این تحقیق به بررسی تاثیر پیچیدگی زبان و اندازه گروه بر ساخت دانش در دو بحث آن لاین می پردازد. ساخت دانش از طریق مدل تجزیه ارتباطات Gunawardena و دیگران (۱۹۹۷) سنجیده شد. پیچیدگی زبان از طریق تقسیم تعداد کلمات خاص بر کل کلمات به دست آمده و به تغییر لغوی اشاره دارد. نتیجه این تحقیق نشان می دهد که ساخت دانش و اندازه گروه به طور چشمگیر و البته به شکلی منفی با هم مرتبط اند که بیان کننده این موضوع است که هر چه اندازه ی گروه کوچک تر باشد میزان ساخت دانش بالاتر می رود. نتایج همچنین نشان می دهد که ساخت دانش و پیچدیگی زبان به طور چشمگیر و مثبتی با هم مرتبط اند که مشخص کننده این موضوع است که هرچه تغیرات لغوی بالا تر باشد ساخت دانش نیز بالاتر می رود. به علاوه، این تحقیق ثابت کرد که پیچیدگی زبان بیانگر ساخت دانش در بحث های آن لاین است. کارهای متفاوتی می تواند صورت بگیرد تا پیچیدگی زبان در بحث های آن لاین افزایش یابد برای مثال: دادن تکلیف های خواندنی و نوشتنی به شرکت کنندگان. اندازه ی گروه ها نیز باید محدود شده تا از خستگی و کم کاری دانش آموزان در بحث های آن لاین جلوگیری شود.

Learning a foreign language is a challenging process in which learners need motivation and encouragement through the use of modern techniques. The present paper investigates the effects digital stories may have on Iranian pre-intermediate EFL learners’ listening comprehension. To this end, the researchers carried out a quasi-experimental research in a language institution in Tabriz (Iran). In total, forty, 11-14-year-old female students participated in this research. Twenty students were in the experimental group and twenty in the control group. The Preliminary English Test (PET) was administered at the beginning of the study to check whether all participants were homogeneous in terms of English language proficiency. A pre-test of listening comprehension was designed to gather initial data on the learners' listening skill prior to the treatment. The experimental group was presented with digital stories in a technology-equipped classroom. After the treatment, a post-test was administered to both groups to test the learners' progression in listening comprehension. Then, using an ANCOVA test, the performance of two groups was compared.The findings indicated that the experimental group outperformed the control group in the final test. The results raise interesting issues related to the use of technology in the context of foreign language learning, substantiating the link between technology rich environment and improved language learning.

This article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of English as a foreign language (EFL). The study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was affected and to investigate possible overlaps between EFL learners’ perceptions of task difficulty and hypothesized task complexity. A purposive sample of 54 first-year EFL learners randomly assigned to two parallel conversation classes in an English department of a major public university participated in the study and performed listening tasks in a language lab. The instruments used for data collection were seven tasks taken from a TOEFL Test Preparation Kit, each followed by listening comprehension questions and an item on the participants’ personal perception of the difficulty of the task. During counter-balanced administrations, the tasks were manipulated for one of the four dimensions of task difficulty (adequacy, immediacy, perspective, and prior knowledge). The resulting data included the participants’ perception of difficulty as well as their performance scores under less complex and more complex conditions. One-sample T-test and correlation analyses of the data revealed that for all of the four complexity dimensions, the hypothesized less complex task condition led to better learner performance. The correlation between learner-assigned difficulty score for the task at hand and theoretical task complexity level was significant only for the immediacy dimension (r=-0.67, p<.05). The results offer support for task complexity frameworks, raise doubts about learners’ perceptions of tasks, and imply possibilities for task manipulation in language learning contexts.

A longitudinal study was planned, and a scale was suggested for assessing EFL learners’ oral presentations. The scale had three major evaluation components: `Preparation’, `Organization’, and `Presentation’. The students were informed about the rating scale against which their performances would be evaluated. Throughout the course each student had five performances on different occasions. The results of the study indicated that: (a) significant improvement was observed in the learners’ performances, (b) ANOVA results indicated that the five performances were significantly different, (c) there were high correlations between each paired performances, and (d) the rating scale was a reliable and consistent measure by means of which the instructor could assess the student’s speaking ability.

This study was particularly concentrating on TOEFL type (CBT vs. P&P) and computer anxiety as independent variables, and test takers' performance as the dependent variable. The two TOEFL types (Paper-and-Pencil and Computer-Based) were given to 40 participants using counter balancing. The interval between the two tests was two weeks. The reason behind choosing this interval and counter balancing was to prevent the practice effect. Three days after the test, the computer anxiety questionnaire was also taken by the same participants. The results showed a high correlation between the scores on the two versions of the test (P&P vs. CBT), also there was no significant difference between the performances of t, and finally, there was no significant interaction between test type (P & high-, low-, and mid-anxious candidates on the two versions of the tesP vs. CBT) and computer anxiety level (high- anxious, low-anxious, and mid-anxious).

This study investigated the comparative effect of teaching idiomatic expressions through practicing them in conversation and paragraph writing on intermediate EFL learners’ idiom learning. The participants were sorted out of a population of 134 intermediate students in Zabansara Language School in Khorramabad based on their scores on a Preliminary English Test (PET) and an idiom test piloted in advance. The selected 84 participants were divided randomly into three groups: two experimental groups, namely, conversation and paragraph writing groups, and one control group. The two experimental groups received different treatments. In one class, idioms were taught and learners were asked to make a conversation practicing the new idioms, and in the other class, they were asked to write short paragraphs using the idioms. In the third class, the control group, the new idioms were presented and then practiced through different written exercises. At the end of the treatment period, the researchers administered an idiom posttest. The analysis of the collected data revealed that using new idioms in conversation and paragraph writing helped students learn idioms more efficiently than just practicing them through different written exercises. Moreover, the use of idioms in conversation proved to be more effective than using them in paragraph writing. The findings can have implications in preparing materials, teaching/learning foreign languages, and designing syllabus.

As an integrative component of textual structure, formulaic expressions (FEs) play a key role in communicating the message and comprehending the text. Furthermore, interlingually contrastive features of FEs add to their both significance and complexity of their instruction. Given these facts, this study was an attempt to explore a sound mechanism on how to teach FEs; whether an explicit or CA-based approach to FEs instruction could entail various achievements among EFL learners’ reading ability. To this end, three groups of Iranian EFL learners, identified as homogeneous based on Nelson Proficiency Test, were classified into one control and two experimental (i.e. explicit and CA-based instruction) ones. They were exposed to conventional, explicit and CA-based instructions of a set of selected FEs developed into and presented in the form of an instructional handout. Their Knowledge of reading was also tested based on a researcher-made diagnostic test prior to the experiment. Both quantitative and qualitative paradigms were employed to measure both the achievements and the extent of contrast between Persian and English languages in terms of FEs. The former analysis revealed significance difference among the groups in terms of instruction type effectiveness; both explicit and CA-based instruction groups outperformed the control group; on the contrary, no statistically significant difference was revealed between the experimental groups. Additionally, the latter paradigm revealed differences and mismatches between Persian and English FEs in terms of semantic, syntactic and pragmatic parameters. The findings could be insightful for EFL instructors, learners, textbook writers, and syllabus designers to take into account issues like these in their pedagogical programs.
