They say a little knowledge is a dangerous thing. They are completely wrong. We all have only a little knowledge. The dangerous thing is being satisfied with that.
I've been teaching online with the OU since 2000. My subject areas are business, arts and social sciences. I also use ICTs in my other job as a consultant in healthcare technology management in low resource settings. I do bits and pieces of work for the Liberal Democrats. I am currently mourning the loss of Lewes's best ever MP, Norman Baker. I am usually online for about ten hours a day, living in my airing cupboard much of the time. Despite this I have a healthy skin colour and do not lack for company.
