This study, on the one hand, investigated whether or not strategies like Lexical Inferencing (LI) and Morphological Instruction (MI) can significantly affect English as a Foreign Language (EFL)learners’ reading comprehension, and on the other hand, it examined their effects on the learners’ vocabulary retention over time. For this purpose, 60 homogeneous EFLlearners were randomly assigned to two experimental and one control group each one consisting of 20 participants. After the pre-test, participants of the first experimental group received lexical inferencing strategy training for six 45-minute sessions. The second experimental group was also provided with morphological instruction for six 45-minute sessions and as for the control group, the participants followed their regular reading comprehension course without any specific strategy training. After the treatment, two post- tests with a short time interval were administered to the three groups and the obtained data were fed to different statistical tests to spot the probable differences among the three groups' first post- test performance as a measure of their learning differences and the second post-test performance as a measure of the learners’ vocabulary retention differences over time. Results of the paired t-tests for comparison of the within group differences showed that lexical inferencing instruction had statistically significant effect on EFL learners' reading comprehension development. On the other hand, it was found that morphological instruction had no statistically significant effect on EFL learners' reading comprehension development. The ANOVA analyses revealed that there was no statistically significant difference between the effects of lexical inferencing and morphological instruction on EFL learners' reading comprehension development. Furthermore, no significant difference was found between the effects of lexical inferencing and morphological instruction on EFL learners' reading comprehension development over time.

The purpose of this study was to probe the effect of metacognitive strategy instruction through dialogic interaction on the reading comprehension performance and metacognitive awareness of Iranian EFL learners. The data were collected through the Survey of Reading Strategies (SORS) and a reading test to examine changes in metacognitive awareness and reading performance before and after the intervention. The participants were 60 intermediate EFL learners in two groups. The experimental group (n = 30) went through an intervention program in which the learners were taught metacognitive strategy instruction through dialogic interaction for ten sessions. The control group (n=30) went through a conventional reading instruction program and covered the same materials without receiving metacognitive instruction. The results revealed that metacognitive strategy instruction through dialogic interaction helped learners develop their reading ability and raise their metacognitive awareness.

Oral Communication Strategies are conscious techniques that L2 interlocutors employ to overcome the communication breakdowns in the target language. Hence, they can help to promote the effectiveness of communication ability. However, it must be noted that many variables can influence the use of these strategies. The present study, therefore, aimed to investigate the role of language proficiency and cultural background variables on the use of oral communication strategies. After piloting the Oral Communication Strategy Inventory and Cultural Milieu and examining the reliability analysis as well as the construct validity, the questionnaires were administered to 320 participants majoring in the English language at B.A and M.A levels. Then, SPSS 18.0 computer program was used to analyze the collected data. Next, an interview was held to gain more information on the use of strategies by the Iranian EFL learners. The results of this inquiry revealed that there is no significant difference between learners at different language proficiency levels in terms of oral communication strategies use, while there is a significant difference between different cultural backgrounds in the use of OCSs. The findings of this research can be useful for developing the use of oral communication strategies among EFL learners, particularly with Persian and Turkish cultural backgrounds.

Research articles have received a wide interest in discourse studies particularly in genre analysis over the last few decades. A vast number of studies have been centered on identifying the organizational patterns of research articles in various fields. While Introduction section has enjoyed a lot of attention, very few studies have focused on rhetorical structure of qualitative and quantitative research articles. This genre-based investigation reports on a study of the Introduction sections of 15 qualitative and 15 quantitative research articles in Applied Linguistics from five high impact journals published from 2008-2012. Based on Swales’ (2004) move structure model, this study focuses on Move 3 (introducing the present work) and examines how qualitative and quantitative research article writers introduce their work in Introduction section. The analysis revealed that there were similarities in the overall presence and use of steps in both groups, some differences in the overall presence and frequency of directive determinants were obvious which could be attributed to the different nature of these research designs.

Although English language plays an important role in the job of aviation personnel, language needs of these employees have been taken for granted. This study aimed at investigating the extent to which English is used by the employees at Iran Air airport services at Isfahan Airport, the required level of basic language skills in performing their jobs effectively, and the employees’ attitude towards their English professional courses. A questionnaire consisting of 24 items was constructed and distributed among all the employees working at three sections of Iran Air airport services (Ramp Control, Customer Services, and Baggage Services). Besides, Observation was done by the researcher at the airport to find out the basic language problems of the aviation personnel, and interviews were done with the head of each sections. The findings proved that English language is highly used in the employees’ jobs and they are not satisfied with their training courses. Also, the Ramp Control and Baggage Services employees considered speaking as the most important skill, while Baggage Services employees considered reading and writing as the important ones. Finally, it can be concluded that revision of the current professional training programs seems to be necessary to offer appropriate ESP course curriculum.
