These case studies begin to capture some of the unique affordances of the personal learning system, PebblePad. It is a tool wholly founded on improving learning and we believe it to be without equal. However, it is just a tool – albeit one which is based on sound educational principles and borne out of extensive pedagogical practice. As a tool it relies on the people who use it to use it knowingly, insightfully and deliberatively. Just as there is an art and a science to teaching so there is both capacity and understanding associated with the best uses of PebblePad.
