This booklet describes the work of the City College Advisory Service to Open Corridors, a New York City public school program committed to changing schools in ways that will better support children's own spontaneous patterns of learning. In part 1 of the booklet, the advisors describe how they proceeded to educate themselves for the advisory role they undertook, and how they worked with teachers, children, administration, parents, and the community. The facts and figures of the advisors' efforts in a single district are reported in part 2. The information for this part was taken from the memos and logs submitted to the Director of the Advisory Service. In part 3 the spread of Open Corridors' philosophy and expertise through former advisors who have gone to new assignments is described. Finally, the future of the advisory role is discussed in part 4. (RC)
