OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
In this presentation, I will provide an overview of adaptive testing—both at item level and at module level— and I will discuss the challenges & opportunities for the application of the adaptive algorithms to high-stakes assessments. I will discuss the issues related to item parameter estimation and comparability of test scores across administrations, as applied to both traditional and digital-first tests. I will illustrate the item-level adaptive digital-first test with the Duolingo English Test.
