The recording of lectures for students to revisit after a contact session is becoming more and more prevalent. This is especially relevant in South Africa where we have eleven official languages. Many of your students may not speak English as their first language and may struggle with understanding the language, never mind the concept you are trying to get across.
You probably already know that we already have a pretty amazing collaboration tool at the NMMU. Blogs, forums, wikis, shared documents, online calendars to name some of the functionality. SharePoint 2010 is indeed very powerful. Both our student and staff portals as well as their mobile versions run on custom developed SharePoint 2010 sites.
