"Nothing's really new Sam." This was a statement made to me when I mentioned that I remember attempting to negotiate the curriculum in the 1980's after Garth Boomer's book 'Negotiating the Curriculum' was published.
Boomer's approach was essentially inquiry learning - issue or problem, question, hypothesis, test, and conclusion. Negotiating the curriculum adopted four questions:
1 What do we know already?
2 What do we want and need to find out
3 How will we go about finding out?
4 How will we know, and show, that we've found out when we have finished?
Pretty straight forward really and it stands the test of time.
