By multimedia we mean both new-technology, multisense, virtual-object
teaching tools (internet files, multimedia encyclopedia, subject
paths and multimedia text books [1]) as well as non-virtual, colorful
and easy-to-find objects, like Physics toys [2]. Grouping Physics
objects into thematics, like:
- non-conservation laws (Celtic stone – rattleback,
springing balls, self-inverting tippe-top [3])
- electricity sources
(Volta piles from moneys, light-emitting diodes used as photovoltaic
cells,Helmholtz coils turning in Earth’s magnetic field,
piezoelectric lighters)
- optics of sky light (CD used as spectrometers, CD covers
used as Brewster polarization analyzer, plastic pieces used
as polaryzers) one stimulates students of pedagogical faculties (and
not
only) for
searching on their own easy and cheap teaching tools.
A second step
is then preparing virtual paths with these thematics, where the
same in-vivo presentation becomes a virtual path, as a video-tape or
interactive
internet or CD-path. In particular, the advantage of the CD-path
is that it allows more than one time performing the same experiment
or showing conceptually easy, but difficult to repeat in the
same way, experiments, like the fall of levitron [4]. [1] U.Amaldi, Fisica
