My work is largely educational. I am developing a database of questions that are used to help students to extend their understanding of subjects relevant to leaders of Engineering Design projects: Maths, Electrical, Mechanical, Civil and Aeronautical Engineering, and Computer Science. Linked to this concept of a database of questions are sets of supporting learning materials. All available on the web. In order to manage all this data I have developed classification schemes. A current project involves the development of a system, TAL, to allow students all over the world to take multiple choice tests over the internet.
