While alot of this unit's content was familiar, it was supported by good research and was a great reminder of some important steps for getting students to remember content. The suggestion to reinforce content through review (what's been covered) and preview (anticipate what's to come) was familiar and, I thought, apt. In public speaking, we say "preview, view, review" for your audience - that look back and look forward allows students to download previous content, reboot their attention spans and prepare for new material. I particularly appreciated the concrete tidbits of research - eg, 2-4 topics in 30 minutes - that offer practical "on the ground" reminders for improving student success.
