I decided to adopt this method in my own way. Throughout my room I have four small posters of the Mona Lisa with colored arrows pointing to her. On the first day of class, we talked about what to do when I say "Mona Lisa".
- Eyes on the Speaker
- Mouth closed (no talking)
- Hands to yourself
- And smiling (optional)
Once I told students about it, I had them practice by me saying "Mona Lisa". Some students gave me a pretty darn good impression of the Mona Lisa. I told students that when I say this, it means I have something very important to say that they shouldn't miss. Throughout the semester I have to remind them every now and then on what this means and why it is important but it is a unique way to get their attention without straining my voice or yelling "Quiet down!".
