"...they've rather taken on a language of their own which bears a resemblance to English but isn't quite."Do learning outcomes have any value? Like all aspects of education fossilized by officialdom, no.
Except that, in each of the MOOCs I have experimented with over the past few months, I have been careful to set my own learning outcomes at the beginning, and to measure my achievement against these, rather than any externally-imposed criteria set by someone else. So learning outcomes do have value - we've just got them the wrong way round.
