Thanks for the reply, Leslie.
I would do whatever worked to give the students the information I was tasked to pass on. No way word-of-mouth takes the place of experience of course, but sometimes I read people's comments on teaching and feel perhaps people view education as some sort of gauntlet that should be run, and the more difficult, the better. To do it right, the participant should be battered within an inch of his or her life.
No way your professors should ever just hand you the answers- the questions, perhaps, if you are going to have to write an essay summing up what you have learned in the course (for instance), but generally that should not be done. But, as we know, there are bad teachers...
