As a teacher who has her students do homework, I do see a need for it. The homework should link to the classroom or a skill and it should be simple and easy for students to access. When students get to secondary school they are inundated with homework. If we do not at least introduce them to a some expectation or doing work outside of school hours then we are setting them up for failure before we begin.
Take a look at this video about homework and tell me your thoughts.
