Pictures save the day!
The first step to building professional relationships of respect with students is to know and use their name. I have problems remembering the names of some of my students that are in my hybrid classes, since we only meet once per week. The Great Southwest Teaching Conference in October is an annual conferenced for sharing out of good teaching ideas. A colleague I met there confessed to the same dilemma, and shared their solution - a picture of each student at the beginning of the semester!
