This usually means, however, that young people learn to see the knowledge the teacher wishes to convey as a way to get the reward, rather than something interesting to pursue for its own sake. They do not view it as something useful in its own right, so they do not question or evaluate what they are learning. Once the prize has been achieved, young people no longer have any motivation to retain what they have learned. Extrinsic motivation therefore, does not promote deeper or meta-level learning.
