Schools committed to the success of all children must have an array of activities designed to enable learning by addressing barriers to learning. An enabling component for schools encompasses six areas of program activity. This unit, "Introduction to Classroom Focused Enabling as a Key Element in Addressing Barriers to Student Learning," is the first of a set of three dealing with classroom-focused enabling, the first activity area of the enabling component. All three units require a minimum of 7 hours of group time; this introductory unit is designed as a 2-hour session. The unit is an introduction to classroom-focused enabling as a key element in helping address barriers to student learning. The second and third units, outlined in this introduction, are "Managing Classrooms through Support, Guidance, Accommodations, and Appropriate and Essential Limit Setting" (2 hours) and "Teaching in a Personalized Way" (3 hours). Material included in this instructor's guide to the concept of the enabling component in the classroom includes: (1) an overview of the three units; (2) sample assignments to prepare participants for the first session; (3) session guidelines for the instructor; (4) a sample handout for follow-up and preparation for the second session; (5) samples of group guidelines for preparation and participation; and (6) materials for a follow-up packet for participants that include some written summaries and enrichment readings.
