With this
perspective, the preparation of science and mathematics
teachers should be directed at guiding the
development of their knowledge and thinking in a
manner that considers the development of an
overarching conception of teaching with technology.
Preservice teachers must be challenged to
reconsider their subject matter content and the
impact of technology on the development of that
subject itself as well as on teaching and learning
that subject. But this attention must recognize the
importance that learning to teach is a ‘‘constructive
and iterative’’ process where they must
interpret ‘‘events on the basis of existing knowledge,
beliefs, and dispositions’’
