This study aimed to investigate the use of interactional metadiscourse markers in 168 comments made by 28 university students of engineering via an educational forum held as part of a general English course. The students wrote their comments on six topics, with a total of 19,671 words. Their comments during educational discussions were analyzed to determine their use of five metadiscourse categories (hedges, boosters, attitude markers, engagement markers, and self-mentions), making up interactional metadiscourse in Hyland’s (2004) model. Following descriptive analysis of the use of metadiscourse categories, chi-square tests were used to investigate the possible differences in the whole sample as well as gender-based differences. The findings showed that although female EFL learners used more metadiscourse markers than males did, the differences were minor and hence gender did not significantly influence the use of interactional metadiscourse markers. However, while male and female participants used all types of interactional metadiscourse, how they used them varied. They used engagement markers and self-mentions more frequently than boosters, hedges, and attitude markers. Since metadiscourse markers play crucial roles in mediating the relationship between what writers intend to argue and their discourse communities, the results of the present study have obvious importance in increasing students’ awareness of the way they organize their writings.
