I recently came back from maternity leave. I wanted to find out what my students had retained while I was gone. When I have returned from being gone, students always love to tell stories about what happened. Some say they learned everything, and some say they didn’t learn anything. Instead of doing this, I gave pairs of students whiteboards and quizzed them on concepts. They did well, and I could easily tell what I needed to review. I let them work in pairs to take the pressure off of each student. I always make students rotate the boards as well. I assured them that if they did not remember something that we would review it later. It was such an easy task… I was surprised it took me so long to figure it out!
