In this research, the purpose was to examine and compare the effect of teaching Electric Current, which is a topic of grade 11 physics lesson, on student achievement and attitude according to the 5E model belonging to the constructivist learning theory and the traditional teaching method. The research was conducted in the spring semester of 2009-2010 academic year with 62 students who were attending the 11th grade. The quasi-experimental method was used in the research and the significance level was p = 0.05. A meaningful difference (p<0.05) was observed on behalf of the experimental group according to the results of the independent samples t-test related to the post-test scores of "Electric Current Achievement Test (ECAT)" of the students in the experimental and control groups. It was concluded that the worksheets applied, cartoons, animation and laboratory activities used while teaching the topic "Electric Current" according to the 5E model provided better understanding by students, increased the motivation related to the lesson, created a positive effect on understanding abstract concepts. The results of the attitude scale showed that the differences between the groups were insignificant (p>0.05).
