The study of lexical bundles, among types of text analysis, is gaining importance over the others in the last century. The present study employed a frequency-based analysis approach to the use of lexical bundles. The discussion section of 60 political science articles, with corpora around 253,063 words were investigated in three aspects of structure, form, and function of lexical bundles. The present study selected its data pool out of scholarly articles from qualified journals in the field of political sciences. One part of the data pool was made up of 30 articles written by American native speakers. The second half of the data comprised the 30 articles written by Iranian scholars in political sciences. The findings showed that native and Persian-speaking writers employed the same forms of lexical bundles, and there were significant differences concerning the nativeness and functions. Bearing in mind the findings of the present study, material developers would think of the possibility of the addition of lexical clusters into the materials. It can similarly be valuable for the development of the second language writing strategies, for those who need to write in academic contexts especially political contexts.

Test method facet is one of the factors which can have an influence on the test takers’ performance. The purpose of the current study was to investigate the effects of two different response types, multiple-choice cloze and multiple-choice test, on the pre-intermediate and intermediate test takers’ reading comprehension performance. To this end, 40 pre-intermediate and intermediate learners participated in the study. To counterbalance the practice effect, the participants of the study at both pre-intermediate and intermediate levels were randomly assigned into two groups. For each level, there were two types of tests and two test administrations. Within each level, the two groups took these two tests in a different order. For all participants of the study there were two scores based on multiple- choice cloze and multiple-choice tests. Two Paired sample t tests were separately run to compare the pre-intermediate and intermediate test takers’ performance on multiple-choice cloze and multiple-choice tests. Two independent samples t tests were run to compare the pre-intermediate and intermediate test takers on these two tests. There was no significant difference between the pre-intermediate test takers’ performance on these two types of tests. There was a significant difference between intermediate test takers’ performance on the tests. There was no significant difference between the pre-intermediate and intermediate test takers’ performance on the multiple-choice cloze tests. The intermediate test takers outperformed the pre-intermediate test takers only on the multiple-choice tests. Based on these results it can be concluded that test methods can have an influence on the test takers’ performance, especially at higher proficiency levels and learners may need to have reached a certain level of proficiency to be able to understand the text.

The present study investigates the effect of e-mail on Iranian learners of English and focuses on teaching thewriting skillvia e-mail. More specifically, the study investigates (a) whether using e-mail has any statistically significant effect on improving high school students' writing skill, and (b) whether the proficiency level has any relation with students’ writing improvement through using e-mail.To this end, 150 high school Iranian students were selected randomly and divided into 3 proficiency levels, namely high, mid, and low, based on their performances on an Oxford Placement Test (OPT). The participants at every proficiency level were divided into 3 subgroups to receive 3 methods of instruction, namely traditional face-to-face, through using e-mail, and through both the traditional method and using e-mail. After 3 months of instruction, a posttest was administered and the results were submitted to ANOVA. The results obtained revealed that using e-mail had a statistically significant effect on improving students' writing skills. The Scheffe post hoc results showed that the group with the e-mail treatment performed almost the same as the other 2 groups at the high proficiency level; in other words, the group at the high level did not benefit much from using e-mail; however, thelow and intermediate proficiency level participants did benefit from it. The findings are finally discussed with regard to how email can be exploited as an educational aid by teachers and learners.

Textbook evaluation serves as a useful tool at teachers‘ disposal to cope with uncertainty in opting for the proper material prior to embarking on their teaching career. This study aims at comparing two different ESP textbooks, one of them English for students of Mechanical Engineering, design of solids (SAMT publication), and the other one English in Mechanical Engineering (Oxford University Press). For the purpose of comparison and contrast, Textbook Evaluation Checklist (Miekley, 2005) was used against which the components of these two books were weighed to show what they have in common and where the point of departure from any commonality is. Although based on evaluative questions some inherent inefficiencies of these textbooks were revealed, it was generally concluded that both of them have tenable justification to be taught as an ESP course book.

این مقاله بر دانش فراکلامی متمرکز است، نامی که به اجزایی در متن داده می شود که معنا را منتقل می کنند نه آن دسته از اِلمان هایی که اساساً ارجاعی هستند. در این مقاله به پیش زمینه تئوری مطالعات فراکلامی اشاره می شود و بطور خلاصه طبقه بندی نشانه های فراکلامی بررسی شده و در آخر چهار دلیل برای اهمیت و جذابیت دانش فراکلامی ارائه می گردد: 1) این تحقیق نشان می دهد که زبان تا چه اندازه به صورت پیچیده ای نظام بند است. 2) در این مطالعه سوال های جالبی در ارتباط با اصول اخلاقی و استفاده زبان مطرح می شود. 3) این تحقیق، هم چنین به تفاوت های استفاده ی نشانه های فراکلامی در بافت های مشابه در زبان های متفاوت اشاره می کند. 4) و دراین مطالعه دلایلی فراهم خواهد شد که چرا دانش فراکلامی مستحق جایگاه ویژه ای در آموزش زبان دوم می باشد.
