Fortunately, that changed. At some point, I decided to speak less. Now I demonstrate, making sure everyone is watching only me, not doing anything with me. Then I sit down, (that is important), and sit back, close my mouth, relax my tongue, and do absolutely nothing but watch my students, each and every one of them. Then, I say the one thing they need to hear next, stay on point, answer a question succinctly if asked. I demonstrate once again, having everyone watch, in silence. I sit back down, lean back, and watch again. And so on.
