Abstract

This research aims to see differences in students' conceptual understanding of the reaction rate material as the result of LC 5E-Analogy learning model. LC 5E-Analogy is related to double coding theory, information received by learner is obtained through one of two channels, where LC 5E is expected to facilitate students to obtain information from the enggament phase to the elaboration phase, while the analogy is expected to visualize the submicroscopic aspect, so as to improve understanding of concepts students. This study uses a reasoned multiple choice test instrument that has 91% content validity with a very good category and a reliability coefficient of 0.799 in the high category. The research was conducted in two classes of XI Science at SMAN 9 Malang. Analysis of the data using the Man Whitney U Test, and the Effect Size test to see the meaning of differences in understanding of students' concepts. The results showed that there were differences students understanding in both research classes, where the difference in the values of the two classes (Sig.2-tailed 0.002) and the Effect Size (d = 0.74).
