HOW HUMANS LEARN TO THINK MATHEMATICALLY
This book formulating an overall framework to explain and predict how humans learn to think mathematically has now been published by Cambridge University Press (USA) in September 2013. I was allowed by the publishers to place the first chapter of the book in draft copy here. The price quoted for the book has varied over the last few months. It is now confirmed as paperback $39.99, Hardback $99.99. The best deal I have found, including post and package worldwide is from The Book Depository. (A few errors in the first printing are listed here.)
It identifies three essentially different long-term developments of mathematical thinking involving:
The overall linking concept is the notion of crystalline concept. This is a concept with strong connections that are implicit in a given concept, for instance the notion of 'isosceles triangle' in geometry which not only has two equal sides, it must have two equal angles and other properties, such as symmetry about the line bisecting the vertex, or 'five' in arithmetic which not only equals 3+2 or 2+3 or 72, but also, if 3 is taken from 5 then 2 must be left, and so on. This idea develops in appropriate ways in each of the three worlds of mathematics and leads to connections between mathematical ideas that gives mathematics its coherent structure.
The transition to new areas of mathematics is built on experiences that were met before and in a new context may be supportive (e.g. 2+2=4) or problematic (e.g. 'take away makes smaller' in the context of negative quantities). Supportive met-befores allow appropriate generalization and give pleasure in operating in new contexts. For a confident individual a problematic met-before may cause frustration and a determination to conquer the problem. For a less-confident individual, a problematic met-before may cause anxiety and the desire to avoid the problem. In the latter case, the individual may seek to learn procedures by rote to be able to pass tests. If successful, this gives a new kind of pleasure in passing examinations, but it may not promote a flexible way of thinking and later lead to longer-term difficulties.
The framework focuses on cognitive and emotional development of mathematical thinking from the viewpoint of the learner while remaining aware of the crystalline nature of mathematics at all levels. It blends with other theories to reveal how approaches suitable in one context may be problematic in others. It encourages theorists to become aware of their own met-befores that colour their opinions and offers an analysis into current controversies in mathematics education that arise from the views of different communities of practice.
Earlier papers that eventually led to the full framework are given below. Important papers are 2010b on met-befores, 2011a on crystalline concepts, and the keynote talk 2010c on the effects of emotion in mathematical thinking.
