QTI timeline
- Conceived in 1999, v1.0 released in 2000- Updated in 2001 (v1.1) and 2002 (v1.2) to improve
and extend the model- By 2003 it was clear that a major revision was
necessary, a quick fix (1.2.1) was followed by a complete rewrite
- QTI v2.0 was published February 2005- QTI v2.1 (PD2) published June 2006- QTI v2.1 (PD2) – addendum published March 2008- QTI v2.1 (Final) expected ??
QTI 2.1 Status
- Collected comments on Public Draft- Released errata document
- Profiling discussion- Still ongoing, some work done on CC K12 profile
- Interoperability demonstration- Has not taken place yet
- Because of that – no date set for final release
Project team
- Meeting on monthly basis until December 2008- As of January 2009
- Co-chair Steve Lay stepped down- Co-chair Pierre Gorissen stepped down
- IMS are looking for a new chair, issues should be raised directly with:- Kevin Riley, IMS- Lisa Mattson, IMS Operations
Changes in most recent update
- Esoteric backwards-compatible changes:
- Outcomes can also be substituted in Maths and Objects (not just
template variables); minor schema change
- Minor changes to rules of substitution in MathML to support operator
and variable name parameterization; no schema change
- Deprecation of special duration-based operators; no schema change
- Recommendation to allow extensions at ‘rule’ level within processing
elements; more permissive schema extensions
- Other wording changes to provide clarity with no intended changes to
meaning or schema
- These are only recommendations from this
community – they are not agreed changes!
