10. Unique Learning Methods
Communication, communication, and communication!
Listening?
Recording everything?
Self-learning?
Self-check, asking, listening, practicing, making correction immediately
Don’t be quite
“I already know” so I did not respond to you (team member or instructor), e.g., class information
You will not be charged or lose points by asking questions.
No question is called stupid question.
Real detailed question, not just for leaving impression.

11. These questions are welcome!
Detailed technique issue
Can I work out this with you together?
Detailed process or procedure
I forget what is discussed in class about …, can you explain it again (not the entire thing)?
Concern for improving class teaching and learning
I think …
Please do not ask any of following questions.
What is the answer you are looking for?
How can I / What must I do to get an ‘A’?
