Multi-institutional teaching communities in computer education

In contrast, for most of us, our teaching lives are relatively private, and primarily confined to our own university. We tend not to read teaching literature, we are guided primarily by our direct experiences, intuitions, and introspections. The outcome is rarely exposed to peer review beyond our own institutions. Given these double lives, is it any wonder that, while Information Technology continues to leap forward as a consequence of research, the teaching of Information Technology remains, for the most part, the same-old-same-old? Could the down turn in student numbers be related to that same-old-same-old?
