Jay Cross has made an extensive posting in his Informal Learning blog about informal learning. It really captures all the important points about informal learning that you need to know. Here’s a clip:
"People acquire the skills they use at work informally – talking, observing others, trial-and-error, and simply working with people in the know. Formal training and workshops account for only 10% to 20% of what people learn at work. Most corporations over-invest in formal training while leaving the more natural, simple ways we learn to chance."
However, if you want to know more, then you will need to wait for his Informal Learning book due out in November 2006.
