The IMS machine readable notation system – part of IMS LD – could be the basis of a notation system for instructional design which allows us to talk about instruction. We would need to have it become human readable before it would actually be useful in teaching ID. This kept reminding me of a session on notation systems by Andy Gibbons and Sandy Waters given here last year.
According to David Wiley it will take a lot of work before it could serve that function.
