Efforts that can be made to overcome these problems are by applying the Contextual Teaching and Learning (CTL) model. The purpose of this study was to see the effect of the CTL model on the 21st Century skills of students. This research is quasi-experimental research. The population of this study were students of class X SMAN 12 Kerinci. Hypothesis test data analysis was carried out using the t-test. The results showed that the value of 21st Century skills of students in learning biology material, ecology and environmental change in the experimental class was higher than the control class. The average value of 21st Century skills of students which includes (a) Critical thinking skills in the experimental class were obtained 72.04 while the control class was obtained 61.13. (b) Communication skills in the experimental class obtained 75.90 while the control class obtained 68.06.
