ALiSe CAT Quiz

The plugin local_catquiz implements full Computer Adaptive Testing (CAT) capabilities in Moodle. Using common one-dimensional Item Response Theory (IRT) models, test takers are presented only with questions that fall within their identified ability range, based on the answers they give.
The plugin can be used with all types of questions in Moodle that allow for automatic scoring (e.g. multiple choice or cloze text). The plugin supports the following common Item Response Theory (IRT) models:
dichotomous questions (only account for right or wrong answers)
Rasch-Model (1 parametric logistic model)
2PL-Rasch-Birnbaum
3PL-Mixed-Rasch-Birnbaum
polytomous questions (account for right, wrong and partially correct answers)
Graded Response Model and Generalized Graded Response Model
further models will be realized in upcoming versions
The plugin further enables the creation, administration and modification of different scales on which measurements are taken. For this purpose, the plug-in creates a new role “CAT Manager”, which is authorized to perform these administrative tasks.
Finally, the plugin allows to pursuit different test strategies:
running a “standard” CAT test
adaptive diagnose for weakest/strongest ability in selected (sub-)scales
adaptive diagnose for all given (sub-)scales
semi-classical diagnose for all given (sub-)scales
classical testing (ask all questions), but evaluation with IRT
Dependencies
For using this plugin, you are required to install the following plugins:
mod_adaptivequiz – the activity from which a CAT test can be started (vers 3.1 onwards). Please use the the wunderbyte fork until our changes are integrated into the upstream plugin (in progress). This branch already includes the subplugin adaptivequizcatmodel_catquiz , which serves as a bridge between mod_adaptivequiz and local_adaptivequiz
local_wunderbyte_table ) – database and tables handling
