It was Dapper that was great. And now I have seen Twitter Earth and Dipity – two extremely intersting “mashups” that essentially give you a visual story of your activities. To give you a flavour, I just had to link Dipity with this blog to get a visual timeline! You could even get a spatial map of where you performed an activity. From a learner tracking perspective, such tools could be an important component of being able to track learner activity in a given learning context. The instructor or guide could not only measure the level of the learner activity but also traceback to time taken to complete a particular activity (maybe even follow a learner’s chain of thought?).
