This is what I love to see in my classes: students helping and instructing their classmates.
In Graphic Publications, a graduate from the class of 2017 returned for a week to help the new editors settle in. It was great to have Sam in class working with the yearbook editors, Lauren and Grace while I worked on lessons with all the new students.
Im my Costume & Fashion Design class, I had 2 students who joined class after the first, so they needed to do a little catch up. Classmates taught them the skills they needed (separating thread & threading a needle) to catch up on the assignments.
