Fluent oral reading is essential for success in elementary school. In this study, we investigated the effectiveness of enhanced reading fluency instruction for struggling readers. The intervention was provided to small groups of students at risk for reading difficulties. Students were assessed on key early literacy skills. Second-grade students who were at risk for reading failure and who received supplemental intervention scored higher on measures of fluency than students who received only typical classroom instruction; the effects of enhanced fluency instruction were evident across different dosages for many children at risk for reading failure. In addition, statistically significant improvements and relationships were evident for oral reading fluency and comprehension. We discuss guidelines for developing and using the intervention in other classrooms. (Contains 3 figures and 4 tables.)
