ILTweb - Institute for Learning
Technologies webmaster@ilt.columbia.edu
In
the 21st century, information and knowledge will
arbitrate the fate of both individuals and
institutions, and, more than ever, an enlightened
citizenry will need to be intellectually
empowered to provide for the common good. New
communications technologies are facilitating once
hard to practice pedagogies -- learning by doing,
inquiry-based education, project methods,
autonomous study, in short, educators' great
humanistic hopes and unfulfilled progressive
aspirations. These have been the aspirations of
the enlightenment tradition and the Institute
believes that in the 21st century Teachers
College and Columbia University should and will
be at the vanguard of their historical
fulfillment. Towards this end, the Institute
seeks to advance four basic objectives:
Technology configuration
-- ILT seeks to configure advanced
technologies in everyday educational
settings, especially inner-city schools,
to support constructivist curricula and
pedagogies.
Curriculum innovation
-- ILT acts to promote the
reconfiguration of knowledge into an
integrated, comprehensive resource, open
to all, for bringing ideas and
understanding to bear in the conduct of
life.
Professional development
-- ILT works to help teachers adapt to a
setting in which students will exert
substantial control over their
educational work and have direct
electronic access to all the resources of
their culture and in which teachers will
exercise influence primarily by posing
powerful questions and by guiding student
inquiry towards the frontiers of
knowledge, understanding, and reflective
practice.
Policy formation --
ILT aims to sustain public policy
initiatives that rally broad coalitions
of interested parties from academe,
government and industry committed to
transforming education through the astute
use of information and communications
technologies.

The five
Platonic solids are the tetrahedron, the cube, the octahedron,
the dodecahedron, and the icosahedron. Their faces are regular
polygons. These solids are perfectly symmetrical in that each
face of a solid is identical to every other face of the solid,
each vertex is identical to every other vertex, and each edge
is identical to every other edge.
Each Platonic
solid has a dual: a solid whose vertices correspond to the
faces, and faces to the vertics. The dual of the cube is the
octahedron. The dual of the dodecahedron is the icosahedron.
The tetrahedron is its own dual.
There are 13
slightly less symmetrical solids called the Archimedean
solids. The faces of these solids are regular polygons,
their edges have the same length, and their vertices are
identical. Their faces, however, are not identical. An
Archimedean solid may have two or three different polygons as
faces.
