emilio balzano:
Teachers adopt innovation contributions only in very special situations, because experimentations leave less room for the development of the usual curriculum, which is well inserted in the overall system
I was until recently professor of Physics at Napoli University,
responsible for several national research projects about
teaching/learning of physics and mathematics, and now continuing in the
research commitments
Experience shows that it is important, in addressing to teachers, to
avoid mistakes already made several times with pupils: in order that
significant changes can be obtained, it is important that the
"asymptotic" goals of the proposed changes are modulated in structure
and time according to the actual (teaching) conditions one strives to
change. What has to be changed, in fact, are mostly quite profound
"ways to look at" different components of the teaching habit: cultural
structures, pupils' cognitive dynamics, cooperation with colleagues,
roles possibly played by technologies, classroom handling and
gestures, ... and so on. In order such aspects coherently produce an
effective impact on pupils, they must be gradually (re)appropriated by
teachers as driven to reciprocal resonance: in practice, this means a
gradual (guided) drift from the actually practiced teaching modes to
new, more satisfyng ones. As with pupils, this can be obtained by a
far-sighting, supporting "mediation": at resonance with an individual
and collective commitment to a change which should be actually seen and
experienced as possible, meaningful, relevant, rewarding ... the more as
the change itself proceeds in the proposed direction. Obviously
supporting technologies and curricular architectures are important, but
the crucial condition rests on the quality of a competent, and carefully
planned, "human" mediation.
