I liked the idea of the dots on the students' watches. The red dot means to get instructor oversight, with the other dots reminding the students of other steps. I teach Radiology for the Dental Hygienist, and there are times they need to have the instructor come and check their first two images. That could be our red dot. There is always the lead vest, which at times gets forgotten. There could be a dot for that. A very subtle way of remembering and having the instructor know where they are in their appointment.
