What are some of the key signs of trouble brewing in a modern student? Could they be withdrawn for a reason? I find that experience counts here, not just in teaching, in people. Pulling from your own experience has always been a good way or drawing from a close friends trails and tribulation. Human first, teacher second is always a good way to teach but never as easy as it sounds. I try to take a step back and view from an outside perception. Look for things like quite, not smiling during good times, excessive phone use, sleepiness or lack of energy. These may be signs of trouble for this young person, but could also be signs of a hard worker. Feel free to ask “small talk” type questions, feel free to get to know your students, you may learn something and even help a few along the way.
