Only one third of the interviewees noted any organizational or operational reasons for implementing a STW curriculum at their site. Interdisciplinary teaming was most often cited as the organizational reason for implementing the STW curriculum at the middle school level. The teaming concept allowed for greater infusion of career materials and information across the different teaching areas. A director of vocational and technical education viewed teaming as "a way to expand options and reduce departmentalism." A suburban school principal saw the STW curriculum as a "method for redesigning instruction and learning environments to include practices such as interdisciplinary teaming that encourage career infusion and integration by teachers." Some sites referred to the career cluster organizations and block scheduling at area high schools as reasons for organizing their curriculum in a similar or complementary fashion. Others felt the STW curriculum supported the nature of a small school or school-within-a-school (academy) structure. Block scheduling is discussed further in the section titled "Implementation Issues and Concerns."
