PaperDesk is an app that allows you to take notes and use your iPad as a whiteboard. Connect your iPad to your projector with a VGA output and share your notes with everyone or present information to a group. You can also record your presentation and then email it, export it, print it, or place in your google docs. The app has a lite version if you want to preview before you buy, but the full version is worth the $2.99.
People will remember more if you space out some of the learning. You can provide little follow-up sessions to the course where they get refresher content. I once designed a course for project managers. After the elearning course, we sent out a series of planned emails.
We can send out timed emails to teachers after a session. Use gmail and tasks. Compose a draft email. Go to the "Draft" folder and check the box next to the email you plan on sending out. Go up to "More actions". On the dropdown menue, choose "Add to Tasks". Then you can save that task to a specific date. Of course, you need to check on your google tasks or set an alarm for that task. The point is you can plan and send emails. Cool!
