This is Allison Littlejohn's presentation on Collective Learning, described in terms of her research of the use of this in an international company (with colleagues).
This was not a topic that I initially had much interest in, but the MOOC has really thrown light on something I would not otherwise had considered.
The model that Littlejohn describes (see previous post Tools for Collective Learning) shows that this is a discipline in development and she provides a credible model of how it can be explained.
She describes "charting" as a sense-making process that allows people to make sense of the collective knowledge. [Google Swirl is one suggestion as to how to make sense of the collective knowledge - could not find this... now discontinued by Google]
Learning Goals help glue the whole thing together and give direction.
