In other words, qualitative and quantitative evaluation. ‘Granularity’ as I understand it is the amount of detail which research can capture, from the the fine-grained data from interviews and focus groups, to broadbrush figures on numbers of website hits gathered through such programmes as Google Analytics. These topics came up at the JISC evaluation training day this week, where delegates talked about how to measure impact of resources.
One important element is baseline data, to give a standard against which to measure later improvement (or lack of it) after online resources are available. Baseline data is not always available or usable. For example, at Reading documents with baseline data give figures for university modules which use the Museum, but use of online resources will not really be measurable against these. On the other hand, we are gathering qualitative data through interviews with students.
One resource is an online version of a lecture which is given each year to students. This year I am thinking of giving them the online resource instead, and have just drafted a questionnaire asking them for responses.
