Computer adaptive practice activity module for Moodle
CAP is short for Computer Adaptive Practice, a term coined by Klinkenberg, Straatemeier, and van der Maas (2011). Where most LMS quiz systems give the students a fixed sequence of questions regardless of how well the students answer, a CAP system will estimate student ability based on their answers, and try to find questions at the right level of difficulty.
In CAPQuiz, the proficiency is measured by a rating. Good answers increase the rating, and bad answers decrease it. To increase the rating, students need to give good answers more of than bad ones over time. We have used CAPQuiz as a mandatory assignment, where the students have to reach a certain rating in order to be allowed to sit the exam.
Estimating question difficulty is known to be difficult. CAPQuiz automates this process to some extent. The question author must provide an initial estimate, but CAPQuiz improves the estimates based by comparing how the same student answers different questions. Hence the rated question sets will improve over time.

- CAPQuiz in the Moodle Plugin Repository
- Users have to take care not to delete questions used by instances of CAPQuiz. At present, there is no mechanism to prevent accidental deletion.
- Issues have been reported with the class list in old quizzes after upgrading to the most recent versions. New quizzes created in the new version seem to work as they should.
- Further testing is required, so if you use CAPQuiz, please report any trouble, preferably using Github issues.
The idea of an adaptive learning system at NTNU in Ålesund (then Ålesund University College) was first conceived by Siebe van Albada. His efforts led to a prototype, known as MathGen, written as a standalone server in python.
The first prototype was tested by several lecturers, and was well received by students. There were, however, many problems which we lacked the resources to handle. Most of these problems had already been solved by Moodle and the STACK question type, and it made sense to reimplement the adaptive quiz functionality in Moodle to take advantage of this.
CAPQuiz includes the work of many contributors.
