Chapter titles include: Stages of Development, providing an overview of the basics of the reading process and how one moves from nonreader to reader status; Diagnosis, discussing proven techniques and instruments used to assess reading levels; Teaching Procedures--Stage 1, discussing teaching methods for each stage of the reading process; Stage 2--Reading to Learn, exploring a variety of ways students learn through their reading; Specialized Reading Skills, discussing reading experiences drawn from current study or related work materials through the systematic teaching of work study skills; and, Classroom Management, emphasizing individualized reading and instruction. A bibliography of 52 titles is presented and specimen copies of informal measures for assessing basic reading skills, including the Fry Readability Formula, and a reference list of instructional materials are appended.
