What is the Future of Teaching?

Until recently, online learning has mainly been of the expository sort, essentially a traditional lecture format adapted for the web. But newer, social and multimedia technologies are allowing online tools to evolve to offer more active and interactive lessons. No longer is online learning just reading a module and answering questions — it can now include synchronous or asynchronous discussions and peer-to-peer learning exercises. As a result, online learning is becoming a more useful tool as both a replacement for and enhancement to traditional face-to-face learning.
