That's the caveat here, and I believe it's referred to as intrinsic and extrinsic motivation (intrinsic means from within and extrinsic from outside).You can teach until your brain rots but if the student doesn't want to learn it's all for nil.
In a nutshell, the intrinsically motivated student is there because he/she wants to learn and get along/succeed and the extrinsically motivated student is there because mum and dad have sent him and say he/she has to get a degree (however worthless) of some type...but if he/she had his/her way would float along/sponge/feel entitled throughout life. They are both easy to spot.
Unfortunately, at many mainstream places the later is all too common.
