Purpose: This study aimed to examine the effect of gradual self-control of task difficulty and feedback on accuracy and movement pattern of the golf putting sport skill. Method: Sixty students were quasi-randomly assigned to four groups under a varying combination of the two factors of task difficulty control (self-controlled or yoked) and…

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 impacts of task characteristics on second language (L2) writing require further exploration. This study examined the effects of increasing task complexity on L2 argumentative writing. Upper-intermediate L2 learners performed two writing tasks with varying degrees of complexity in relation to the number of elements and the degree of reasoning.…

An Oral Proficiency Interview (OPI) may be evaluated either during the interview procedure (direct-method) or from a tape-made oral interaction (semi-direct method). Such variety in methods of assessment can influence test takers' scores extensively. However, it is not conclusive whether such differences are due to test format or something else.…

This study investigates the direct and/or indirect effects of some cognitive (working memory capacity) and affective (writing anxiety and writing self-efficacy) variables on the complexity, accuracy, and fluency (CAF) of second language (L2) learners' writings. To achieve this goal, 232 upper-intermediate English learners performed an automated…

Second Language learners' oral task performance has been one of interesting and research generating areas of investigations in the field of second language acquisition specially, task-based language teaching and learning. The main purpose of the present study is to investigate the effect of focus on form and task complexity on L2 learners' oral…

Task-based planning can be conceptualized as the opportunity to work out task performance before the actual performance. It allows learners to process the content and language of their planned production at a deeper and more meaningful level. In the face of the wide range of research conducted on the effects of pre-task planning on L2 production,…

This study was carried out to find out if there was any significant difference in learning English collocations by learning with different dominant experiential learning styles. Seventy-five participants took part in the study in which they were taught a series of English collocations. The entry knowledge of the participants with regard to…

This main purpose of this paper is to investigate the impact of task complexity on L2 learners' written narratives. It is argued that L2 learners' written performance is influenced by the complexity of task regarding accuracy, fluency, and complexity. 52 Iranian English learners were selected as the participants of the study. They were asked to…

It is argued that tasks with different structures yield different performances in terms of accuracy, fluency and complexity. The present study is thus an attempt to investigate the impact of task structure on second language task performance. Thirty two upper-intermediate Iranian learners of English performed two narrative tasks (Structured vs.…
