Having worked with struggling readers for many years, I have often referred and recommended Dr. Tim Rasinski’s work on fluency. He’s been my go-to researcher for all things fluency, from his books, The Fluent Reader, Increasing Fluency with High Frequency Word Phrases Grades 1-5, and Fluency through Practice and Performance, to his countless articles, a few of which can be found here, here and here. Much of his work has attributed to my students finding success in reading.
