Hi Tracy:
Good thoughts, Tracy. Students often get very moved by the field trip experience. It may be that they realize that they will soon be actually working in that setting. Or, maybe the see the reality of holding down a job they're being trained for and the end of dood old school days.
But guest speakers and field trips can be quite inspiring, even motivate some students to try harder as they get invigorated to ready themselves for the profession they're being trained for. And as you point out, the ability to ask questions can really stimulate thoughtful visions of opportunity that many may not have considered.
Regards, Barry
