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  comple...

The aim of the present study was to investigate the effects of two types of paragraph on EFL learners’ written production. It addressed the issue of how three aspects of language production (i.e. complexity, accuracy, and fluency) vary among two types of paragraphs (i.e. paragraphs of chronology and cause-effect) written by EFL learners. Thirty intermediate level learners of English participate...

We discuss several complexity measures for Boolean functions: certiicate complexity, sensitivity , block sensitivity, and the degree of a representing or approximating polynomial. We survey the relations and biggest gaps known between these measures, and show how they give bounds for the decision tree complexity of Boolean functions on deterministic, randomized, and quantum computers.

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...
