Does the Education System has a Huge role to play in Broadening One's Thinking & Perception?

The education system has to be one whereby the intrinsic motivations of the student isn't replaced by external motivations. But that is precisely where it is lacking, and one cant avoid this. Even something as piddling as class participation gets slapped with a reward, a certain component of one's grade devoted solely to how actively the individual contributes to the learning environment in the classroom. Students speak up simply to get a higher class participation grade and not because they are intrinsically motivated to do so... ie. genuinely interested to discuss on the issues raised
