About the e-textbooks with embedded assessment experiment
The practical difference between books and text books: formative
assessment
Goal of the experiment: making electronic textbooks scalable,
effective and robust
Scalable processes and standards
Why use interoperability standards?
Balancing effectiveness with robustness
Most interactive
Most devices
Static QTI HTML inside EPUB3OK experience
Long lived
Works anywhere
But:No feedback
No analytics
No results
(unless the user clicks a link)
QTI HTML + javascript inside EPUB3Good experience
Reasonably long lived
No server infrastructure
But:No results or analytics
May need some work with e-reader vendors
EPUB3 to online quiz tool via IMS LTIBest experience
Secure
Quiz results return to college, analytics possible
But:Potential longevity issues
May need work with e-reader vendors
Needs an analytics ID transfer solution
Readium
QTIWorks results
iBooks; offline, javascript widget
Adobe Editions- static HTML
Link to LMS from static HTML
Demo
Valid EPUB3 ebook
Uses the same valid IMS QTI 2.1 item in all contexts
QTI 2.1 item is used in static and dynamic HTML5 forms using
round-trippable transforms
E-reader systems are stock, current versions
Differences with the current IMS EDUPUB work
The experiment doesn't stream activity data (but does report
online assessment data), the IMS one does
The experiment works on a wide range of stock e-readers, the IMS
requires it's own desktop-only reader
The experiment requires an out-of-band user ID solution, the IMS
one can ask the user to divulge their device ID info
Further work
Test the solution beyond iBooks desktop, Readium desktop,
Calibre and Adobe Digital Editions 2.0
QTI 2.1 to HTML transforms areCurrently limited to multiple
choice and fill-in-the-blank
Transforms need tweaking for this application
QTIWorks results reporting to 3d party LMS needs testing
QTIWorks might benefit from a better mobile user interface
Conclusions
EPUB3 combined with QTI 2.1 can provide formative assessment in
e-textbooks that is scalable, effective and robust
Fallback mechanisms in EPUB3 enable engaging experiences in rich
clients, whilst still supporting basic readers
The standards don't require change
