Four schools with technology rich environments were studied to gain a better understanding of the impact of technology infusion in schools. The four schools selected were a rural high school, a suburban middle school, an urban elementary school, and an urban high school. Cross case analysis shows certain characteristics these schools shared. All were characterized by adaptability and the ability to change to suit the circumstances. Each of these schools had a vision of how the technology would be used. In all cases the principal and the media center coordinator were important to maintaining the momentum of the implementation. Planning efforts were diverse, and ranged from the top-down strategy of one school to the bottom-up planning of another. In one school, the small size of the school allowed technology implementation to proceed informally. Several barriers to innovation had to be overcome in these schools, but planning made it possible to overcome staff and community resistance. Implementation of educational technology must be seen as a journey and not an event. (SLD)
