Open Source Schools will be presenting a BETT seminar on 'Creative Computing with Open Source' at 15:45 on Wednesday 13th January. We will showcase a number of case studies about how school students are learning to program and contribute to the development of open source projects using a range of free, downloadable tools. Examples range from Scratch programming in primary schools, through Greenfoot in the secondary curriculum to the development of modules in PHP for web-based applications such as Moodle.
