If I were to teach a subject it would be physical education. So my use for technology wouldn't be the same as to a science instructor. I would probably use about 10-20 percent technology in my physical education class. Reasons why I would integrate some technology into my curriculum would be to post quizzes about different sports I've taught, different links that my students could look up the rules, history of sports and to post grades online my students can always check anytime to see what their grade is.
