While most of our classrooms were built under the assumption
that information is scarce and hard to find, nearly the entire body
of human knowledge now flows through and around these rooms in one
form or another, ready to be accessed by laptops, cellphones, and
iPods. Classrooms built to re-enforce the top-down authoritative
knowledge of the teacher are now enveloped by a cloud of ubiquitous
digital information where knowledge is made, not found, and authority
is continuously negotiated through discussion and participation.
