Very few research papers and case studies have shown successful integration of both Facebook and Moodle in the educational experience of students. This study sought to evaluate the educational benefits of the increasingly popular Facebook--which plays an important role in students' social life as well as their academic life--and to compare it with the widely used course management system Moodle. In this study, the authors surveyed students of the University of Belgrade's Faculty of Organizational Science in Serbia on their attitude toward Facebook and Moodle as productive online tools for teaching and learning. An analysis of the results was carried out using the SPSS software package. The results of this research answer the question of whether or not using Facebook as an educational tool is more effective than using Moodle and how it affects students' everyday learning activities.
