MOCAH Tools for IMS-QTI 2.1 Odette Auzende, Hélène Giroire, Françoise Le Calvez MOCAH team (LIP6) University Pierre et Marie Curie - Paris

MOCAH objectives To help teachers to create math exercise templates and tests for secondary schools To express exercise templates and tests in the most interoperable format: IMS-QTI 2.1 To play exercise templates and tests on most Web servers without use of web- service

The QTI Editor Allows teachers to create easily math exercise templates with three types of interactions: textEntryInteraction, choiceInteraction, inlineChoiceInteraction Includes an editor for math formulae and a QTI Constraint Editor for declaration of constraints between parameters Generates an IMS-QTI 2.1 file

The QTI Editor Parameters Variables (x,y,z…) Lists Summary of the exercise template Statement: textEntryInteraction or choiceInteraction or inlineChoiceInteraction Next step: declaration of constraints and Feadbacks with QTI Constraint Editor Responses

The QTI Constraint Editor declaration of parameters declaration of constraints declaration of lists

The QTI Web Pages Generator Takes as input an IMS-QTI 2.1 file corresponding to textEntryInteraction or choiceInteraction or inlineChoiceInteraction Generates a pair of PHP files and a pair of JSP files: the first file of each pair presents the exercise, the second file ensures the feedback Limits of the QTI Web Pages Generator Does not accept mixed interactions Does not accept adaptive items

The QTI Web Pages Generator IMS-QTI file Initialisations in JSP Initialisations in PHP JSP file for the feedback JSP file of the question PHP file for the feedback PHP file of the question

The QTI Web Pages Generator Two executions on the Web of the same template: 17/04/2017

QTI Metadata Editor With this editor, teachers express: usual LOM metadata (title, author…) educational metadata IMS-QTI metadata (itemTemplate, interactionType, feedbackType, solutionAvailable...) the maximal score of an exercise (to express conditions in an assessmentTest)

Indexing exercise templates A system of classification is created by adding to the taxonomy of the domain a graph of competencies and sub-competencies associated with levels of difficulty This complete system is implemented via a database Teachers use a Web interface to reference the exercise templates in the database, using the metadata associated with the templates

The QTI Test Editor For creating IMS-QTI 2.1 tests by: defining parts, sections, subsections selecting the exercise templates in the database defining in a section a weighting of the exercise scores defining preconditions and branchrules defining feedbacks Generates the IMS-QTI 2.1 file of the assessmentTest

The QTI Test Editor Structure of the test Selection of items from the database

The Test Generator Takes as input an IMS-QTI 2.1 file of a test Generates a PHP file corresponding to the IMS-QTI test, according to the preconditions and branchrules On the Web server, the PHP file guides the learner in regard to his/her results
