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...

this study investigated the impact of sequencing tasks from simple to complex along +/- reasoning demands on the fluency of writing task performance among efl learners. the participants of the study were 90 inter- mediate efl learners from three classes at islamic azad university, shahr-e-qods branch in iran. they were distributed in three groups: experimental a, experimental b, and a control g...

Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothes...

In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the...

This quasi-experimental study set out to examine the effect of peer corrective feedback on feedback givers and receivers in L2 writing. The forms in focus were a/an, the, and the past tense.The study was conducted in an EFL classroom setting with 45 learners of English in three writing classes which served as the feedback givers, receivers, and the control group.  Over four sessions of treatmen...

Based on Robinson’s Cognition Hypothesis, this study explored the effects of task complexity on the lexical complexity of Iranian EFL students’ argumentative writing.This study was designed to explore the manipulation of cognitive task complexity along +/-single task dimension (a resource dispersing dimension in Robinson’s triadic framework) on Iranian EFL learners’ production in term of lexica...
