The present study compared the effects of reading input flooding and listening input flooding techniques on the accuracy and complexity of Iranian EFL learners' speaking skill. Participants were 66 homogeneous intermediate EFL learners who were randomly divided into three groups of 22: Reading input flooding group, listening input flooding group, and control group. The reading flooded input group was exposed to the numerous examples of the target structures through reading. In the same phase, the listening group was given relatively the same task, through listening. The participants' monologues in the posttest were separately recorded, and later transcribed and coded in terms of accuracy and complexity through Bygate's (2001) standard coding system. The results of ANCOVA indicated the outperformance of reading input flooding group. The study also supported the trade-off effects (Skehan, 1998(Skehan, , 2009) between accuracy and complexity.Key words: accuracy, complexity, listening input flooding, reading input flooding, speaking skill
Introduction
Input enhancement (and input flooding as one of its versions) is SharwoodSmith's (1993) expression for referring to any pedagogical technique that teachers use to make specific features in the input more salient because noticing the input facilitates its learning (Schmidt, 1990). However, the findings in the domain of input enhancement are controversial. While some studies emphasize the usefulness of input enhancement and input flooding techniques (Ellis, 2003;Izumi, 2002;Jourdenais, Ota, Stauffer, Boyson, & Daughty, 1995;Lee, 2007;Rashtchi & Gharanli, 2010;Shook, 1999;Simard, 2009) others minimize their efficacy (Alanen, 1995;Leow, Egi, Nuevo, & Tsai, 2003;Overstreet, 1998;Radwan, 2005;Wong, 2003).Input flooding is an implicit technique of focusing on form in the dichotomy of implicit and explicit activities that attempt to attract students' attention.
