The application of the problem based introduction model assisted by Bertis cards improves critical thinking of material balance and rotational dynamics

Abstract

The purpose of this study is to see whether applying a problem based introduction learning model assisted by a Bertis card can improve critical thinking and how improvements occur in that class. Then see the difference in an increase in critical thinking in the experimental class with a model based on introduction assisted by Bertis cards compared with the control class with the treatment of the problem based introduction model only. The research method used was a quasi-experimental research method. The study population this time was students of  SMAN 1 Pabuaran Serang. The results obtained are an increase in critical thinking in the experimental class can be quite good, seen from the N-gain value of  0.31 in the medium category. Besides that the experimental class was better in improving critical thinking than the control class. Judging from t arithmetic greater than than t table from the t test that has been done reveals that the increase in critical thinking in the experimental class is better than the control class.
