3. Why Experience API, xAPI
● Ready data integration no matter where learning happens
● Record any new experience without limitation, driven by
community
● Gain deeper insights into learning process, accumulate
collective intelligence for different stakeholders
● Data reuse is very efficient (data is the new oil)

5. Why xAPI is a
game changer?
Freedom of data flow
Distributed Learning Ecosystem
Unified data structure and document
APIs (state, activity, learner)
Specialized technologies working
together without pain
Freedom of learning design with best
breed of choices & innovations

6. Examples of Developments Enabled by xAPI
Social layer (Both
Actors and Objects
are networked)
Gamification layer
or Behavior Engineering
Technology
Self-paced & adaptive
learning, automated
learning flow across x
Integrated data &
experiences across
platforms / resources
An ecosystem of innovative applications & analytics, and creative uses can grow
out of Data Lakes. (because of data interoperability facilitated by xAPI)

7. Build projects upon
analytics backbone
with
data structure,
Semantic,
visualization
interoperability
Standardized xAPI Profiles/ Recipes /
Vocabularies for basic modules
Standardized visualizations design
Embeddable visualizations to be
monitored along with other data for
goal management
xAPI implementation & statement /
viz design for case-oriented behaviors

8. Hierarchy Design for Effective Visualization & Analysis
We provide standardized xAPI profiles / recipes for standardized visualizations.

9. Customized
Dashboards
A dashboard is a visual display of
the most important information
needed
to achieve one or more
objectives
that has been consolidated on a
single computer screen
so it can be
monitored at a glance. (provides an
overview)

10. Process Matters!
From content-oriented to experience-oriented design
Data + Design = Behavior Engineering
From fix mindset to growth mindset
Return process data to learners in real time

<= Can be drilled down
View each person’s
time spent
Overall time spent in each activity type for selected group
Overview of Time Spent on All Activities

15. Overview on Timeline
1. Group vs. individual
2. Filtering by activityType, activity id, verb, profile

16. Video

17. eBook (IEEE Actionable Data Book project)
Interactive chart showing every actions ever happened on each page,
can be drilled down to see who, when, what note/highlight content,
quiz answering records, video watching records
Time spent Heatmap

18. Quiz Answering Records
Encoding visualization with
granular records and standards,
can be drilled down
Help catch patterns, problems
and competencies efficiently
Aggregate all practice data from
different sources
Assessment item analysis
● P-Value
● Discrimination
● Sequence/context analysis ...

19. Quiz Answer Process
(drilled down)
Use hint/feedback? how long?
Time spent
How many tries?
Which device?

21. Multivariate Analysis
Which verb counts matter? (“noted” in this case )

22. Correlation Analysis
In this example, learners in 4 quadrants have different needs
To correlate and find factors that matter to your metrics

23. See who’s learned this
-- a peak of social layer on top of different activities

24. Verb cloud
(color matched to the taxonomy level)
Verb taxonomy visualization (points reward higher order verbs)
Hint : Charting Verbs stat. vs. time can see behavior trend

25. Connecting with
Learning Analytics
Community

=> Active Learning Squared

26. Our Current User Base
This project is being implemented in Taipei city, Taiwan. All
teachers and students, about 350,000 in number, in Taipei city
will be using this solution (later other areas will join); the public
department is working towards building an ecosystem (from
collaboration of public departments, schools, vendors, scholars,
and developers) based on xAPI standard and open learning data
as Open Data.
