Learning Analytics

”Learning Analytics is the measurement, collection, analysis and reporting of data about learners and their contexts, for purposes of understanding and optimizing learning and the environments in which it occurs.”

http://www.solaresearch.org

”Learning Analytics is about collecting traces that learners leave behindAnd using those traces to improve learning”Professor Eric Duval http://erikduval.wordpress.com/2012/01/30/learning-analytics-and-educational-data-mining/

Learning Analytics – working with data and toolsDr. Grace Owen, Open Universities, Australia http://www.youtube.com/watch?v=XjcSfcahjWY, says that LA is about ”making a meaningfull difference”. She says about the challenges with size and storing: ” If we pulled one week out of learning managementsystem of data from prep students, which were 34 students, it was a tb of data, we are talking massive massive data, so the trick is: how do you get the data? And how are you getting it, is it unstructured or structured, what are you going to do with it and once you get it where are you going to put it?”

Key areas, when working with data: First to get hold of the data, storing them, then cleaning them – data is messy, then maybe integration with other datasets, analyzing them and finaly vizualisation and presentation in a format that makes sense and is understandable.

Dr. G. Owen highlights the following quistions to consider for an institution working with data: • Who owns learner-produced data?• What are the conditions under which an institution jumps data silos(i.e. blending analytics from

student information systems with social media analysis?• Who has access to the analytics an institution conducts on learners?• Or, for what matter, who owns the analytics(if it is individual student data worked through an

institutional algoritm, who owns the outcome?)

• LASI13: Who owns the data ? or better What does it mean to own the data?
