Scribner and Cole observed that in schools, the primary information sharing tool, language, contrasts with the more natural observational learning to which humans are accustomed. People are hard-wired to be able to imitate something by just watching and mimicking someone's movements, something S and C called "observational learning."
In most schools today, a student's "information bandwidth" (my new term) remains untapped to its fullest potential. While schools are getting better at this (what with SMART Boards and PowerPoints) I believe there is still a ways to go.
All it takes is a little extra effort on everyone's part and teachers will be able to triple their students' information bandwitdth.
Visually (images, videos, games)
Kinesthetically (trips, activities)
Another option only requires a computer lab! Most of the world's museums have interactive tours and exhibits which put kids inside the exhibits themselves. Many smaller museums are happy to arrange guest speakers to visit and/or a guided virtual tour. See some links below I found after 15 minutes of research!!
