Project Aims
� The project will provide a documented and packaged version of
standards-compliant assessment delivery tools
� Learning Tools Interoperability (LTI) connection between popular
VLEs and delivery software
� QTIWorks rendering and responding engine � QTIWorks rendering and responding engine
� The tools will be distributed to the project’s client partners
� Kingston University,
� Harper Adams University College
� University of Strathclyde.
QTI – what’s that?� Question and Test Interoperability specification
� Version 2.1 is now final
� Standard for representing questions and tests
� Many implementations worldwide:
� UK, France, Netherlands, Germany, Spain� UK, France, Netherlands, Germany, Spain
� USA, Mexico
� Korea
� Used by
� Educational institutions for internal assessments
� Examination authorities (Scotland, Netherlands, Germany, Korea)
� Publishers for online content associated with textbooks
Why use QTI?� Interoperability:
� Share assessment resources with colleagues in same or other institutions
� Efficiency, less reinvention of wheels
� Economical – costly to produce good resources, so share and repurpose
� Preserve materials to prevent loss when changing systems� Preserve materials to prevent loss when changing systems
� Ensure content separate from software
� All these contribute to SUSTAINABILITY
� Flexibility:
� 20 or so input types – and extendable, e.g. Maths
� Several inputs in one question – engaging resources
� Targeted, individualised feedback, related directly to input

Installation?
� LTI – Moodle 2, newer versions of Blackboard and Sakai VLEs
are already LTI-enabled.
� LTIQuizzes – a single .war file needs to be copied to a Tomcat
server, then an XML configuration file is edited to add the LTI server, then an XML configuration file is edited to add the LTI
details (server names and shared secrets).
� QTIWorks – online demo at
https://www2.ph.ed.ac.uk/qtiworks/ , .war file expected
soon for institutional installation on Tomcat server

The following slides are provided in case the live demo
is not available...
They are quite mathematical in flavour, but resources
from other disciplines work just the same!

Uploading an Assessment� Content of uploaded assessments –question or test – can
be changed (e.g. fix a bug)
� Date of last change is displayed
Setting Up Assessment Launch Data� Saving a delivery with LTI enabled creates launch data
� Data is pasted into Moodle 2 External Tool dialog or
equivalent in other VLEs
Test: Algebra 1
This test is the one used in the Maths T1 topic Algebra 1. It is also
in the demo course.
Question in a Test
The indicator at top right shows the question status. No feedback is
visible during the test – students have been using these randomised
questions in formative mode for several weeks. Candidates return to
the list of questions to select another question.
