This quantitative study aimed to investigate the combined effects of two types of strategic planning, namely collaborative and teacher-led planning conditions and task complexity on Iranian intermediate language learners' oral production in terms of complexity, accuracy, and fluency. To achieve this purpose, 90 EFL learners were selected through convenience sampling from a language institute in Shiraz, Iran, and randomly assigned to two control and four experimental groups. The study adopted a quasi-experimental design in the form of pretest, treatment, and posttest. In the first step, all participants took part in a speaking pretest in which they were required to narrate a story based on a series of picture description tasks. While the experimental groups underwent 10 treatment sessions of picture description task performance along with two planning types i.e., teacher-led and collaborative planning conditions, the control groups were not allowed to plan the task performance. In the last session, the language learners took a posttest whose results were compared with those of the pretest. The findings revealed that the language learners in the collaborative planning groups outperformed the other groups in terms of both fluency and complexity. Further, teacher-led groups did better than the other groups in terms of accuracy. This study carries crucial implications for EFL teachers, material developers, syllabus designers, and speaking skill examiners.

The concept of demotivation and removing possible barriers of learning has been researched and advocated throughout the ESL/EFL literature but it seems that it has not been well studied at least on Iranian seminary EFL learners. As such, this study aimed at investigating the effect of demotivation on oral performance of Iranian EFL seminary learners and finding possible demotivating factors which may affect it. The participants were 50 male intermediate EFL learners studying at Islamic Propagation Office, Isfahan, Iran, selected based on their performance on the Oxford Placement test. A pretest-posttest design oral performance exam was used. The participants were divided into two groups of motivated and demotivated group based on the motivational questionnaire (Celce-Murcia, Brinton, & Goodwin, (1996). The collected data included: (1) the results of the motivational questionnaire, (2) the results of the oral tasks (used as pre and post tests) and (3) responses to a semi-structured interview regarding the possible demotivating factors which may influence participants' oral performance. The independent sample t-test and paired samples t-test were used to determine whether there were significant inter and intra-group differences. The results provide evidence that motivation helps enhance EFL seminary learners’ oral performance and demotivation significantly hinders improving it.

Reading is recognized as being the most important skill needed by ESP learners in their field of study, and vocabulary knowledge is the most widely discussed component of effective ESP reading per se. However, research on how much the different types of words exert substantial influences over ESP reading comprehension remains scanty. To address this lacuna, the present study aimed to examine the degree of contribution made by general high-frequency, core-academic, and technical-academic words to 127 Iranian learners studying Psychology at three state universities in Tehran, Iran. Three researcher-made and validated tests were used to measure the three aforementioned types of vocabulary knowledge accompanied by an ESP reading test. Data analysis using multiple regression revealed that the core-academic words and technical-academic words significantly contributed to the ESP reading comprehension, explaining about 92% of the variance in reading scores, but knowledge of general high-frequency words was not a significant contributor. Moreover, teaching core-academic and technical-academic words did not have a significant effect on ESP reading comprehension in the short term, yet a low significant difference was observed for technical academic words in the long term. Findings of this study imply that direct teaching of the core-academic and technical-academic words can help ESP learners improve their reading over time. The article ends with pedagogical implications and suggestions for future research.

The current comparative study aimed to juxtapose the newly compiled English textbook for the students in the third grade of senior high school, Vision 3, and the previously taught English textbook for pre-university students. To this end, 130 experienced teachers, with the experience of teaching both textbooks, were asked to complete an eclectic checklist comprising 38 items and evaluating the book in terms of nine major criteria, namely general considerations, vocabulary, grammar, speaking, listening, reading, writing, pronunciation supplementary materials, tasks, and activities. Following that, 20 teachers were interviewed to enrich the results of the quantitative data. Overall, the results revealed the teachers’ contentment with the newly developed English textbook. In particular, the mean values indicated that English teachers rated the speaking and listening sections as the most satisfactory parts while they ranked the supplementary materials criterion as the least satisfactory one in Vision 3. Indeed, they believed that notwithstanding the dramatically positive changes in Vision 3, the book still requires undergoing major revisions to act as a rich source for enabling the EFL students to communicate fluently, accurately, and effectively. In this regard, the findings would benefit the materials developers to locate the areas for further modifications.

Considering the paramount importance of writing logical arguments for college students, this study investigated the effect of dynamic assessment (DA) of Toulmin Model through teacher- and collective-scaffolding on argument structure and overall quality of argumentative essays of Iranian EFL university learners. In so doing, 45 male and female Iranian EFL learners taking part in the study were randomly assigned into three groups (two experimental groups including the teacher- and collective-scaffolding and one control group), each consisting of 15 learners. Toulmin Model of argumentation was used as an instructional tool in this research. The necessary data were collected through a pre- and post-test argumentative essay. During the experiment, the dynamic assessment groups wrote and revised their essays in response to teacher’s or peers’ supportive dialogue and zone of proximal development (ZPD) sensitive feedback on the argument structure of their essays; whereas, the control group did not receive such mediation and they were evaluated on their own independent performance. The results of statistical analyses carried out on post-test scores on argument structure and overall quality of the essays pointed out to the outperformance of the teacher- and collective-scaffolding groups on both variables. Furthermore, follow-up Post-hoc analyses revealed no significant difference between the teacher- and collective-scaffolding groups in terms of the overall quality of the argumentative essays. However, the statistically significant difference between the two experimental groups with regard to the argument structure indicated the outperformance of the teacher-scaffolding over the collective group. The obtained results support the fact that autonomy and improvement cannot be thrust upon learners, rather they need to be assisted wisely towards independence.
