This accessible text provides an extensive survey of the major theories and models that influence reading instruction and research. Readers learn why theory matters in designing and implementing high-quality instruction; how to critically evaluate the assumptions and beliefs that guide their own work with students; and the benefits of approaching everyday teaching situations from multiple theoretical perspectives. Every chapter features classroom application activities and illuminating teaching vignettes. Of particular utility to graduate students, the book also addresses research applications, including descriptions of exemplary studies informed by each theoretical model.
