**Reflexion.**
===After this courses, my way to plan my class has changed. I remenber a day when Dr. Ourland said us, how to connect the real world with math,? and Dr. Lundin said us "think how to show different representations of topic to students." Those two senteces were in my mind. And one day, I did a class plan different than I did before. I realized that I had converted my traditional way of teaching in a motivating way to learn and teach. I feel satisfied with what I have learned.===
