Distribute the handout at the end of the session. You want your attendees to pay attention to the trainer. Ask for feedback, and listen to it. Be sure to ask for feedback. And be sure to take suggestions for improvement to heart.
Reruns are popular.
Repeat topics in subsequent sessions if needed, where you review the content of the earlier session. But also add new examples to build the attendees' skill level. Add a little variety. Occasionally offer a seminar with 30 quick tips in 30 minutes. In that session, build in a little more time to address questions.
