Lesson Plan Design... Backwards?

Something that really stuck out to me this week was the way one of our articles in particular says is the best way to design a lesson. In my mind, and how I've written the few lesson plans in my past, was to start from the beginning and write it from start to finish. In a sort of chronological order kind of way.This idea is flawed. It describes writing a plan in a backwards kind of manner. It suggests identifying your ideal results first. Makes sense, that is the point of teaching. Next it suggests how you will assess your students in achieving those results. It's important to figure out how you want to "test" them. Lastly, it suggests actually writing out the activities and instructions. In this manner, you can be certain your lecture and activities will lead to your desired goal.
