New technology in education is playing a big role in classes. One of the most affordable and effective is a simple video recorder. With the use of a video recorder students can see the mistakes they're making in things such as a throwing motion or swinging form.  Studies show that students find this more effective than having someone try to explain what they are doing wrong, and then trying to correct it.  Educators also found the use of other technologies such as pedometers and heart rate monitors very successful, using them to make step and heart rate goals for students.
