The rationale, objectives, descriptions, evaluations, and plans for an alternative junior high school, Markles Flats which is a joint collaboration of the Ithaca public system and the Human Affairs Program of Cornell University, are described in this paper. As part of a broader effort to develop a different educational environment for a group of students, and for the higher education institutions in Ithaca to contribute skills and resources to the community, the school aims to foster the individual development of its 85 pupils, each in relation to his fellow beings, namely, a school whose classroom is the community and the world. During the first year Markles Flats was in operation a strong leadership was lacking, some students were drifting and unruly, and community interaction was somewhat neglected. Although pupils progressed academically at the same rate as students in other Ithaca junior high schools, on the positive side, the Markles Flats students evaluated their school higher, and a parents' organization was started. Planning for the second year worked to eliminate problems of the first year, implementing a more structured system with strong leadership. Appendices include sections on student goals, evaluation, student body, selection of teaching assistants, and plans for the continuation of Markles Flats School. (SJM)
