The research instrument is a test sheet consisting of 10 description questions. Students creative thinking skills were analysed by answering the creative thinking skills instrument, which contained four indicators, namely fluency, flexibility, originality, and elaboration. Differences in the value of students creative thinking skills were analysed using N-gain when pre-test and post-test scores. The results showed that each component of students creative thinking skills experienced an increase between the pre-test and post-test scores. 36% of students get an N-gain score in the high category, while the remaining 64% are included in the medium category in the 1st replication class. 24% of students get an N-gain score in the high category, while the remaining 76% are included in the medium category in the 2nd replication class.
