The results showed that learning the STEM approach with the flipped classroom strategy was able to improve students' system thinking skills, this can be seen from the average N-gain value in the experimental class of 0.65, which is greater than the control class with an average N-gain value of 0.55 with medium category. This shows that the system thinking ability of the experimental class is more improved than the control class. Also, supported by data from the results of the Independent simple T-test hypothesis test, the Sig value is obtained.
