make class more conducive to learning

One suggestions to make class more conducive to learning.How can a system be designed so students care more for learning?

One way to make classes more conductive to learning can be by probably changing the grading system. Lets say you do all your homework and you tried very hard on it but then the next day when your checking it at school you get most of them wrong and end up getting an F. That really pisses a lot of people off because if you did your homework and ended up getting an F then you basically just waisted your time. Also the school can let us students have a little more hands on ativities, i enjoy that and im sure a lot of other students do too, and its not like we dont learn, i find myself learning a little more than ususal with projects.
