This reference is provided by CETIS to help people in the UK HE & FE community to find out about terms used in the field of learning technology standards.
This resource does not claim to hold the definitive, ‘official’ usage of terms: this is a new field, and new terms are being coined, and old terms redefined. What we provide here is a way for practitioners to see how others in the sector are using a term.
Why do some terms have more than one entry?
Some terms are used in different ways – for example, different specification bodies or communities of practice may each have their own take on how a term should be used.
Who contributes the entries?
Members of the CETIS special interest groups (SIGs) contribute definitions. SIG members are mostly from the UK’s Higher and Further Education communities.
How do I add a new term?
You must be a member of a CETIS Special Interest Group to contribute a new entry. The SIG coordinator will provide you with a user name and password.
What if I disagree with an entry?
Anyone can add an annotation to an entry, which other visitors to the site can then view and comment upon. We actively encourage anyone with an opinion on a term to make a comment and contribute to the community’s understanding.
