Abstract

Improving the quality of education in Indonesia can be developed through the implementation of educational reform. One form of educational reform can be carried out by using a learning approach that can help teachers produce experts using the STEM (Science, Technology, Engineering, and Mathematics) approach. Initial findings reveal that only around 47.8% of SMA N 2 Medan students (class This research aims to see the effectiveness of the STEM approach in improving the critical thinking skills of SMA N 2 Medan students. The research method used is an experimental design with Non Equivalent Control Group Design. The research subjects were students of SMA N 2 Medan. The results showed that the sig (2-tailed) Equal variances value was assumed to be 0.000 < 0.05. Therefore, Ho is rejected and Ha is accepted, which means there is a significant difference in critical thinking abilities after students use the Equal variance method. The STEM-PBL approach, compared with the innovative K13 approach. The average critical thinking skills scores of the control class in the pre-test and post-test were 38 and 79.5. The coefficient remains at 0.676 and is significant at 0.000. This means the correlation is positive. Therefore, learning with a STEM approach has proven to be effective in improving the critical thinking skills of SMA N 2 Medan students.
