The present study sets out to examine whether and how task structure affects the number and type of vague expressions used by a group of higher intermediate EFL learners. The participants were 50 Iranian EFL learners from 6 intact classes, all native speakers of Persian with limited opportunity to communicate with native speakers of English, and…

This study investigated the relationship between critical thinking and the writing ability of Iranian EFL learners, and the interrelationship among the subskills of the two constructs. Furthermore, it aimed at finding which skills of critical thinking predicted the participants' writing ability. To this end, 104 students majoring in English…

The study investigated the relationship among critical thinking, strategy use and university achievement. To this end, 76 English major students sat the California Critical Thinking Skills Test and filled out Oxford's Strategy Inventory for Language Learning. Participants' Grade Point Averages were regarded as their university achievement. The…

This study investigates the relative effectiveness of four types of input-enhanced instruction on the development of Iranian EFL learners' production of pragmatically appropriate and grammatically accurate suggestions. Over a 16-week course, input delivered through video clips was enhanced differently in four intact classes: (1) metapragmatic…

Based on a prior study by Chen and Truscott, the present study investigated the possible effects of repetition (repeated exposure) and L1 lexicalization on the incidental acquisition and retention of 10 English target words by 90 Persian-speaking EFL learners at an Iranian university. Seven aspects of vocabulary knowledge were measured, including…

This study was designed to investigate the effects of incidental unfocused prompts and recasts on improving English as a foreign language (EFL) learners' grammatical accuracy as measured in students' oral interviews and the Test of English as a Foreign Language (TOEFL) grammar test. The design of the study was quasi-experimental with pre-tests,…

The present study examines Iranian language learners' views on different types of oral corrective feedback and explores the relationship with learners' language proficiency. It then compares the learners' views with those of their teachers. The study is based on a 36-item questionnaire completed by 154 English as a foreign language (EFL) learners…

This study investigates the combined effects of task-based careful online planning and the storyline structure of a task on second language performance (complexity, accuracy and fluency). Sixty intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline…

To date, research results suggest that task repetition positively affects oral task performance. However, researchers have not yet shown the extension of the benefits of repeating the same task to performance of a new task. This article first provides an overview of the currently available research findings on task repetition and then presents the…

This article reports on a study which investigated the effects of correction of learners' grammatical errors on acquisition. Specifically, it compared the effects of timing of correction (immediate versus delayed correction) and manner of correction (explicit versus implicit correction). It also investigated the relative effects of correction of…
