The two ideas are contrary. One learns by doing, by being involved, by having an action result in a reaction. MTV, and TV in general, may spoil many things but children are born with a quest for knowledge. Through careful application of brain-numbing hoopla this quest is often killed before the child reaches second grade. It is also parent's fault who plop their kid in front of a TV just to get some peace and quite for themselves for a while.
TV is a lousy baby-sitter.
And it's also parent's fault for losing interest themselves. Like parent, like child. The sins of the parent are always vested on the child when the parent does the vesting. I'm not a teacher, and I'm not advocating replacing teachers with computers or robots. But good students usually find out that even good teachers don't know all that much about a subject and bad teachers know even less.
