Maureen,
I'm sorry you feel this way, I admit this course is more about delivering effective presentations in a meeting format rather than classroom instruction.
Based on my experience I have the following to be fairly effective. First of all, I would try to get the students involved as much as possible, including getting them up & moving around. If you are lecturing, break it up with periodic paired discussions. Ask a couple of thought-provoking questions that they really have to think about that pertain to what you just said. Then have them get up & find someone in a different part of the room & give them 2 minutes to discuss, that's 1 minute per person. Hold them to the 2 minutes & then, while they are still standing, ask a couple of groups to share what they discussed. Then have them sit by their "new friend." Repeat this every 10-12 minutes. I have found that this keeps the class on it's toes & also is a great way to check for understanding. Hope this helps.
