"The first module in the LETRS series explores the reasons why many students have reading difficulties and explains how children learn to read. Case studies illustrate the progression of reading development; the influences of biological, genetic, cognitive, environmental, and instructional factors in learning to read; and the components of effective reading instruction. A "four-part processing system" model is explored in detail."--p. [4] of cover.

The book gives tips on how to teach reading and how a teacher can figure out how to help a student that needs intervention.
