Today, rapid changes have been taking place at all levels of social structure as a result of the developments in communication and information technologies. Aiming at determining the factors that affect classroom teachers' application frequency of twelve communication barriers and the influence level of these barriers' application frequency on student's academic success, a descriptively qualified scanning model was used in this study. In the study, data were collected by using literature review and questionnaire technique within the framework of the general scanning model. The sampling of the research consists of 302 classroom teachers (Female: 180, Male: 122) who work in the 2013-2014 academic year in state and private schools located in Istanbul and were randomly selected. According to the findings, the need to behave carefully in communication is inevitable in the light of the data obtained from these studies.
