Activities: Adaptive Quiz
Adam FrancoPlugin in need of maintainers: The sponsor of this plugin, Middlebury College, is no longer using Moodle. If you are interested in updating this module for future Moodle releases and further improving it, please contact afranco@middlebury.edu.
The Adaptive Quiz activity enables a teacher to create tests that efficiently measure the takers' abilities. Adaptive tests are comprised of questions selected from the question bank that are tagged with a score of their difficulty. The questions are chosen to match the estimated ability level of the current test-taker. If the test-taker succeeds on a question, a more challenging question is presented next. If the test-taker answers a question incorrectly, a less-challenging question is presented next. This technique will develop into a sequence of questions converging on the test-taker's effective ability level. The test stops when the test-taker's ability is determined to the required accuracy.
The Adaptive Quiz activity uses the "Practical Adaptive Testing CAT Algorithm" by B.D. Wright published in Rasch Measurement Transactions, 1988, 2:2 p.24 and discussed in John Linacre's "Computer-Adaptive Testing: A Methodology Whose Time Has Come." MESA Memorandum No. 69 (2000).
This Moodle activity module was created as a collaborative effort between Middlebury College and Remote Learner. The latest code, documentation, and bug-tracker can be found at https://github.com/middlebury/moodle-mod_adaptivequiz.

Adam worked on this for me awhile back. I needed both audio files to play and images to show up in the questions. He made some changes to the plugin. I don't know if he updated the Moodle repository though. I got his updated version directly from GitHub. Unfortunately, I was unable to get it to work on my Moodle production site. Interestingly, the images did show and audio played on a clean Moodle development site so there must something conflicting on my production site. I never figured it out and opted for a work around by putting all my images and audio files in a separate folder on the server and then linking to them in the text editor. Not the best solution but one that displays the images and plays the audio for the test takers. HTH
Maybe somebody who experienced with this excellent plugin provide little explanation about usage issue:
- teacher has created one official tag: https://www.screencast.com/t/sjQvMqiWM
- he assign official and additional tags to question, like this https://www.screencast.com/t/Ae6esKsg
- however, during attempt we got next: https://www.screencast.com/t/sjTyCpbOBLIQ :
all question marked as had difficult level 50 (minimal for quiz)
We have tried to follow documentation. What did we do wrong? Moodle 3.2.1
Is the code available on the github link given above is complete Adaptive quiz system project ?
Is there any way to show the question feedback inmediately after the student answers the question? I have tried but no feedback is shown and I can´t do it through permissions.
In practice, how do you envision determining item difficulty? Administer the item a bunch of times, use 1PL/Rasch, and rescale logit value to a 1-999 scale?
