This module is the third section of a four-part how-to manual for integrating curriculum in grades K-12, especially in Missouri. The module outlines step-by-step procedures for integrated units, integrated years, and integrated schools. Comments from teachers, students, and administrators who are actively involved in integration in Missouri schools are interspersed throughout the module. The schools from which ideas were drawn were selected to represent a broad spectrum of learning environments, from urban to rural, from magnet school to comprehensive K-12. The module is organized in four sections explaining how to implement four types of integration: (1) developing integrated units of study; (2) the integration of elementary schools; (3) integrating academic and vocational education; and (4) integrating the entire school district. The module also includes descriptions of 10 school reform measures, a glossary defining 19 terms, and interspersed lists containing 8 references. (KC)
