Abstract
The implementation of less effective learning models causes low student chemistry learning outcomes, so a learning model that involves students is needed to be active and independent. In this study, the Flex model Blended Learning was applied which can improve learning outcomes on acid and base. The research method used is Quasi Experimental with Nonequivalent Group Pretest Posttest Design. The results showed there was an increase in chemistry learning outcomes on acid and base at SMA Negeri 4 Pekanbaru. The data analysis techniques used are parametric tests in the form of normality tests, homogeneity test, N-Gain tests, and hypothesis tests. The results of the analysis showed that the data obtained were normally distributed and homogeneous. After obtaining normal and homogeneous distributed data, the N-Gain test is carried out. The N-Gain value has been obtained, then hypothesis test is carried out. The results of the hypothesis test showed an increase in learning outcomes after the implementation of the Flex Blended Learning model on acid and base.
