I heard my school district will modernize and replace the classic "blackboard" (or greenboard) with modern 'whiteboards'. I can't help but wonder if this is a dumb idea.
AFAIK, blackboards last forever. Lots of old schools still have their original ones. In contrast, whiteboards seem sensitve to nicks and scrapes.
I believe black/greenboards cost less than whiteboards.
But most significantly is the chalk vs. marker.
Chalk is much cheaper than markers. Markers always run out quickly. Someone forgets and uses the wrong kind permanently staining the whiteboard.
Lastly, markers have that weird chemical smell.
Seems to me there's nothing wrong with blackboards and nothing to be gained by whiteboards.
Thoughts anyone?
