I am an instructor with students ranging from 18 to about 35, many of the techniques I use I get from my daughter who is a 3rd grade teacher. Students are students, many of the behaviors seen in 3rd grade shows up in my classroom. Students of all ages learn with repetition and all seem to enjoy games. We tweek games that are played by people on their phones, and turn them into dental related games. The students at times get very competitive abd they are becoming involved in the process.
