A: SOMETHING KNOWN: ====== The OECD is - as most Math-teach participants would probably be aware - the "Organization of Economic Co-operation and Development" - a grouping of (currently) over 30 nations for the purposes of, yes indeed, "economic co-operation and development" (exactly as suggested by its name). They claim to be working to develop "Better Policies for Better Lives" (evidently of the citizens of OECD nations) - see, for instance: http://www.oecd.org/general/listofoecdmembercountries-ratificationoftheconventionontheoecd.htm .
B: SOMETHING THAT MAY NOT BE KNOWN: ====== Readers here may not be aware that the OECD has set up a "Centre for Educational Research & Innovation" (CERI) for the purposes of, yes indeed, "research and innovation into education" and educational issues in general - as is suggested by the name of the Centre. CERI does extensive research work which covers learning at all ages, from birth to old age, going way beyond the formal education system. (See, for instance, http://www.oecd.org/edu/ceri/ ). Judging from all I've been reading about it, CERI does seem to have done much valuable research into education (including math education).
CERI has published a major work titled "The Nature of Learning". I have not read the book as the cost is way beyond what my budget will bear. However, I have read several parts of it - and here is a link to a PDF file that describes it pretty well: http://www.oecd.org/edu/ceri/50300814.pdf
We note that practically all of the work of the CERI is in full agreement with what develops from the OPMS approach. It may be useful to observe the OPMS goes rather further, in many dimensions, than do the CERI research and practice documents. In view of this, Robert Hansen may be willing to forgive the undersigned for not having taken ANY of the 'valuable' advice he has often tendered without being asked.
Here below a listing of the main chapters of "The Nature of Learning" (It is particularly interesting to observe that "Inquiry Based Learning" [Ch. 9] is a prominent feature of what is recommended by CERI). ++++ 1.Analysing & Designing Learning Environments for the 21st Century OECD 2. Historical Developments in the Understanding of Learning 3. The Cognitive Perspective on Learning 4. The Crucial Role of Emotions & Motivation in Learning 5. Developmental & Biological Bases of Learning 6. Formative Assessment 7. Technology and Learning 8. Cooperative Learning & Group-work 9. Inquiry-based Learning 10. The Community and Academic Service Learning 11. The Effects of Family on Learning 12. Implementing Innovation: from visions to everyday practice 13. Future Directions OECD ++++ I provide below a couple more links to various interesting CERI projects, initiatives and documents: +++ - -- "Innovation Strategy..." - http://www.oecd.org/edu/ceri/innovationstrategyforeducationandtraining.htm
