Abstract
Abstract This study aims to test the effectiveness of the causalitic model learning device to improve students’ creative thinking ability and problem-solving. The design of this study was a one group pre-test and post-test design with a purposive sampling technique so that 15 students were obtained. The research instruments used were lesson plans, preliminary assignments, student worksheets, with data collection tools in the form of tests of creative thinking ability and problem-solving. Data were analyzed using calculation of N-Gain.Thus, the implementation of causal learning tools to improve creative thinking skills and physics problem-solving students is effectively used in learning.For further researchers, it is necessary to increase the frequency or duration of learning so that students can better understand learning.
