What was even cooler was that the educator could assign different problems to different groups and send one groups‘s answer to another,to see if they agreed.Even better,a smart feed provided the educator with instant feedback,which enabled him/her to assist tudents that were struggling with a concept,while allowing the rest of the group to continue going ahead.And,what if the entire class was struggling?He/She couldsimply post it on the whiteboard and explain it to them at the same time.Though the study was used largely for math,the desks could easily be used to teach other subjects as well.
