When starting up the first day of class, I like to make sure we discuss important information like the syllabus, expectations, instructor access.
I also really like to see that students get to share a bit about themselves. We may talk about what their expectations of the class are...what do they think they will learn?
I also will bring in little treats to use as "prizes" for questions I will ask throughout the first night, just to confirm that they are absorbing the material. The "quiz" questions will include things on the syllabus, how to reach me and I may incorporate a few funny items to help make them comfortable. For example, when we introduce ourselves, I may ask them to tell us their name and the program of study and their favorite color. One of my quiz questions may be about the information we learned in our introductions or our conversation through the evening. I want them to feel that it is important to listen to each other and to ensure that they feel that they are active contributors to the class.
