Abstract
Abstract. The aim of this study are to know the effectiveness of the corrective formative evaluation on the ability to understand geometric concepts of the studens. This research is a quasi experimental study with sample thirty two students. The data was analyzed by using covariance analysis with students- initial ability as covariate. The results of the study show corrective formative evaluation give effective constribution on the ability to understand geometric concepts with a contribution 44.5%. This study also indicates there is a significant effect of students initial ability as covariate on the ability to understand geometric concepts 35.2%. The average the ability to understand geometric concepts of the students taught with corrective formative evaluations is higher than conventional classes.
