Abstract :In this research, interactive multimedia on thermodynamic concepts was developed and tested. The purpose of this research was to assess the effectiveness of interactive multimedia through a problem-based learning approach to students’ critical thinking disposition. The research development had three stages: preliminary study, development, and field testing. The field testing was a quasi-experiment with a pretest and posttest control group design. The research subjects consisted of four lecturers as expert validators, two teachers and two groups of 65 students in a high school in Mataram city, Indonesia. Data were gathered by using questionnaires, observation, interviews, and written test. The results of the Normalized-gain test were 53.1 for the experiment group and 52.2 for the control group. This shows that there were differences in the increase of students` critical thinking dispositions between the control group and the experiment group. Therefore, it can be concluded that the application of interactive multimedia could improve students` critical thinking dispositions.
