For a beautiful description of how reading and writing is really learnt by young children, here is Chloe’s story by Carole Bloch.
I am chairperson of Quaker Service (Cape), and am on the board of the Association for Educational Transformation (ASSET). ELRU, Philani, Nalibali, and The Little Hands Trust are other inspiring local organisations (I was on the Boards of ELRU and Philani for many years). I am an avid fan and supporter of the Pro Cantu Youth Choir. I am an amateur photographer on my mountain walks; the photos below are from an exhibition I held in 1999. And here is our joint lamentation about the destruction of shade trees in Cape Town (walking in the shaded forest in Cape Town has been a privilege I have enjoyed for 50 years, now a thing of the past: they have been destroyed by fynbos fundamentalists).
Finally, for those interested in my views on science and religion, here is a paper I wrote on the Quakers a long while ago, and here is my Backhouse Lecture to the Australia Yearly Meeting of the Quakers; and here is a paper on fundamentalism in science and religion. For much evidence of scientific fundamentalism, see various very informative links here as well as the writings of Alistair McGrath.
