The purpose of these plans, developed by biology teachers, social studies teachers, and high school students, are: 1) to develop a systematic method of becoming informed on issues not solely based within traditional disciplines; 2) to provide students with an opportunity to help determine the direction and content of their studies; 3) to aid in expanding the traditional view of learning as a classroom activity; and, 4) to redefine teaching-learning roles to allow individual goal setting, self evaluation, and use of community resources. An introduction sets out the general context of ecological study, the assumptions on which the unit is based, and the general purpose of the course. The unit is lab and problem centered, and is built around an issue of the individual student's selection. The course is structured into two separate phases, the second one optional but highly desirable. Possible objectives of the course are listed, the framework of the course is discussed, and several pages show the suggested organizational frameworks in chart form. They include: an interdisciplinary course; a unit within biology or social studies; an interdisciplinary unit taught in both biology and social studies courses. Some ideas are discussed for differentiating between an area of environmental concern and specific envrionmental problems. (JLB)
