This future education keynote by Bill Nye has very reasonable predictions for the classrooms of the future. Instead of bringing up far out ideas which include robot servants, Bill Nye predicts better synergy and collaboration methods as a result of access to already available technology.
Bill Nye proposes that instead of having text books, students will have tablets that will have access to all human information as a result of the Internet. They will use the tablets in order to gain valuable research, which will work in collaboration with hands-on learning right in the classroom.
As explained in Bill's future education keynote, this methodology will lead to breakthroughs in human intelligence.
