Studies have shown that there is a direct relationship between homework and achievement. Effective school research indicates that those schools that assign homework and evaluate it in some manner are more successful at demonstrating better achievement by students. Through other studies, it has been found that those students who spend more hours on homework score higher on achievement tests. Perhaps William Raspberry was right when he indicated that students must work harder if they are to be successful.
Everything that students need to know cannot be learned within the confines of the classroom. This is why homework is an essential part of the total educational process.
