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 int...

This study aimed to investigate the impact of task sequencing, along +/- reasoning demands dimension, on writing task performance in terms of accuracy.  The study was motivated by Robinson’s Cognition Hypothesis (CH) as well as previous studies investigating the relationships between task complexity and second language production. The participants of the study were 90 intermediate students at t...

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...

This study investigated the effect of sequencing tasks from simple to complex along +/- reasoning demands on fluency in writing task performance of English as Foreign Language (EFL) learners. The participants of this study included 90 intermediate EFL learners from three intact class divisions at the Islamic Azad Uni- versity, Shahr-e-Qods Branch. They were distributed in three groups: Experime...

Abstract This study investigated the validity of processability theory proposed by Pienemann (1998/2015) among Iranian EFL learners’ oral performance. The theory defines six procedural stages for learners in the process of second language acquisition. In order to conduct the study, 10 intermediate EFL learners were selected based on their performance on Oxford Placement Test. Then, they partici...
