In the study, which was performed in accordance with the descriptive scanning method in this research, primarily the papers, dissertations in magazines indexed in databases such as the Dissertation scanning center of the Board of Higher Education, Ebsco Host, Science Direct, Taylor and Francis and Web of Science etc. and the literature were scanned in a broad perspective. The dissertations, papers attained as a result of scanning were analysed by taking the grades of objective, conclusion and education into consideration. The 5E Model was developed by one of the leading names of the BSCS (Biological Science Curriculum Study) project, Rodger Bybee, and used in applications aimed at this project. The 5E Model grounds on the Constructivist Approach and the Model of Learning Ring. There is a good deal of ¡°E¡± release in the literature. These are encountered as 3E, 4E, 5E, 7E etc., however, this study analyses the 5E Model. The 5E Model is consisted of the grades of Engage, Explore, Explain, Elaborate, Evaluate %K Constructivist Approach %K 5E Model %K Physics Education and Teaching %U http://www.lajpe.org/mar12/4_LAJPE_620_Ismet_Ergin_preprint_corr_f.pdf
