2/4 Protein purification, guest lecture, 25min.

2/10, Feedback from Zachary;

1) difference between my class and those he considered as excellent: control over questions. e.g. I ask a question, and a student gives me a wrong answer. How do I lead him/walk him towards the right answer rather than just giving a right answer? 

2) lots of times, I asked a question, no one answers, I will imediately give them the answer. 

Sometimes, it's because they don't understand the questions. So it's better for me, to repharase the question; ask again; or pause for 30sec. 

3) add pause for students to catch up; (in the fomat like activiteis; asking questions and wait long)

4) design questions based on Bxx taxonomy: know/understand/apply/analyze;

Zachary: my questions are all in the same level; ask advanced questions!

5)train students by waiting: if no one answers, just wait, to let them know someome got answer.

6) activity: some advanced questions; let students pair and discuss for one minute; then volunteer.

7)my accent: he said he can understand 95%, because the pace is good: not too slow; not too fast. also because the engagement; and my concistency.

8) video: too long. usually 2-3min is great.

9) chocolate thing: very good.
