Investigating the Implementation of Interjections in Three Current EFL Course Books

Abstract The purpose of this study is to investigate interjections’ frequency of use in three different EFL course books. To this aim, the Student's Book and Teacher's Edition of Interchange 3, Top Notch 3A and 3B, and Touchstone Intermediate were examined. All the above books were studied carefully and the applied interjections were identified. Then the frequency of use of interjections in different units of each book and different parts of each unit was computed. The findings of this study revealed that Touchstone course book had the maximum number of interjections (607). The Interchange and Top Notch course books, each with 427 and 330 interjections, took the next places in frequency. It was also found out that interjections were not evenly distributed among different units of each book. Furthermore, most of interjections were concentrated in the Listening and Conversation Sections in the units. ‘Well’, ‘oh’, and ‘yes’ were among the most frequently used interjections and ‘good grief’, ‘yuck’ and some others were among the least frequently used ones. This study has some implications for EFL material developers, teachers and students.
