I have a small victory to share. The next day after my frustration about not doing the assignment in class, we (the class and I) talked about the situation. There response was, "Well, you told us if we understood that we didn't need to do the assignment". I almost jumped up and down! We then continued to talk about how we know that we understand it and a different student said, "Why don't you give us one of those quiz thingies." Meaning a formative assessment. I was exploding inside. They are figuring it out!!! Now, we are taking the summative assessment tomorrow, we'll see how it goes. If the indicators are right, we'll do well.
