Hi Kevin: Practice is extremely important. Too often, teachers tend to cover material once or twice, then depend on the student to do remaining study on their own. It would be an unusual person to hear or see something once only and be expected to remember all the details. As an analogy, a concert musician must practice every day. Atheletes must practice every day. I think higher achievers include lots of practice in their quest for mastery. So, it should and can work the same way for students in school. Lots of opportunities for practice. And this would be best delivered by a variety of media choices. So when it comes time to assess or evaluate, there are no surprises becasue, execpt for critical thinking kind of questions or situations, the student has rehearsed sufficiently to exceed and succeed.
