The TED video of the Director of Disney's Imagineering indirectly relates to Education. It takes off after the "Candle Problem" is played out. This is a must see video that WILL CHANGE YOUR LIFE.
IMHO the dumbing down of education is actually the realignment of topics for simple grading systems. It may be that the increased use of multiple-choice tests drives away the type of problems that really matter. Furthermore, the debates about group work and, perhaps, the Math Wars, were and are distorted by inappropriate, simply false, evaluation methods.
