  35. 35. Girls not in Computer Science 'Geek' perception of computer science putting off girls, expert warns Prof Dame Wendy Hall Computer Science had to be "given a buzz" to all pupils in primary schools and children needed to be shown how vital the discipline is to society. "Girls have been further put off by dumbing down computing to IT literacy ... They think that if they study computing they are going to become secretaries." Separate statistics reveal that just 148 girls took the AQA exam board's computing A-level – seen as one of the most difficult computing A-levels – last summer, compared to 2,123 boys. Five years earlier, 3,628 boys and 297 girls took the exam. http://www.guardian.co.uk/education/2012/jan/10/fewer-girls-taking- computer-science?newsfeed=true

If computers are to be used for good, then I is essential that everyone should understand what they can do. …. because out of understanding comes judgement” ….changes in Society that computers will bring …. not going to be comfortable, but it is the job of those of us in the University to ensure, by research and education, that they are not catastrophic. That is why I am in the game. And to be honest, it is great fun too!”
