Clarence suggests walls are thinning: "Using the tools we have, we have learned a few things about venturing outside of those walls ourselves and bringing the world in. We have learned to make connections on demand, on schedule, and as needed. We connect with others and forge stronger connections between ourselves...But to prevent them from becoming isolationist and insular, they also need to have thin walls in their learning environments."
I agree. We need permeable learning spaces so that we can reach out to the broader world, to have experts, communities, and networks of teachers (rather than only the one standing in front). And we need permeable learning spaces so we are able to check our own conceptions against those held by a broad community. Insular activity (whether thoughts in our heads or conversations with like-minded people) are deceptive. We can begin to think that we have touched truth and wisdom, when in reality, we have only touched similarity.
