While I am on the subject, what is especially difficult in science
education reform is that new instructional materials often address
multiple innovations, such as cooperative learning, new approaches to
assessment, inquiry teaching, new definitions of content, new
structure and sequencing of content, and so forth. This is what the
CBAM researchers call an Innovation Bundle. Implementing an
Innovation Bundle has the potential of increasing the complexity of
the change dramatically. However, it also has the promise of pushing
over the critical excitation state the need to enact significant
changes (such as to culture, views of learning and teaching, goals,
and methods) rather than accepting superficial changes (such as block
scheduling or minimum time requirements for laboratory teaching).
