In today's world, many students in the U.S. schools aren't taught to work hard. The complain about the homework load; or they complain that the teacher wasn't clear and they can't do the homework. They don't think to figure it out themselves. In fact, schools today are worried that the students are too stressed and make adjustments. There is a trend to dumb down the curriculum so that everyone can "succeed." Schools are looking to eliminate laning or tracking of students.
