My secondment through HTI from Hampstead School, where I taught A Level Maths and Computer Science, to the Tesco SchoolNet 2000 project, where I facilitated the development of pupil-generated web pages, was the fulcrum that shifted my career focus from the classroom to the Internet.  Meeting  many more people at the interface of business and education than had been possible when based in a school revealed exciting opportunities to explore the application of new technologies for learning during an explosive period of online activity.  The choice of returning to teaching Maths or taking up an invitation to join Ultralab at Anglia Ruskin University in January 2000 was influenced by professional development in leadership during the secondment and inspired by the lure of the world wide web.  The secondment with Tesco involved hours of driving to stores and schools to introduce teachers to the Internet; a decade later I use social media and online communities of practice to communicate around the world about professional development.
