About the IEEE LTSC

!   Learning Technology Standards Committee (LTSC)

!   Formal accredited standards since 1996 – Best known for LOM, SCORM runtime

!   Participation free, open, by indivdual

!   Strategy shift to support interoperability lifecycle – Ability to form Technical Advisory Group issuing reports – Ability to sponsor pre-competitive R&D on interoperability (Actionable Data Book project)

Background to the ADB project

!   IEEE LTSC involved with standardizing SCORM

!   Study Group ~2010 about updating standards

!   SG recommendation – No benefit to updating – In a new, rapidly changing technology paradigm – SCORM approach needs to be rethought – Need new foundation, not clear what it is

!   Year long investigation of lots of candidates

Study Group Conclusions

!   Target: a new open approach to mobile learning

!   Key enabler: EPUB 3 as content strategy

!   Key enabler: xAPI for cloud data exchange

!   Challenge: data exchange with IoT/local devices

!   Challenge: global adoption strategy

Why xAPI?

!   Developed by ADL R&D project

!   New approach and successor to SCORM runtime

!   Big data, cloud data solution

!   Common “experience statement” format that can be constrained by vocabularies

!   On ramp to a semantic data solution

!   Commercial interest and adoption

!   Potential for IEEE standardization

ADB 2015 Goals

!   1. Report on ADB technical architecture

!   2. Use cases to illustrate ADB generality

!   3. ADB Proof of Concept demonstration illustrating communication with cloud, IoT, and mobile platform capabilities

!   4. A survey to assess ADB viability as a globally available platform for mobile learning

!   5. An ADB workshop at an appropriate venue

ADB Activity Model

!   Updates 20 year old AICC CMI/ SCORM concept

!   Minimalist approach to coordinate data exchanges

!   Three entities – Activity: a unit of completion – Location: unit of navigation within and activty – Activity Set: a collection of actvities

!   Three phases/events per entity – Before, during, after

!   Under development – feedback welcome

ADB Activity Model: Why?

!   Motivate by considering xAPI capabilities as appropriate in different content contexts

!   The xAPI Statement API – Can be used for learner experience/performance data – Can be used for annotations – Can be used for scientific data

!   The xAPI Agent Profile API – Can be used to get/store user preferences

!   The xAPI State API – Can be used to get/store activity data

Mapping the Activity onto EPUB 3

!   Our best quess … two options

!   Widget – ADB Proof of Concept last Spring – Limitations for our requirements

!   Collection/Distributable Object – Appears better option, on the drawing board – Two level collection hierarchy – Activity role containing location pages – Activity Set role containing Activity collections

Relationship to EDUPUB

!   Out best quess ….

!   ADB – HTML5 content unit is the Location – Focus providing data exchange capabilites to the Location – Silent on HTML5 content conventions

!   EDUPUB defining HTML5 content conventions

!   Appear to be complementary technologies

Relationship to LTI and Caliper

!   Our best guess …

!   LTI – A tool essentially an embedded Web site – Different approach to communication than xAPI – LTI and xAPI are complementary

!   Caliper – Outcome data models for different kinds of activities – Needs a transport mechanism – xAPI 100% appropriate implemented solution
