Abstract: Learning in Industrial Revolution Era 4.0 is plotted to integrate the use of technology and information optimally. The optimal use of technology and information is intended to develop students’ critical thinking skills. However, it is known that the use of media in economics learning in high school is still not optimal, so students' critical thinking skills are not optimally developed. This study aims to examine the impact of the use of adobe flash media in improving students' critical thinking skills. The study employed the quasi-experimental research method, and cluster random sampling is used to determine the experimental group and the control group. The results of this study demonstrate that adobe flash media has a significant effect on increasing students' critical thinking skills in economic learning. It is indicated by the acquisition of t = 0, 000 with a significance level of <0.05. Furthermore, the average critical thinking ability of students in the experimental class increased by 22 points after learning using adobe flash media. In addition, the average critical thinking ability of students in the experimental class was 8 points higher than the students in the control class.

Keywords: Critical Thinking Skills, Adobe Flash Media.
