In 1972 Pat Williams became head of a large Reading primary school. When her school closed because of the presence of high alumina cement this led to a project on work with concrete and developing materials with the Concrete and Cement Association. This sharpened her interest in technology in primary school. In 1977 she moved to Basingstoke to take up the headship at a Junior School and in 1981 as a Primary Advisor. David Jinks is currently Project Leader of the British Schools Technology Problem Solving in primary School Project, based at Trent Polytechnic Nottingham.
