This worktext applies current theory to classroom practice by providing, in each chapter, a brief explanation of major concepts followed by guided practical experience in administering, scoring, and interpreting reading assessment techniques. Like the popular previous editions, the Fourth Edition: *emphasizes the use of assessment and diagnosis for instructional decision making--rather than for simply giving grades; *stresses the use of informal assessment techniques--reflecting the current emphasis in educational assessment theories--but also includes coverage of standardized test scores; *provides both classroom-tested results and interpretations of the data, giving students step-by-step experience in administering, scoring, and interpreting assessment techniques; and *includes numerous "hands-on" activities.
