In this presentation, three approaches for involving teachers in curriculum planning are described, including the interdisciplinary team approach, the total district approach, and the total faculty approach. Each of these approaches is illustrated with "snapshot" descriptions of promising practices from Colorado, Arizona, and Illinois. Projects described are 1) a Colorado Department of Education program to teach teachers how to plan interdisciplinary units of instruction; 2) a districtwide project in the Amphitheater District of Tucson, Arizona, to implement an innovative approach for accommodating a variety of learning styles; and 3) a project in Urbana, Illinois, in which a total faculty participated in reorganizing an elementary school in order to personalize learning and improve the pupils' achievement. The Colorado concept of accountability, described as a "school improvement process," is briefly contrasted with approaches in other states. The Colorado process stresses priority setting and teacher involvement in planning processes. (Author)
