the present meta-analysis was conducted to provide a quantitative measure of the overall effects of task complexity on chinese efl learners’ language production. based on the strict inclusion criteria, 12 primary studies were synthesized according to key features. eleven of them were meta-analyzed to investigate effects of raising the resource-directing task complexity. results revealed that ...

recently tasks, as the basic units of syllabi, and the cognitive complexity, as the criterion for sequencing them, have caught many second language researchers’ attention. this study sought to explore the effect of utilizing the cognitively simple and complex tasks on high- and low-proficient efl iranian writers’ linguistic performance, i.e., fluency, accuracy, lexical complexity, and structura...

evaluative and comparative analysis among educational projects remains an issue for administration, program directors, instructors, and educational institutes. this study reports a fuzzy complexity model for educational projects, which has two primary aspects (technical aspects and transparency aspects). these aspects may not be measured precisely due to uncertain situations. therefore, a fuzzy...

this study examined the effects of task complexity on written narrative production under different task complexity conditions by efl learners at different proficiency levels. task complexity was manipulated along robinson’s (2001b) proposed task complexity dimension of here-and-now (simple) vs. there-and-then (complex) in. accordingly, three specific measures of the written narratives were targ...

this research is intended to investigate educational change in complexity paradigm. complexity paradigm provide a new perspective for thinkers to changing the world and it's phenomena and many of theorists present new viewpoints in variant scientific domains according to the main components of this paradigm. for this, the researcher first investigates and criticizes educational change theories ...
