Breck: Placing OER (open educational resources) online without optimizing their components to signal is like expecting a single cell or group of cells to perform their role in isolation. Quite right. How would this work? "There are other very effective signal methods inherent in learning resources including: experts linking to (creating a network with) other OER they respect, landing pages that point (signal toward) excellent OER, and RSS-type signals that roll out expertise as it is published." Or to put the same points more concisely: 'stand-alone' learning objects need ways of connecting to the wider environment.
