Some students learn better when visuals are used. Others may learn better through listening. And some need to have hands-on projects to do well.
All students differ, therefore there has to be a variety of teaching methods.
They should also be taught good ethics and morals. Lessons should include a correlation to the real world. Everything a student learns should be an objective relating to the curriculum, which is there to prepare a student for the college or working field. Students can learn from the teacher, but also from their peers. Group work is essential, because it helps the student learn to work with others.
