Granularity is best described as creating levels of data, with full control over who can see what. Stodd (2012:45)
Failing to find notes on granularity in his own blog while reading a son to be published book on social learning by a colleague - I stumbleupon this. The best way to learn, in my eBook - serendipty, vicariously, exploratority, but with a mix of familiar and new territory.
Where, courtesy if his link to JISC I find a satisfactory answer:
Features: planning at different levels of granularity – activity, session, module, programme. customisation of terminologies to adapt to local institutional requirements. consideration of teacher time and learner time as significant parameters for learning design. updating of information in all stages after changes made in any one stage. externalising decisions made in designing through visual representations.
