V. NEW TOOLS AND OLD
The spinning globe
The planet earth spinning on its axis in geography class
is still attractive. Cheap plastic ones are now used, which
can be passed from hand to hand. We remember our planisphere
hanging on the wall, but today innovations in cartography
include digitized maps and satellite photographs that can
reach a computer screen in an instant. Some day we will have
holographic or virtual reality images of our planet. If we
add to this the incorporation of false colors for purposes
of agricultural, industrial or ecological surveys one can
get an idea of the substantial change that has taken place
in the mental representation of our planet. All this is now
possible for a computer linked to a network. This new
dynamic vision represents a considerable enrichment in the
forming of "planetary awareness" from the primary school
stage itself.
