I'm teaching my daughter how to cycle. Or rather: trying to because there is not much progress, even though we cycle almost every day. I suspect she is not very motivated to learn it now as she keeps on going in weird direction whereas I believe she can keep the cycle straight (if only she wanted to :) and then I get angry which doesn't help. My other daughter learned it very quickly so that's another lesson that the teacher cannot take full credit for a rapid learning process.
But it made me reflect on the cycling skill as a very visible one and hence easy to explain what you learned: I learned how to cycle. This in contrast with what I have learned over the past year about blogging for instance. While cleaning my folders, I found a discussion I had with Beth Kanter not even a year ago, on blogging, when she stimulated me to start one during the online facilitation workshop where we met. During the year I learned a lot, not only about how to post and how to install a sitemeter, but also about the blogosphere, blogging 'cultures' (whenever you can provide a link, do so) and a lot of things which are even harder to express, like fiddling with the tools made me more audacious with other online tools, or like not being embarrassed. And sometimes I talk to someone about a topic I blogged about, and maybe able to articulate my thoughts much more clearly. At time I feel the same while working with a younger colleague. It is then, that I realize how much I have acquired/changed over time.
So why am I saying this? Partly to be able to show this nice picture (some of my postideas start with my visualisation of a picture) but also because I notice so often that it is hard to talk about knowledge and know what people can contribute, or articulate what you or your organisation can bring to the process. It is in the contrast with other people (working or talking with them) or with yourself in the past, that this may become more visible.
