The present study explores the impact of corpus-based collocation instruction on intermediate Iranian EFL learners' writing ability. For this study, 84 Iranian learners, studying English as a foreign language in Bayan Institute, Iran, were selected and were randomly divided into two groups, experimental and control. Conventional methods of writing instruction were taught to the control group while the experimental group received corpus-based collocation instruction in writing essays for 15 sessions. The design of the research was based on pre- and posttest method. The tests were employed to measure the writing fluency of the two groups. Test results were scrutinized to answer a major question for correlation between the participants’ variety of corpus-based collocations and their writing. The results illustrated that there was a significant difference between the mean scores of control and experimental groups in writing elements (p<0.05). Actually, lexical collocation instruction expanded the writing elements of vocabulary and mechanics rather than grammar and fluency in writing essays. The study findings indicated that there is a significantly positive correlation between the participants’ use of various lexical collocations and their writing proficiency.

This study focused mainly on the shifts of the grammatical cohesion in texts translated from English into Persian. It aimed to identify the grammatical cohesive devices (GCDs) in ST and TT separately, based on Halliday and Hassn's Model (1976), determine the number of occurrences of GCDs in two texts and finally, illustrate types of shifts of grammatical cohesion and strategies used in TT. To achieve these aims, a mixed-method (comparative and descriptive model) research design was used to spot cohesive shifts in TT due to translation, together with the employed strategies. To this purpose, the book, Oral Reproduction of Stories was investigated, with its translation. 39 different stories by different writers were selected as the sample of analysis. The results showed that the TT adopted all the three types of GCDs except verbal and casual substitution, with verbal substitution in Persian being carried down by reference, ellipsis and lexical cohesion. The occurrence of GCDs in the TT was more frequent than that of ST. Regarding the general analysis of the cohesion shifts, the study showed that three types of shifts (i.e. establishment of new cohesion, elimination of cohesion and change of type of cohesive features) occur in translation. Finally it was revealed that the translation strategies undertaken by the various translators are motivated and influenced by three factors (i. e. systemic language differences Baker (1992), stylistic preferences and the translation process itself (Blum- Kulka, 1986).

The present study investigated the effect of blended online and face-to-face instruction on the use of reading strategies by Iranian EFL learners. Out of 100 pre-selected learners, 60 homogeneous participants were identified as intermediate, according to their scores on the Oxford Placement Test. The participants were assigned to experimental (n=30) and control (n=30) groups. Then, a pretest was administered to assess participants’ current knowledge of reading comprehension. Both groups received a 7-session reading instruction. Whereas the experimental group was subjected to blended online environment where they could take advantage of Nicenet platform, the participants in the control group received materials, instruction and feedback through traditional methods in the classroom. After the experiment, the participants were required to take a reading comprehension test similar pretest as the post-test. In order to compare the frequency of reading strategy use by the experimental and control groups, the participants in the two groups were asked to fill out the Reading Strategies Questionnaire both before and after the experiment. The results of t-test between pre- and post-test showed that there is a significant difference between the experimental group and the control group in using the reading strategies.The findings of this study could help EFL teachers and syllabus designers gain insights into the processes learners go through when reading.

Task-based language teaching is considered an effective way to achieve a harmony between grammar and communication. The present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. To this purpose, an Oxford Placement Test was administered to select 40 homogeneous participants out of a larger population who took this test. The selected participants were randomly divided into experimental and control groups of 20 students each. Those in the experimental group attended an English class six days a week, practicing grammar through tasked-based approach, while the control group did not receive any task-based work. The OPT was administered at the end of the semester again to see which group could do modal verbs better. A final test of modal verb tasks was also administered at the end of the study to see if all the learners have improved in using modal verbs in the same way/at the same amount through task-based language teaching. The results of this study indicated that there is a statistically significant difference between the experimental group and the control group, meaning that teaching modal verbs through task-based approaches has been more effective than teaching them in traditional ways. It was also revealed that the modal verb can was improved much more, while have to and must were improved less. The results of the study may have a significant implication for teaching modal verbs in particular and language learning in general.

The present study attempted to investigate the impact of cooperation versus collaboration on college students` reading ability. To fulfill the purpose of the study, 90 participants were chosen from among 140 by means of administering the Nelson Proficiency Test. They were divided into three groups: cooperative group, collaborative group, and control group. A fifty-item multiple-choice reading vocabulary test was developed, validated, and used as the pretest. The results of the one-way ANOVA showed that there was no significant difference among the groups. Then after a number of cooperative and collaborative strategies used as the treatment in this study in six sessions of ninety minutes for each experimental group class, (control group without treatment) the posttest, which resembled the pretest in many respects, was administered to the three groups. The results of one-way ANOVA and Scheffee Test showed that the cooperative and collaborative groups worked better than the control group, and the collaborative one performed best.

In this study, the researcher used the many-facet Rasch measurement model (MFRM) to detect two pervasive rater errors among peer-assessors rating EFL essays. The researcher also compared the ratings of peer-assessors to those of teacher assessors to gain a clearer understanding of the ratings of peer-assessors. To that end, the researcher used a fully crossed design in which all peer-assessors rated all the essays MA students enrolled in two Advanced Writing classes in two private universities in Iran wrote. The peer-assessors used a 6-point analytic rating scale to evaluate the essays on 15 assessment criteria. The results of Facets analyses showed that, as a group, peer-assessors did not show central tendency effect and halo effect; however, individual peer-assessors showed varying degrees of central tendency effect and halo effect. Further, the ratings of peer-assessors and those of teacher assessors were not statistically significantly different
