These curriculum pieces, developed by teachers involved in the New York and the World Program, vary from single lessons to full units and indicate new approaches that all teachers can use in determining what to teach and how to teach it. The first section provides an overview of an interdisciplinary model along with steps in the process. The next section illustrates a two week interdisciplinary unit on perception that includes lessons in social studies, English, and art. The third section, "A Latin American Unit: Forest Hills High School" (Mark Kaufman, RoseAnne Coons), focuses on Colombia. The fourth section, "Japanese Aesthetics: High School of Telecommunications" (Philip Weinberg, Kathleen Nilsen), consists of activities to lead students through a visual experience of Japan and the United States. The fifth section, "Africa/Latin America - English Lessons: Port Richmond High School" (Janet Schoor), offers lessons to be used in conjunction with appropriate social studies lessons or as ideas for co-planning between the English and social studies teachers. The sixth section, "'Enrichment' Ideas: Townsend Harris High School" (Lynne Greenfield, Debbie Michlewitz, Judy Biener), provides lessons to enrich humanities offerings. The sixth section, "Interdisciplinary Art: Richmond Hill High School" (Leslie Marti-Munoz), delineates four projects adaptable to different organizing centers and different regional areas of study. A final section describes other projects conceived and developed by teachers in the program. (CK)
