Abstract
In the 2005/2006 academic sessions, the Faculty of Engineering at the Universiti Kebangsaan Malaysia, started implementing the outcome based educations (OBE) approach beginning with the first year courses. As to observe the effectiveness of the OBE approach, this study is conducted. The aim of this study is to evaluate first year students' performance before and after the implementation of the OBE approach. In this study, the overall performance measured quantitatively using the grade point average (GPA) achieved by the first year engineering student of groups before and after the implementation of the OBE approach. Statistical analysis was done to identify the impact of the OBE approach on students' performance. Comparisons made with results obtained from previous studies revealed some interesting observations.
