This study tested the impact of implicit and explicit knowledge of grammar on learners’ use of oral communication strategies (OCSs) and the interface of OCSs and oral fluency. The study was performed on 24 male and 36 female Iranian university students of English Translation studying at Payame Nour Universities of Lar, Khonj, and Evaz chosen based on availability and ease of access. The data were gathered using Timed Grammaticality Judgement Test (Dekeyser, 2000) as a measure of implicit knowledge of grammar, a structure section of TOEFL Paper-based Test (version 2004) as a measure of explicit knowledge of grammar, Oral Communication Strategies Inventory (Nakatani, 2006), and two oral production tasks for measuring learners' oral fluency. Analysis of the data using Multivariate Analysis of Variance (MANOVA) and Pearson’s Correlation showed that both implicit and explicit knowledge of grammar affect learners’ use of oral communication strategies; however, no relationship was found between overall use of OCSs and oral fluency which can be suggestive of greater or possibly overriding impacts of some other variables on oral fluency compared to OCSs. The findings of the study are supposed to provide guidelines for learners, teachers and syllabus designers concerning the use of OCSs, especially with regard to other variables considered in this study.

Building on Robinson’s (2001, 2003) Cognition Hypothesis, Skehan’s (1998) Limited Attentional Capacity Model, and Kellog’s (1986) model of writing, this study examined the effect of task planning on the fluency, accuracy, and complexity of 60 Iranian EFL learners’ argumentative and narrative writings under different planning conditions. A quasi-experimental design with three levels of planning conditions (pre-task planning, within-task planning and no-planning) and different time constraints was used. Measures of fluency, accuracy, and complexity were used to evaluate the quality of the participants’ written productions. The results of a series of one way Multivariate Analyses of Variance (MANOVAs) indicated that increasing task complexity, through task planning conditions and also different tasks produced significant differences among the groups in fluency and accuracy; however, with regard to syntactic complexity, both tasks provided similar results among the groups. The findings add support to the view that selecting an appropriate task with appropriate task-based implementation conditions can induce language learners to increase, accuracy and fluency, but not syntactic complexity of their output. Pedagogical implications are discussed and suggestions for further studies are made.

Advertisement has long been used as a tool for informing and attracting audiences in different ways. This study aims at investigating the linguistic tools of advertisement in Persian on the basis of Halliday’s systemic-functional grammar theory. The data of this study were gathered from written and verbal commercial advertisements which were recorded and rewritten in order to investigate verbal groups in the sentences in terms of process and function types and subsequently compare the two bodies. The results showed that material and relational processes had highest frequency in Persian language in terms of ideational metafunction. From the interpersonal metafunction perspective, information function was frequent in most cases. Regarding these factors, there was no significant difference between verbal and written bodies.

Speaking is a significant skill that many foreign language learners are trying to master. In this study, the effectiveness of two different speaking activities, i.e. oral presentation vs. free discussion, was investigated from quantitative and qualitative points of view. To achieve this purpose, 44 intermediate learners from a language institute in Tehran participated in the study. Half of the participants experienced oral presentation while the other half (22 in two other classes) experienced free discussion for eight sessions. The two activities were exchanged between the two groups after the end of the quantitative phase of the study for eight more sessions. The results of an independent samples t-test performed on the scores ofthe speaking section of a sample Preliminary English Test (PET, 2012 ) after the first phase of the study (the first 8 sessions) indicated that the learners who experienced oral presentation significantly outperformed the learners who experienced free discussion though both activities proved to be significantly useful. Furthermore, the results of the interview with 10 participants from each activity through purposeful sampling, after the second phase of the study (the second 8 sessions) through thematic analysis indicated that both free discussion and oral presentation activities had some merits and demerits. Based on the results it can be advisable to include the two activities as complementary.
