Teaching grammar is a process, which has been a problem for many language teachers around the world. Considering the results revealed in the previous studies, this problem places itself especially in English for Specific Purposes (ESP) classes. The aim of this action research is to search for probable effects of videos to be used to teach grammar explicitly in an ESP grammar class. Since the students do not want to use traditional course books and get bored with the activities that are not related with the context and their aims, the present study deals with the use of technology in an ESP class.
