Part I of this research summarizes the developmental phases ACOT teachers go through as they
gradually replace their traditional beliefs and practices with new ones (see ACOT Report # 8). The
report represents the teachers’ development as five phases: Entry, Adoption, Adaptation,
Appropriation, and Invention. In this model, the teachers’ traditional text-based curriculum is
delivered in a lecture-recitation-seatwork mode is first strengthened through the use of technology and
then gradually replaced by far more dynamic learning experiences for students.
