The research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing.

Look up your professor's political and ideological affiliations on his/her Twitter and Facebook accounts, parrot their stance in your classroom comments and written assignments, and sit back and enjoy your "A".
