This research aims to describe the effectiveness of multiple representation based-student worksheets in improving students’ critical thinking skills. The research method used is a quasi-experiment by using pretest-posttest design. This research was conducted in one of the Lampung provincial junior high schools. The sample in this study amounted to 58 students consisting of two experimental classes obtained by using a purposive sampling technique. The data was gained by using questionnaire and test, and it analyzed by using paired sample t-test to investigate the effectiveness of the learning method in both groups of samples. The proposed methods show that there were differences of pretest and posttest score between the first and second experiment class as well as the size effect. Furthermore, students also give good responses to the learning process by using students’ worksheet based on multiple representations. For all test cases, the experimental results imply that Multiple Representation-based Student Worksheet is one of the effective ways of improving students’ critical thinking skills in the inheritance properties topic. This is evidenced by an average increase in all significant critical thinking indicators, especially indicators that advance clarification in the high category.
