The objectives of this study are to find out: (1) the effect of SAVI approach on students’ activity, (2) the effect of SAVI approach on students’ learning outcome, and (3) the effect of SAVI approach on students’ retention in human regulatory system topic. A quasi experimental research with post test only control group design was used in this study. The population of this study was all of grade XI IPA students of SMA Negeri 1 Tebing Tinggi. There were 2 classes chosen as the sample by applying cluster random sampling technique. Experimental class was taught by SAVI approach while control class was taught by traditional approach.

It can be concluded that there is an effect of SAVI approach on students’ learning outcome. Learning outcome of students that taught with SAVI approach showed better results than students that taught with traditional approach.
