This widely adopted text explores key theories and models that frame reading instruction and research. Readers learn why theory matters in designing and implementing high-quality instruction and research; how to critically evaluate the assumptions and beliefs that guide their own work; and what can be gained by looking at reading through multiple theoretical lenses. For each theoretical model, classroom applications are brought to life with engaging vignettes and teacher reflections. Research applications are discussed and illustrated with descriptions of exemplary studies. The table of contents includes the following: (1) Introduction to Theories and Models; (2) Early Roots: Early Theories and Models Applicable to Reading; (3) Behaviorism: The Dominant Educational Theory for 50 Years (1900-1950s); (4) Constructivism (1920s-Present); (5) Theories of Literacy Development (1930s-Present); (6) Social Learning Perspectives (1960s-Present); (7) Cognitive-Processing Perspectives; and (8) Putting It All Together.
