Built on a case-study approach to reading diagnosis, this classroom-based resource features strong research, a theoretical foundation and a developmental, constructivist perspective of literacy. In this fourth edition, the authors offer an Instructional Approach that consistently helps the reflective practitioner connect diagnosis with instructional planning. It provides many more cases from actual students and classrooms than other diagnosis books, as well as a strong research and theoretical grounding for practice. The authors introduce readers to early literacy screening, running records, informal reading inventories, miscue analysis, assessment issues related to national and state initiatives and much more.
