Teaching goal:
1) Quantum Mechanics is one of the difficult courses and much new knowledge compared with the traditional physics for the graduate students because they thought it is too unrealistic and abstract. So in order to bring their interesting on it and master the principle of QM after learning, I tried to do followings:
2) Let them ask questions on the class off the class as possible as they can. Encourage them to raise their questions and try to answer these questions as possible as I can. Let them feel free to ask any kind of question and encourage them do not postpone their questions so that they can follow the process of the class and do not save their question in their mind. By doing so, students can clear up stones and break through to the key concept of QM. Once they really understand what they have learnt they become interested in QM.
3) Base on the text book but bring deeper and wider knowledge referring other good QM books for them so that they can extend their knowledge of QM not only from reading the textbook but also from the class. In this way, they would feel like to attend the class and pay attention on the class, making notes and
4) Make a clear syllabus and also in each class, briefly review what have learnt in last class and make a link between the last class and the present class. In such summary, students will remind what they have learnt last class and bring an interesting and question for the present class. Therefore they will pay more attention on the class.
5) On the class not only teach the concept and topic but also talk about how the equations and conclusion come from by proving and driving in details. In such a way, students will have more clear understand what is the principle of QM, how the QM theory set up, also training them how to solve the QM problems using mathematical tools, physical principle and their background knowledge.
6) Assign homework and grade the homework for students so that they can accept what they learnt on the class and do more excises to solve the problems themselves. Also by grading their homework, I can get the feedback about more clear understand each student’s level and what is needed to improve. I also point out where they did wrong and what is the correct answer so that they known what they need to improve themselves.
