Edward, I would try two approaches. One, provide the students with "guided notes" where the key concepts are listed and the students fill in the supporting information as you go through it. This way they can see what is important and will have written down the supportive content and this helps with cognitive retention. The second thing I would do is to give them problems to solve using the just delivered content. Then discuss their results. This will help them to see the application of the content because in many cases they are really sure what questions to ask about the new content because they are still internalizing it. Hope these strategies are helpful to you. If you have more questions please let me know. Gary Dr. Gary Meers
