The current report, Part II, puts a magnifying glass to the five-phase model and examines the
individual development of two ACOT teachers. These personal examples illustrate the conflict and
vacillation ACOT teachers experience when teaching and learning begin to change in their highaccess-
to-technology classrooms. The critically different outcomes of the two teachers’ experiences
demonstrate the need for support from both colleagues and administrators that is appropriate at each
of the five phases.
Research shows that instructional change is not a matter of abandoning beliefs, but of gradually
replacing them with more relevant beliefs developed through experiences in a supportive environment
(e.g., Nespor, 1987). If there is no change in the larger system, the struggling teacher and the innovation
are doomed to frustration or abandonment (Bowers, 1973; Schiffer, 1979). The current research
demonstrates that implementation of significant change efforts must take into account the need to
recognize teachers’ belief systems and to design appropriate support.
