The Problem:• Assessments based on subjective factors• These factors influenced by many biases• Tracking data has needed expensive devices• Integrating systems was costly & difficult

Data Sources:• OpenLabyrinth internal metrics from cases• H5P widgets• YouTube video analytics• WordPress activity• Biometrics via Arduino

• Heart rate• Galvanic skin response

Conclusions:• Activity streams matter more than

learning objects• xAPI much more nimble than SCORM• Big data applied to personal learning =

PRECISION EDUCATION

Results:• Easy programming via xAPI libraries• Able to combine data streams in ways that

were not previously possible• Emergent, unanticipated patterns in data• Evidence of maladaptive learner behaviours• Simple visual feedback improves behaviours

H5P widgets within OpenLabyrinth platform and WordPress for easy capture of xAPI data

Blended Analytics:• Simple Reporting

From LRS and OpenLabyrinth tools

• Data visualizationsPathways, maps, graphs

• Path analysisMore useful than expected, for both iterative case improvements and tracking learner engagement or confusion!

Devices to extend OpenLabyrinth platform to support data capture via xAPI – galvanic skin response – heart rate

The Approach:• Data capture from variety of sources• Experience API (TinCan) for easy blending• OpenLabyrinth & WordPress

• for content integration• GrassBlade Learning Records Store (LRS)

• For data stream integration
