The purpose of this study was to explore the practices of formal and informal teacher technologists in two school settings: an elite private, high school academy and an urban poor, middle school academy. This investigation included clarifying the role of the formal and informal teacher technologist and investigating the need for both formal and informal teacher technologists. This study also explored the technological differences between the public academy middle school and the private academy high school. Two formal and eight informal teacher technologists were interviewed face-to-face three times, each using the transcendental phenomenology research design. Each teacher technologist was also observed at least once in classroom and teacher training sessions. The results of this study revealed (1) the role of the teacher technologist was a fast technology problem solver; and (2) although students and teachers used technology, the schools lagged in adequate technology and/or teacher training; (3) the teacher technologists used the Internet to build and evaluate curriculum; (4) most students used tool software centered around project-based activities; (5) teacher technologists trained other teachers to be collaborative risk-takers in using technology; (6) teacher technologists shared what they learn with students and other teachers; and (7) students could be student-learners or student-teachers and teachers could be teacher-learners. Four conclusions were reached: technology and constructivist teaching are compatible; technology is a tool; new approaches to professional development are needed; and hardware and software should be standardized for maximum use. Additionally, both schools in this study were evolving the role of the formal teacher technologist. It was recommended that (1) the schools employ at least one fulltime formal teacher technologist whose main role is to assist teachers in technology classroom incorporation, (2) the schools form teams of informal teacher technologists, (3) and the public middle school academy purchase one laptop for each student to use anytime, anywhere.
