The Effect of Task Complexity and Recast on Iranian Intermediate Learners’ Speaking Accuracy and Fluency

This study attempted to look into the effect of increasing task complexity and the provision of recast in separate experiments on the EFL learners’ oral language production and their fluency and accuracy. For both experiments, oral narrative tasks were used (Heaton, 1975), adjusted in terms of complexity according to Robinson’s Triadic Framework along the +/ reasoning and the +/ few elements dimensions. For the effect of recasts, learners were provided with recasts when performing their oral narrative tasks. The obtained data were subject to repeated measures ANOVA and oneway ANOVA to provide answers to the research questions. Increasing the complexity of the oral narrative tasks led to high accuracy but low fluency, supporting Robinson’s (2011) prediction of the opposite resulting effects of raising task complexity on fluency in L2 production. The provision of recasts, on the other hand, influenced learners’ accuracy and fluency in their oral productions positively by implicitly focusing their attention on the form of their communication. And, comparatively, recasts and task complexity did not differ in terms of their contribution to oral accuracy and fluency, approving their special benefits for each dimension of oral production in isolation. Results are discussed in light of Robinson’s Cognition Hypothesis.Keywords: task complexity; corrective feedback; recast; oral production; accuracy; fluency
