This study investigated the type and frequency of metadiscourse markers used in fifty research articles written by Saudi EFL college students. In analyzing the data, Hyland's (2005) model of metadiscourse was adopted. The findings showed that there are significant differences in the frequency of interactive and interactional metadiscourse. The students employed more interactive metadiscourse markers than interactional ones. The analysis further revealed that transitions occurred most often in the research articles, followed by hedges. The least used metadiscourse markers were endophoric markers and attitude markers. To conclude, some pedagogical implications for teaching English writing to Saudi EFL college students were drawn from these findings. It can be noted that Saudi EFL college students need more training in using interactional metadiscourse to be able to convince the reader of their ideas and arguments in a text. In addition, they must be more aware of the importance of using metadiscourse in improving their writing skills in general.
