This study was an attempt to investigate the effect of choice theory-based instruction on Iranian EFL learners' vocabulary achievement. To fulfil the purpose of this study, 60 female advanced EFL learners were selected from among a total number of 90 learners through their performance on a piloted sample Cambridge ESOL Certificate of Advanced…

The study reported in this article examined the impact of task type on the ways in which learners resolve grammatical language-related episodes (LREs) and whether the level of engagement affects subsequent language development. Data were collected over a six-week period. Thirty-two Iranian second language (L2) learners were paired up to complete a…

The current study investigates the effects of dynamic and non-dynamic oral corrective feedback in response to learners' errors on English as a foreign language (EFL) learners' English wh-question development over three treatment sessions. Sixty-eight EFL learners were assigned randomly to one of two experimental conditions that received either…

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 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…

This study explored the impact of listening strategy training conducted within two strategy interventions on pre-intermediate and intermediate EFL learners' comprehension of unidirectional listening. Participants were divided into two experimental groups (n = 156) and a comparison group (n = 50). Each experimental group was trained in eight…

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,…

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…
