Is it okay for my students to chose where they sit in the morning or do I need to have an assigned seating chart? Most of the time there are no behavior problems in the class.
I do not see the need for a forced seating arrangement if there are no behavioral issues. The only issue I may see is that perhaps a student has eyesight or hearing issues and may need to reserve a front seat. If they don't already prioritize the front seat, simply asking for anyone who needs special accomodations to come up, and have a soft reserved seating system should be more than adequate.
