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

QTI in Moodle 2 – Question

QTI in Moodle 2 – Question with Solution

QTI in Moodle 2 – Maths Input

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.

Test feedback & review

These are the two parts of the feedback and review page; the scores

for the questions are displayed and the candidate may return to see

the questions and their input.
