The Effect of Problem Based Learning Model based on SAVI toward Student Higher Order Thinking Skills and Science Process Skills at Coordination System Subject in SMA Negeri 1 Aek Kuo

This research aimed to determinate the effect of PBL based on SAVI toward Higher Order Thinking Skills and Science Process Skills at Coordination System Subject in SMA Negeri 1 Aek Kuo. A quasi experimental research used a randomized pretest-posttest control group design. The sampling technique was total sampling, namely experiment class 1 using PBL model based on SAVI, experiment class 2 using PBL model, and experiment class 3 using conventional. The number of samples was 69 students. The techniques test was used in data collection. Higher order thinking skills and science process skill were analyzed by covariate analysis (Anacova) and further Tukey’s test with a significant level  = 0,05. Anacova results showed that there was significant effect by the PBL model based on SAVI, PBL, and conventional toward higher order thinking skills (F = 12,61; P= 0,000) and science process skills (F=11,70; P= 0,000). The posttest average of student higher order thinking skills and science process skills with PBL based on SAVI was higher compared to PBL and conventional learning.
