Did the Stone age end when we ran out of stone? Maybe not, but in looking at the pace of change in our education system, we may need to ban chalk! Think about it, each of 'The Three Ages' (Stone Age; the Bronze Age; the Iron age) were each represented by materials. In education, our history in tools: The Slate and Chalk Age (mid 1800's - present) The Paper and Pen Era (1900's to present) and the Internet and Keyboard Period (2000's to present) But we're still tied to both chalk/chalkboards; and paper/pen as tools! School 2.0 may one day arrive, harnessing the power of global networking with today's multimedia tools... But we may first have to "Ban Chalk!" (with paper and pens to follow shortly thereafter) in order to get educators to use the tools of the present!
