Reading volume is an important consideration for teachers wanting to improve literacy outcomes for students. The authors begin by reviewing evidence for reading volume and the ways in which reading volume can be changed. They identify four factors--access, choice, classroom discussions of texts, and book talks--that composed an intervention designed to increase reading volume. The authors identified 44 teachers in grades 1, 3, and 5 to implement the reading volume program and monitored the impact and implementation with classroom observations and teacher interviews. The impact was generally positive, with teachers describing changes in reading volume, motivation, writing achievement, and other factors.
