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)Using interaction data for assessment

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
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
