 Computer adaptive practice activity module for Moodle
 
 ## What is it?
 
-CAP is short for /Computer Adaptive Practice/, a term coined by [Klinkenberg, Straatemeier, and van der Maas (2011)](https://www.sciencedirect.com/science/article/pii/S0360131511000418). 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.

 ## History
 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](https://github.com/MathGen/oppgavegenerator), written as a standalone server in python.
