There will be a digital divide between Higher ED organizations with data centralism and those without. 

Those organizations with data centralism will have a significant competitive advantage related to Learning

analytics services.

OU UK Are we on the wrong side of an emerging digital divide for researchers and later practitioners?

Before 2018, we aim to become a world leading centre of learning analytics research, whereby state-of-the-art evidence-based research leads to advancements of the learning analytics field, transformed into successful methods, approaches and commercial products. Furthermore, we need to ensure that research is effectively translated into cost-effective transformations of the core OU business programme. By developing micro-

level experiments in the Jennie Lee Research Laboratories and meso-level interventions within the core business model (e.g., Student Experience Project PVC LT) together with the two other research programmes within IET

(Innovative Pedagogy, Learning in an open world), we aim to become the leading centre of excellence in learning analytics as recognised by REF 2020.

•Standards- xAPI / Caliper- LTI

•Requirements and hackathons- Look at all that duplication of functionality and potentially relearning others lessons

•Retention systems: Open Academic Analytics Initiative- Predictive Model Markup Language (PMML)

•Dashboards: Open Dashboard•Broad community and policies– OLA (SoLAR, LACE, JISC, Apereo LAI, SURF, UvA)

•Learn from formative examples: JISC national Freemium LA Service

Building large scale systemsThe recipe

● Gathers student activity in a secure repository● Standard protocol● REST like service for writing and querying● Can act as the glue for Learning Analytics

Projects● Good introduction at:

xAPI Benefits

● Decouples activity streams from specific software (centralizes data)

● Standards approach● Scalable - But {the LRS market needs to mature}● Structured data - But {depends on what you send}● Community● Clean data for research● Growing market enthusiasm● Can work well with LTI dashboards

Learning Tools Interoperability (LTI)

•Learning Tools Interoperability•Stand alone application that appears inside LMS’s, portal’s etc•Great for scalability, performance, migration, separation of concerns

•Large list of compliant tools•Uses a secret key to secure communication•LMS passes context information•Examples: UvAnalytics, Opendashboard

•Homepage: http://www.imsglobal.org/lti/index.html

Context Information

 resource_link_id: is a key for the content.

 context_id: is the key to the course.

 user_id: is the key to the user in the PIWIK database.

 roles: Is the set of roles the user has in the course.

 lis_person_contact_email_primary: E-mail address of user as defined in the Blackboard Database.

DashboardApplication

LTI

● Scalable● Lazy coupling● Has the potential to

work across applications

IMSGlobal – Caliper

•A competing standard against xAPI, but does more

•You can find the exact details here: http://imsglobal.org/caliper/index.html

•Public release very near.•Recommend keeping track

Hackathons and open dashboardRequirements count

• Collecting requirements across hackathons

• Sponsored by SURF and UvA- 2 days. 4 teams. Free to participate

• LAK15 Conference- 2 days. 4 teams. Conference charge to participate- http://lak15.solaresearch.org/hackathon- https://confluence.sakaiproject.org/display/LAI/

Learning+Analytics+Initiative- https://github.com/Apereo-Learning-Analytics-Initiative/- Open dashboard - Open LRS

• More hackathons to come

Open Learning Analytics

With learning analytics poised to become a mainstream technology, higher education leaders from around the world came together following the Learning Analytics and Knowledge (LAK) 2014 conference in Indianapolis, Indiana for an Open Learning Analytics (OLA) Summit.

European OLA summit Nov 2014 in Amsterdam (LACE, Apereo supporting)

• http://solaresearch.org/initiatives/ola/

• In progress

• Heavily influences emerging frameworks such as:- Apereo Learning Analytics Initiative- Jisc National Freemium LA infrastructure
