How H2020 European ProjexAct is proposing to use xAPI for doing gaming learning analytics (GLA) with serios games. It describes the full approach from research to models, to methodologies to GLA supporting software to examples.

RAGE: creating the Gaming Learning Analytics
infrastructure
H2020 RAGE project will simplify the process of
Serious Games creation with ready to use assets
• 20 EU partners, 9 M €
• Game trackers (Unity3D, javascript)
• LA server infrastructure and services
• Basic analysis and visualization of LA data
• Extensible architecture
• Standards support (e.g. xAPI)
• Open code (github)

What it needed to generalize
xAPI in serious games?
• Game developpers should clearly understand the benefits of using
xAPI for learning analytics
– Added value, ROI
From ad-hoc LA solutions to generalizable ones ….
• Clear and sound scientific approach
• Learning Analytics Models applicable to games (Gaming Learning
Analytics Models)
• Methodologies that reduce the complexity of applying GLA models
• GLA Software
– Game Trackers
– GLA infrastructure to collect, analyze and exploit the LA data
• Examples to learn from

Interactions tracked by serious
games
• Completion
– A level/stage/puzzle was completed or not
– Completion achieved (percentage)
• In-game choices
– Questions with multiple answers
– General choices where the player must select action among several
options
• Meaningful variables
– Score
– Number of deaths and kills
– Coins

6. Co-funded by the Horizon 2020 Framework
Programme of the European Union
Interactions tracked by serious
games
• Meaningful actions
– Clicked exit button
– Asked for help
• Custom interactions
– Game-specific interactions, only relevant in the concrete serious game
Already started the cooperation to contrast our approach with ADL

RAGE, serious games and
xAPI
• Define interactions model to assess serious games
• Create a xAPI vocabulary to represent the model
– Repurpose existing verbs and activities
– Create verbs and activities where needed
– Create extensions where needed
• Define analysis for the model
– Simple metrics processing statements (serious game agnostic)
– More advanced analysis based on serious game goals
• Provide a set of default visualizations for data
