That is a hard question for me to answer.
The first class i signed up for was for hand piecing.I had already done some sewing when I signed up for that class. I think the instructor did a good job. I did learn a lot.
How much knowledge/ experience does the student have?
The only thing I can think of would have been statements that there may be more than one way to do something and sometimes patterns have errors. But at that stage, I doubt if I would have been able to tell there was an error.
But as a beginning beginner, I can only absorb so much information at a time and prefer to have only one fairly efficient method presented at a time.
Also, only so much information can be conveyed in a given time frame.
It seems like many of us were "imprinted" with whatever we first learned.
