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.

This article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of English as a foreign language (EFL). The study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was affected and to investigate possible overlaps between EFL learners’ perceptions of task difficulty and hypothesized task complexity. A purposive sample of 54 first-year EFL learners randomly assigned to two parallel conversation classes in an English department of a major public university participated in the study and performed listening tasks in a language lab. The instruments used for data collection were seven tasks taken from a TOEFL Test Preparation Kit, each followed by listening comprehension questions and an item on the participants’ personal perception of the difficulty of the task. During counter-balanced administrations, the tasks were manipulated for one of the four dimensions of task difficulty (adequacy, immediacy, perspective, and prior knowledge). The resulting data included the participants’ perception of difficulty as well as their performance scores under less complex and more complex conditions. One-sample T-test and correlation analyses of the data revealed that for all of the four complexity dimensions, the hypothesized less complex task condition led to better learner performance. The correlation between learner-assigned difficulty score for the task at hand and theoretical task complexity level was significant only for the immediacy dimension (r=-0.67, p<.05). The results offer support for task complexity frameworks, raise doubts about learners’ perceptions of tasks, and imply possibilities for task manipulation in language learning contexts.
