These presentations are also included in a whole series of open resources I have at http://goo.gl/8YLrDf
Course: Computer Science 2014+
This course aims to provide student booklets and teacher presentations for all areas of the new IB Computer Science course. The resources tend to be biased towards JAVA and Option D (OOP). The content is in no way endorsed by the IB they are simply resources written by me to support my teaching.
