Web-quests are internet-based technology applications in which groups of students follow a specific set of steps toward the completion of a final project on a specific subject or a multi-disciplinary subject. The present study aimed to investigate the impacts of using web-quests on learning vocabulary by Iranian pre-university students. The sample of the study consisted of 72 students assigned into two groups. One of the groups represented the control group, and included 23 students; the other group represented the experimental group and comprised 49 students. The two groups were chosen from a population of pre-university students in Chadegan, Isfahan, Iran. The web-quest strategy was used in teaching the experimental group, while the traditional method was used with the control group in the second term of the school year 2015-2016. An Oxford Placement Test (OPT), a vocabulary pretest, a vocabulary posttest, and an attitude questionnaire were the data elicitation tools employed in this study. The collected data were analyzed using independent-samples t test, which was used to determine the existence of possible significant differences between the groups both before and after the instruction. The results indicated that there were statistically significant differences between both groups in favor of the experimental group. The conclusion, thus, could be that the students in the experimental group, who used the web-quest resources for learning vocabulary, performed significantly better than the students in the control group, who learnt vocabulary through traditional method of learning vocabulary. Finally, questionnaire data analyzed via one-sample t test indicated that the experimental group learners had a positive attitude towards the treatment they experienced in the experiment.

The present study is an attempt to compare the use of different forms of greeting speech acts presented in Iranian junior high school textbooks, i.e. Prospect series (I, II, III) and Four Corners series (1, 2, 3 and 4) which are quite popular in Iranian high schools and institutions. To this end, greeting forms in the language function and conversation sections of these two series were analyzed to see how they were presented on the basis of a modified version of Searle’s (1967) greeting speech act classification introduced by Hang (2010). The obtained results indicated that ‘greeting by using questions’ was the most frequent form of all greeting forms in both series. In addition, the results of chi-square revealed that there was no significant difference between the occurrence frequencies of greeting forms of speech act in the two series. The findings of the study have some implications for textbook designers in terms of incorporation of speech acts in upcoming textbooks.

The present study investigated the potential role of tasks in engaging Iranian EFL learners in task-supported language learning, affecting on learner-centered instruction and the correspondence between the objectives and contents in current pre-university English course book (Learning to Read English for Pre-University Students). To do this, 100 Iranian EFL teachers of pre-university grade were invited to participate in this study. They were asked to fill out a 5-point Likert scale checklist (adapted from Lawrence, 2011). The checklist was initially piloted on 20 EFL teachers in order to see to what extent the items were clear and comprehensible to the subjects of the study and to find out the internal consistency or reliability of the items. The results of statistical analyses indicated that teachers tended to agree on the point that tasks have significant capability in engaging learners in communicative language use or task-based language learning. The vast majority of the teachers expressed that using tasks in textbook can improve learner-centered instruction. The evaluation of the textbook showed the contents are corresponded to their objectives.

Drawing on the assumptions of socio-cognitive linguistics, focusing on the effective role of interaction in terms of reducing the cognitive burden in the process of learning, this quasi-experimental study aimed at investigating the effect of the Interactive Whiteboard (IWB) usage on the learning and retention of non-congruent collocations among 60 homogenized Iranian EFL learners, aged 18 to 24 years old. To this end, the sample selection procedure yielded two intact groups: the experimental group (N=30) who experienced learning collocations through the IWB and the control group (N=30) who learned them through the use of conventional board. The t-test results of the comparison between the two groups on both the immediate and delayed post-tests indicate that the experimental group outperformed the control group, suggesting the effectiveness of the IWB for the purpose of learning (Sig. value = 0.01; Eta squared = 0.10) and retention (Sig. value = 0.04; Eta squared = 0.06) of non-congruent collocations, thus providing support for the interactive function of instructional materials, such as IWB. The procedure and promising findings may provide insights for considering the integration of IWB into Iranian EFL learning settings.
