Reading fluency is a critical component of reading proficiency in both the L1 and L2. It lays a foundation on which readers build their reading skills to become strategic and versatile in using a variety of cognitive and metacognitive strategies of reading. In this paper we propose Assisted Reading as a flexible method for developing reading fluency for L2 readers of varying levels of reading proficiency. Complementary to Extensive Reading, Assisted Reading provides L2 readers with powerful scaffolding which empowers them to increasingly read faster and comprehend better. First, we discuss why reading fluency is critical in L2 reading, then provide a brief overview of methods for developing reading fluency in L2, and finally suggest Assisted Reading as a flexible and promising approach for that purpose.
