine the effect of scientific approach with Problem Based Learning (PBL) models assisted by internet applications on the concept of ecosystems. This type of research is Pre-experimental research design that is one group pretest-posttest design. The population in this study were students of SMAN 4 Sukabumi City in the second semester of the 2019-2020 school year. The instruments used in this study included 26 students 'process skills test questions, and questionnaire assistance to see students' responses to the use of scientific approaches with problem based learning (PBL) models for science process skills. The results of the normality test show that the pretest values are normally distributed and the posttest values are normally distributed and the homogeneity test shows that the data have homogeneous variants. Therefore hypothesis testing is done by parametric tests (Paired Sample t test Test). In the Paired Sample t test test if the Asymp.Sig value 0.05 then the hypothesis H0 is accepted and H1 is rejected. Paired Sample t test test results showed a P-value Sig (2-tailed) = 0,000. These results indicate that the P-value 0.05 then the hypothesis H0 is accepted and H1 is rejected. Paired Sample t test test results showed a P-value Sig (2-tailed) = 0,000. These results indicate that the P-value <0.05 so that H0 is rejected and H1 is accepted. Associated with significant differences before consulting and after being given. The conclusion of this study is that there is a scientific approach to the Problem Based Learning (PBL) model assisted by internet applications on the process skills of high school students in class X on the concept of ecosystem.
