The effect of the REACT CBA strategy on the material of reaction rate on student achievement at SMA Kristen 1 Tomohon

Abstract

Abstract The purpose of this study was to determine whether there was an effect of the REACT CBA strategy on the material reaction rate on student achievement at SMA Kristen 1 Tomohon. The REACT CBA strategy was applied in the experimental class with 33 student’s in number, and conventinal learning in the control class with 33 student’s. Studen achievement scores are obtained from the pretest and posttest scores. The results showed that there was no significant difference in the pretest scores of the experimental and control class, namely U = 543,5; p = 0,990 (p > 0,05). While for the posttest scores there is a significant difference between the experimental and control classes where U = 151,0; p = 0,000 (p = < 0,05). So that the conclusion is that H0 is rejected and H1 is accepted, it means that there is an effect of the material reaction rate on student achievement.
