One of Jisc’s activities is to monitor and, where possible, influence regulatory developments that affect us and our customer universities, colleges and schools as operators of large computer networks. Since Janet and its customer networks are classified by Ofcom as private networks, postings here are likely to concentrate on the regulation of those networks. Postings here are, to the best of our knowledge, accurate on the date they are made, but may well become out of date or unreliable at unpredictable times thereafter. Before taking action that may have legal consequences, you should talk to your own lawyers. NEW: To help navigate the many posts on the General Data Protection Regulation, I've classified them as most relevant to developing a GDPR compliance process, GDPR's effect on specific topics, or how the GDPR is being developed. Or you can just use my free GDPR project plan.

Learning Analytics: Information Filtering

Thursday, September 27, 2018 - 07:16

An interesting observation made by a Dutch colleague earlier this week. The arrows in my standard model of learning analytics (here rearranged and recoloured to match the "swimlane" visualisation of the learning process) all mark "gatekeeper" points where information flow is filtered and reduced. Between Collection and Analysis there’s a necessity/relevance filter so that not all the available data debris are uploaded to the analysis algorithms; between Analysis and Improvement there's a strong filter that removes all personal data and transfers only information on how to improve the learning environment for all; between Donation and Analysis students themselves choose whether to provide data at all; the filter between Analysis and Intervention only passes information about students who could benefit from a particular intervention.

Tutors should always have policy guidance on how to use learning analytics safely; rather than giving them free rein to study and (mis-)interpret the raw learning data as in a recent Dutch example  (machine translation works OK!), our model implements technical controls that support that safe use.
