Derek Bell, Chief Executive of the Association for Science Education, was appointed professor of education in July 2007 by the College of Teachers (formerly the College of Preceptors), which was the first institution in the UK granted the powers, under its Charter of 1849, to appoint professors of education. Today there are only four such posts at any one time awarded to individuals who 'demonstrate qualities of professional leadership that have been recognised widely within the profession as substantially furthering the aims of education'. As well as contributing to the work of the College, new professors are required, as is the custom in any academic institution, to present an inaugural address to their peers. SSR is proud to reproduce this transcript of Professor Bell's inaugural lecture, which carries important messages for everyone involved in science education now and in the future.
