B.f. Skinner said this quote
“ Why did colleges make their students take examinations, and why did they give grade? What did a grade really mean? When a student studied did he do anything more than read and think-- or was there something special which no one in Walden Two would know about? Why did the professors lecture to the students? Were the students never expected to do anything except answer questions? Was it true that students were made to read books they were not interested in? ”
