I believe apps are extremely helpful in teaching. In physical education I believe that apps can speed up the learning process for many students. I think that a lot of students learn better when they can see themselves doing something wrong and then explain to them how to change it. An app like Coach's Eye can do exactly that. If I am teaching a weight lifting class and trying to teach a technique to a lift, I can record a student's attempt and then show the student exactly what they are doing wrong and how to fix it. This is just one example of a useful app. There are many other apps out there just to make a teacher's life easier like apps to take roll, make teams, organize brackets, and countless others. I think as a coach and teacher I will find what works best for me and use apps to better enhance the learning of the students.
