Interactive visualizations and instruction in mathematics and physics. We can do so much more than what is usually presented for online learning. For example a catalog of visualizations, http://www.vizitsolutions.com/portfolio/catalog/ http://www.vizitsolutions.com/portfolio/catalog/, and a more complete lesson experiment http://www.vizitsolutions.com/portfolio/gausslaw/ http://www.vizitsolutions.com/portfolio/gausslaw/. The goal is for the student to interact with, to play with, the models. Of course almost all of this is open sourced :) The visualizations can even be easily embedded in any online content with just a few lines of HTML provided in the catalog.
