I have found that when you plan really well for a topic, you find that you actually have more material than you need. The "say-do-watch" approach works in my environment, where the instructor says/lectures "briefly" about a topic, then does/demonstrates it so that students can see how it works, then watches the students duplicate the demonstration to satisfy the kinethetic part of the learning process. This not only takes up time, but also allows the students to quickly realize what they have learned. Using this approach to lesson planning can help with lessening instructor anxiety.
