Hi Shereene: You're, right, students really enjoy the field trip and or guest speaker experience. Facination about the the students future career seems to to capture their attention and may motivate them to study harder afterwards based on the activity. Another factor is many students have only vague ideas about the work setting. Also, as they visualize themselves in these settings as graduates, they can be inspired. Genaerally, classes ought to schedule more speakers and field trips, because they are a unique and memorable experience. Regards, Barry
