Being able to communicate effectively is the optimal goal of all language learners; therefore, despite difficulties they face and restrictions they have while expressing themselves, they rely on employing diverse communication strategies (CSs). This descriptive study was set to analyze Iranian EFL learners’ use of CSs in oral and written performances at two levels of proficiency. To this end, 60 university students of EFL were selected and assigned to two distinct groups. The participants’ oral and written performances were analyzed quantitatively and qualitatively using Dornyei’s (1995) taxonomy of CSs. The results of the study revealed that the context of communication plays a significant role in the use of communication strategies. The use of CSs by participants’ significantly varied by their level of proficiency. The most frequent problem areas were 'lexical gaps', 'problems in discourse management', and 'uncertainty in conveying the message', which can be considered by language teachers and material designers.

This study explored the effectiveness of the two computer-assisted modes: cooperative and individual on improving Iranian high school students’ reading comprehension. It was also concerned with investigating the effectiveness of the two computer-assisted modes on the participants’ foreign language learning anxiety (FLLA). The sample of the study consisted of two intact groups, each containing 24 students, which were randomly assigned into a control and an experimental group. The control group completed the study according to the individual computer-assisted learning while the experimental group was taught via computer-assisted cooperative language learning. The participants in the experimental and the control groups, which consisted of 48 female students, took reading comprehension pretest and posttest. They were also given foreign language classroom anxiety scale (FLCAS) questionnaire both at the beginning and at the end of the treatment. The collected data were analyzed using SPSS 16.0. The results of the independent and paired samples t tests indicated that the experimental group, in which cooperative learning was integrated into computer-assisted language learning, outperformed the control group in terms of reading comprehension. In addition, the level of foreign language anxiety improved after the treatment in the experimental group. The findings of this study provide some insights for teachers to consider the integrating of cooperative learning into computer-assisted language learning setting.

Mobile-Assisted Language Learning (MALL) is prevalent in English instruction to enhance students' learning interest and motivation. However, its effectiveness and practicality have rarely been well confirmed. The present study intended to investigate the effectiveness and practicality of utilizing a developed Mobile Learning Application (MLA) in listening instruction. A quasi-experimental design was applied in the study with a test and a questionnaire as research instruments. The pre-test and post-test were administered to examine the effects of administering MLA on 86 undergraduate students’ listening comprehension, and the questionnaire was employed to investigate 184 students’ perceptions of the practicality of MLA in mastering listening comprehension as data triangulation. Descriptive and inferential statistics were utilized to analyze the collected data. The results showed that a teacher-developed MLA is feasible for effective learning media to enhance students’ listening comprehension with the significant difference between pre-test and post-test scores. Moreover, it also accentuated that students' perception obtained a positive perception of the practicality of a developed MLA in mastering their listening comprehension. This finding encourages EFL teachers to use a mobile learning application in listening instruction to promote students’ independence in mastering listening skills.

The interaction between the writers and the experts while using citations is one of the main features of academic texts. For the integration of external experts into the text, writers usually use reporting verbs, which seem to function differently. Furthermore, selecting reporting verbs (RVs) by the researchers of disciplines seems to vary. This paper explored the functions of RVs across sciences. To this end, 200 “Results and Discussion” section of RAs from the four sciences, namely Life Sciences, Social Sciences and Humanities, Physical Sciences and Engineering, and Health Sciences were gathered and used as the data, and their functions of RVs were analyzed based on Hyland’s framework (2002). Hyland (2002) considered three basic RV types based on their function, including research, cognitive, and discourse acts, subsequently dividing each category into several subcategories. The results showed that the writers in Life Sciences used more research acts in comparison to the other disciplines. In terms of cognition acts, the rates of tentative verbs were high in all sciences since the researchers tried to report the results with caution as they were uncertain about the findings. The results approved this claim, indicating the high frequency of tentative verbs under the category of discourse acts, across disciplines using verbs like hypothesize, indicate, and suggest to show doubt with different rates. The obtained results can guide novice writers of the above-mentioned four disciplines to advance an authorial perspective and adjust to the expert conventions of the relevant research areas.

The current study aimed to explore the nature of discursive strategies academics would use to share their specialist knowledge to both specialists and non-specialists. To this end, a corpus of 40 academic research articles and 40 popular science articles were randomly selected from the archive of four English international peer-reviewed journals and four English popular magazines and newspapers in the field of Nutrition. Appraisal Theory (Martin & White, 2005), a discourse framework to examine evaluative and/or persuasive language, was used to analyze the data. The results revealed significant areas of similarity and difference in terms of certain discursive elements leading to discernible degrees of persuasion. The findings imply that in order to develop a scientifically literate society, scientists should appeal to diverse discourse resources to provide the public with their findings in an informative and entertaining way. The results of the study carry some pedagogical implications for EAP courses held in EFL settings since being able to both comprehend and produce scientific texts of different professional levels at international scale seems to be a requirement for the future scientists.
