Some presenters had basic lectures with PowerPoints, some provided “think-pair-share” opportunities for participants, some had laptops for participants and guided us through simulations or software tools (an advantage to sitting up front), and others had the participants actually do the hands-on activities. Most had handouts, although I was glad to see that many had just a basic one-pager outline and then gave us the URL of their website to download a variety of resources—less to carry and a lot greener!
