In our modern technological world, Computer-Assisted Language learning (CALL) is a new realm towards learning a language in general, and learning L2 vocabulary in particular. It is assumed that the use of multimedia annotations promotes language learners’ vocabulary acquisition. Therefore, this study set out to investigate the effects of different multimedia annotations (still picture annotations, dynamic picture annotations, and written annotations) on L2 vocabulary learning. To fulfill this objective, the researchers selected sixty four EFL learners as the participants of this study. The participants were randomly assigned to one of the four groups: a control group that received no annotations and three experimental groups that received: still picture annotations, dynamic picture annotations, and written annotations. Each participant was required to take a pre-test. A vocabulary post- test was also designed and administered to the participants in order to assess the efficacy of each annotation. First for each group a paired t-test was conducted between their pre and post test scores in order to observe their improvement; then through an ANCOVA test the performance of four groups was compared. The results showed that using multimedia annotations resulted in a significant difference in the participants’ vocabulary learning. Based on the results of the present study, multimedia annotations are suggested as a vocabulary teaching strategy.

The purpose of the present study was to investigate the effect of context on learning idioms among 60 Iranian female advanced English learners. To this end, the researcher assigned the participants to two experimental groups and one control group: Group 1 (first experimental group, the extended-context group), Group 2 (second experimental group, the limited-context group) and Group 3 (control group or the decontextualized group). First a 50-item idiom test was constructed using Vocabulary Knowledge scale (adopted from Wesche and Paribakht, 1993) and answered by the participants. The results of this test revealed that thirty idioms were not at all familiar to the participants. So these 30 idioms were selected as the target idioms. Then, the researchers applied two types of treatment to the participants in groups 1 and 2. Group 1 was taught idioms in extended-context through listening to short stories including the target idioms, Group 2 in the limited-context through listening to single sentences including the target idioms, and Control group (Group 3) was taught idioms through their decontextualized definitions of the target idioms. The analysis of the results of immediate and delayed post-test showed that extended contexts had significant influence on the participants’ idiom learning and retention. Pedagogical implications are provided.

The present study aimed at investigating the effects of explicit and implicit recasts on Iranian EFL learners' acquisition of English relative clauses. For this purpose, 64 participants were selected out of 94 intermediate level EFL learners at Falagh language Institute, Rasht, Iran. To have homogenized groups, the researcher administered a language proficiency test (TOEFL). Then, the researchers assigned them randomly to the explicit recast group, implicit recast group, and control group. They carried out some information gap tasks within four sessions. One group received explicit recast, the other group received implicit recast and the control one got no corrective feedback, for the target linguistic errors during the task performance. A grammatical judgment test was applied as the pretest and immediate posttest. The results of a paired-samples t-test and analyses of variance (ANOVA) showed that the scores of all three groups improved significantly overtime. However, the explicit recast group did significantly better than both the control group and the implicit recast group. The results of the study were elaborated in terms of counterbalance hypothesis and noticing hypothesis. The superiority of explicit recast implied a beneficial role for negative evidence in SLA and that explicit recast was a better choice than implicit recast in the L2 classroom.

The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University. The first group was provided with form-focused interaction enhancement, the second with the meaning-focused interaction enhancement, and the third was the control group which received no interaction enhancement. During 12 sessions, the participants practiced using prepositions employing oral picture description and written picture description tasks. Having practiced using prepositions during the term using different tasks, the participants were presented with Oral Picture Description (OPD), and Written Picture Description (WPD) tasks in posttest. The results indicated that there are differences among the participants regarding their use of prepositions in performing oral picture description task in form and meaning–focused interaction enhancement- based classes. It also became clear that the group with meaning focused interaction enhancement outperformed the group with form- focused interactionenhancement and the control group. There were also differences among the participants of the three groups regarding their use of prepositions in WPD task in form and meaning -focused interaction enhancement- based classes.

Different methods of language teaching have tried to help EFL learners to develop good language skills based on their various perspectives. Research findings have underscored the effect of using task types in promoting language skills in terms of accuracy in written discourse. Therefore, this study set out to investigate whether there is an evidence of correct use of simple past tense (Accuracy) based on Task Complexity (Task type :Here-and now & There-and-then),Task Conditions (Gender: Male & Female), and Task Difficulty (Proficiency: Lower-intermediate & Intermediate). Sixty Iranian English learners in a language institute participated in the study and were assigned to four groups of lower-intermediate male, lower-intermediate female, intermediate male and intermediate female. Initial homogeneity of the groups was verified using two general proficiency tests; KET for lower-intermediate and PET for intermediate. All groups in here-and-now task type were asked to write a story using simple past based on a picture strip while for there-and-then task type the participants were supposed to write about their last birthday. The results from paired samples t-test, independent samples t-test and two-way ANOVA analysis of the written data revealed significant differences in performing task types, at different proficiency levels and interaction between them. The findings have significant pedagogical implications for EFL learners to understand the relationship among Task Complexity,Task Conditions, Task Difficulty and L2 written production leading to various degrees of Accuracy.
