Abstract

Application of problem based instruction’s model in science about food additive and its relation with healthy have purpose to describe feasibility of RPP IPA, student activity, student result, and student responses during and after study. In this study, used two class, are experiment class which use problem based instruction’s model and the other class use guided discovery’s model. Analyze of data with t’ test show result that application produce different average of study result. From calculating, different average of study result experiment class and control class, t is 10, 70 and than that result have compared with t of table with 5% signification as 1,668. These results show that t’ calculate bigger than t table so zero’s hypothesis is rejected. Beside that, the result examined again with right t test and got t as 10.70, this result bigger than t as 1, 69 so zero’s hypothesis is rejected again. The meaning is application of problem based instruction’s model give average of study result higher than guided discovery’s model. This study conclusion is application of problem based instruction’s model give average of study result higher than guided discovery’s model.

Keywords: problem based instruction’s model, guided discovery’s model.
