The Effects of Task Characteristics on L2 Learners’ Production of Complex, Accurate, and Fluent Oral Language

Mansoor Fahim, Saeed Nourzadeh, Jalil Fat’hi


One recent fruitful development in the area of second language (L2) acquisition has been Task-Based Language Teaching (TBLT). Consequently, L2 researchers have paid particular attention to the role that the employment of tasks plays in the development of interlanguage competence. Of particular interest have been the factors that increase the difficulty with which L2 learners perform and process pedagogical tasks. The present paper is an attempt to present a review of factors that have been found to affect learners’ task performance, along with studies that have provided empirical evidence as to how these factors increase the cognitive demands of learners’ task performance. Understanding the functioning of these task performance factors are of paramount importance to language teachers who are to follow TBLT principles since such understanding can provide them with sequencing criteria that can guide the order in which they employ tasks in their everyday teaching efforts.
