Abstract

An objective of this study was to investigate the effect of multiple representations approach in learning physics to the cognitive skills of students at SMA Negeri 1 Anjongan on momentum and impuls. The form of research used quasi-experimental design with pretest-posttest control group design. The saturation sampling technique was used to investigate the sample. The sample was two classes with one class as an experimental class and one class as a control class. This study used 5 question essays as an instrument to measure students’cognitive skills in the pretest-posttest while responses of student about multiple representations are used a questionnaire. The results of data showed that the increase in cognitive skillss of the experimental class students obtained N-Gain value of 0.44 which was categorized as moderate and in the control class the value of the N-Gain of 0.23 was categorized as low. The statistical test ( =-5.89) showed that there are differences in cognitive skills of students (α= 5%) between students who are given learning with a multiple representations approach and students who are given learning with the usual learning approach. Students gave high response  about the learning multiple representations with  a percentage of the total response 82.23%.
