This website is the outcome of a project involving an international team of 12 active researcher-users of the Knowledge Quartet, with the aim of clarifying the intention of each of the constituent codes.
The project is described in
Weston, T.L., Kleve, B. and Rowland, T. (2013) Developing an online coding manual for the Knowledge Quartet: An international project. Proceedings of the British Society for Research into Learning Mathematics 32(3) pp. 179-84 http://t.bsrlm.org.uk/IPs/ip32-3/BSRLM-IP-32-3-31.pdf
The site is in continuous development – the intention is to add other scenarios of the same kind over time, in the same format.
