Designed to be used by practicing teachers, students who are learning to become teachers, and faculty members who instruct such students, this manual describes an instructional manipulation for teaching children with mild disabilities that increases opportunities for learning through the addition of extra information. The technique described uses teacher feedback to students' responses to supply students with additional information. The manual includes: (a) background and description of instructive feedback; (b) description of the nine steps involved in planning and using instructive feedback; (c) two case studies describing the use of instructive feedback in a sixth grade class and in a preschool class; (d) summary statements of the research on which the manual is based; and (e) a self-test to allow readers to determine whether they have acquired the content in the manual. An appendix includes a list of the studies that used instructive feedback. Charts listing the decisions to be made prior to implementing the technique, describing direct teaching strategies, and listing target behavior and related extra information are also included.
