Applying big data and analytics in education
Learning analytics is themeasurement, collection, analysis andreporting of data about learners and theircontexts, for purposes of understanding andoptimizing learning and the environments inwhich it occurs. Society of Learning Analytics Research
“A university where staff and studentsunderstand data and, regardless of its volumeand diversity, can use it and reuse it, store andcurate it, apply and develop the analytical toolsto interpret it.”

We can make great progress with analytics asindividuals, but the nature of ‘big data’ requiresa systemic focus

What is behind a simple visualization?
Tools for analytics- Single functionality tools (SNAPP)- Multi-function tools (ManyEyes, Gephi)- Visualization (Tableau)- Existing research tools (SPSS, Wolfram)
Acquisition: how do we get the data – structuredand unstructured?Storage: how do we store large quantities?Cleaning: how do we get the data in a workingformatIntegration: How do we “harmonize” varying datasets togetherAnalysis: which tools and methods should be used?Representation/visualization: tools and methods tocommunicate important ideas
Many tools are currently stand alone and singlefunctionality(anyone remember learning managementsystems in the late 1990’s?)
PlayersStartups (Grockit, Knewton)Existing vendors (Cisco, Catatel)Systemic learning analytics players (iStrategy)(they get bought up quickly)

To date, asystem-wide open source analytics platformis NOT available.We want to change that.
Given how important analyticsare…maybe we should start with openness
The Vision:Open Learning Analytics Architecture
OLA: An open, extensible platform for researchers, educators, and administrators for broad-scale analytics in education and learning.
Principles of a systems-wide analytics tool1. Algorithms should be open, customizable forcontext2. Students should see what the organization sees3. Analytics engine as a platform: open for allresearchers and organizations to build on4. Specific analytics strategies and tools: APIs5. Integrate and connect with existing open tools6. Modularized and extensible
Privacy & EthicsJust because we can…should we? Particularly due to the exponential insightPossible with integration of multiple data sets
