I found the exploratory techniques described in this course to be useful. The course content was well explained and I found the notes to be useful in completing the assignments.

This is a pretty poor show and lazy effort by the suppliers. The assignments don't cover most of the material, and seem to be a token attempt to have something to test. I got full marks BTW - so hopefully no... This is a pretty poor show and lazy effort by the suppliers. The assignments don't cover most of the material, and seem to be a token attempt to have something to test. I got full marks BTW - so hopefully not a sour grapes thing, more a disappointed concern that my time could have been better spent. Although some of the later material covers e.g. clustering, the (much earlier) assignments really test how to extract data and plot graphs. The problems - such as they are - may be because of the 'learning opportunity' presented by reviewing the work of others, which is the basis of getting the marks needed to pass. This may have learning benefits, but is the cause of a number of issues. Firstly this front-loads all of the assignments and evaluations to the start, hence missing the opportunity to test the advanced and more important material. Secondly there are the vagaries of peer assignment, with all the vague misunderstandings that arise (if the discussion forums were a guide). Thirdly, there are the apparently random and inconsistent submission methods - which are really a test of self-organisation and paying attention to the instructions. I suppose my final criticism is the removal of the Statement of Accomplishment, and the commodification and push towards the paid-for certificates. Given the (lack of) quality of this module, the emphasis away from knowledgeable assignment evaluation, and the problems some students had formalising the signature track process (perhaps not JHU's fault), this is something I will be wary of in the future. From my experience of other MOOCs there is no reason this could not be significantly improved, test students on useful 'stuff', and award a mark on the basis of the subject stated in the title.
