On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, 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.
