In this study, the effect of the lessons applied in the subject of Inclined Projectile Motion, by taking the 5E Model as basis, in the Physics lesson of GATA Noncommissioned Health Officer Preparation School’s 1st grade, on students’ academic success and attitude levels was investigated. The study was carried out on 84 students studying in GATA Noncommissioned Health Officer Preparation School’s 1st grade on 2004-2005 spring semesters. In the study, multiple choice success test and attitude scale were used. At the analysis made at the end of the application, it was concluded that the experimentation group students on which the 5E Model had been applied were more successful than the control group students on which traditional method had been applied, and that they developed more positive attitudes towards the subject. In light of the findings obtained at the end of the study, recommendations were made.
