Abstract
This study aims to determine the effect of the Problem-Based Learning model on students’ critical thinking skills with multi-representation approach on buffer solution concept. The research applied an experimental research method. This type of research is quite experimental. The design used in this study is a non-equivalent control group design. The population in this study were all students of XI IPA. Samples were taken using a purposive sampling technique and involved students of class XI IPA 1 and XI IPA 2. The researcher conducted an essay test with five questions that had been examined for validity and reliability to determine the effect of the problem-based learning model on students’ critical thinking skills with multi-representation approach of the buffer solution concept. The hypothesis testing uses a t-test and obtains a value of tcount = 4.98 > ttable = 1.67655. Thus, Ho is rejected, and Ha is accepted. In conclusion, there is an effect of the problem-based learning model on students’ critical thinking skills with multi-representation approach on the buffer solution concept.
