The sampling technique in this research used cluster random class, the experimental class used collaborative inquiry learning model and control class using conventional learning. The variables in the study consisted of 4C skills as dependent variables and collaborative inquiry models as independent variables. The data in this study were analyzed using one-party t-test. The results showed that students '4C skills with collaborative inquiry learning models were better than students' 4C skills with conventional learning.
