She stared at me with such confusion that I was actually taken aback. "But how can you assess us properly if you do not give us an exam that has fight or wrong answers?" she asked. I tried to explain my method of teaching to this sophomore university student, stating my belief that students being able to orally express their opinions, ideas and reason-ing is just as valuable as knowing a fight or wrong answer, that the "why" is just as important as the "what."However, during my explanation, I kept wondering if I was simply confusing her even more. She was so concerned. So serious. If I do not give the class an exam that has fight or wrong answers, then how can I possibly grade them fairly? If everyone has different opinions, then how can we know who is the best?
