B, may cause students to care less about learning
Alfie Kohn is an American author who specializes in the area of education. He advocates progressive education and he puts into question many of the tradition approaches to learning.
According to Kohn, homework for students has mainly negative effect on them. It provokes the loss of interest in learning because it is something forced on them, to be accomplished during their free time. Children become frustrated and exhausted, resent school and learn even less.
There is no proven evidence that homework benefits academic benefits of students.
