The aim of this study is to examine negative effects of using WhatsApp social network application in educational processes and to create a conceptual framework in this manner. In order to examine the literature related to the research topic, sources in different databases were evaluated and research works after especially 2010 have been considered accordingly. A holistic framework regarding negative results of using WhatsApp in education has been tried to be established by examining the sources in detail. There is currently not too many scientific research works on benefits and disadvantages of using WhatsApp in long-term. But since this application has been accepted by many researchers as an instant messaging approach, it appears to be a small number of studies analyzing the effects of over-use of instant messaging take place in the associated literature. When the data obtained within this research is examined it is possible to express that the students addicted to instant messaging are inadequate in academic processes, they cannot control the time spent for messaging, they neglect their homework and they are also less disciplined compared to other students. Additionally, it is also seen these students' comprehension levels, learning skills, productivity and academic achievements have been affected negatively. It is also remarkable that students using instant messaging during reading tasks can increase the time required for completing reading, and may even feel sleepiness during daytime.
