I have been a great fan of Richard Allaway and Alan Parkinson for a long time now and I’d safely say that (amongst other geography greats like Tony Cassidy , Noel Jenkins and Daniel Raven-Ellison ) they have had a heavy influence in my outlook and teaching. So, it;s great to see that the pair have ben collaborating to produce a series of eBooks aimed at teachers of the International Baccalaureate. Having downloaded the free Extreme Environments book , there seems to be a wealth of material relevant for those teaching at any exam level and even at Key Stage 3 in the UK. I’ll be keeping an eye out for the next instalment. I especially like the interactive reviews, such as the one pictured above, and can see this as being a great revision tool for our own GCSE students. I’ve already added the book to Priory Geography’s iPads and iPhones.
