When students read silently they might be making mistakes without realizing it. Mistakes become harder to correct the longer they go unnoticed. Students benefit from hearing proper fluent reading. Also, when students read aloud they can hear their own mistakes and adults can hear where they might be struggling. This enables emerging readers to get the support and corrections they need. The importance of fluency and comprehension as distinct skills that are critical for academic outcomes and the role of immediate feedback is well-researched. (See the National Reading Panel).
