In her report she analyses a number of MOOCs over recent years using low / medium / high for each of the dimensions. "I would argue that at a glance this classification framework gives a far better indication of the nature of each MOOC than the simple classification as xMOOCs and cMOOCs."
I think it is also a useful classification for exploring the purpose of design features of any particular online course especially where platform constraints are being compared.
