I may seems like a daunting task, but it only takes a minute. I have different students accompany me to take the trash out each day after food production, and during that time I might ask where they are from, what interests them and what their goals might be. I try to keep it informal, and not like an inquisition. I try to make a mental note of it so I can get an update later, or revisit the conversation a month or two later when they are no longer in my class. Students see that you care....because you do!
