The theme of PebbleBash 2012 is ÔMaking the CaseÕ, a theme that I have not overtly addressed at all in this Introduction. However, I believe that there is no better case to be made for any teaching and learning tool than to demonstrate its growth and the growth of its user community Ð not just growth in size and numbers but more importantly, growth in terms of shared understanding, maturity, and successful outcomes. To assist you to put this case to the Ôpowers that beÕ in your institution or organisation, each case study in this book concludes with a summary of key points that Ômake the case for PebblePadÕ. Put together, they start to present a powerful argument for the benefits of effective PebblePad implementation.
