Overview
Overview

  • When might we want to use LD+QTI together?

  • How do CP+LD+QTIv1.x fit together today?

  • Are there any issues?

  • LD and QTIv2


When might we want to use ld qti together
When might we want to use LD+QTI together?

  • Quite often

  • IMS Learning Design is used to model units of learning

    • A unit of learning (UoL) is any delimited piece of education or training, such as a course, a module, a lesson, etc.

    • more than just a collection of ordered resources to learn

    • activities, assessments, services and support facilities provided by teachers, trainers and other staff members.

  • Model who does what, when, with whom and using which learning objects and services

Using ld qti together
Using LD+QTI together

  • When are tests/assessments used in learning designs?

  • Formative and summative assessment

    • “summative assessment summarises the quality and characteristics of the student.

    • formative assessment relates to students’ learning processes, helping to guide them in their studies, providing feedback on areas of learning requiring further work, ….”From “The Handbook for Economics Lecturers”


Some ld qti learning scenarios 1
Some LD+QTI learning scenarios (1)

  • Single learner scenarios:

    • Want to check the learner’s level of understanding before sending him/her down a particular learning path (intake assessment);

    • Want to check whether a concept has been learned before allowing the learner to progress;

    • Want to provide a high level of feedback in a module to keep motivation high;

    • Want to end a course with an examination;


Some ld qti learning scenarios 2
Some LD+QTI learning scenarios (2)

  • Multi learner scenarios:

    • Want to have individuals’ answers be revealed to a group to promote discussion and learning;

    • Want to arrange for peer assessment;

    • Want to divide a set of students into several groups of more-or-less equally able students;

    • Want to divide a group of students into groups with individuals of differing levels of ability;

    • Want to give the best/worst performer in a group a particular role in a learning design;



How was this type of thing done in eml
How was this type of thing done in EML?

  • The EML DTD provides interactions

  • An EML-aware player takes EML content perhaps including interactions and plays it. So ….



Moving from eml to ims ld
Moving from EML to IMS LD

  • EML complete/monolithic

  • Moving to IMS LD meant taking other IMS specs into account—integrating LD and CP, stripping out the content model, interaction types etc

  • Moving from EML to IMS LD is really moving from EML to IMS CP+MD+LD+QTI+….+XHTML


Ld and cp 1
LD and CP (1)

  • To create a UoL, IMS Learning Design is integrated with an IMS Content Package as another kind of organization within the <organizations> element.

  • An IMS content package is called a 'Unit of learning' if and only if it includes a valid IMS learning-design element in the organizations part of the package's manifest.



Orchestrating learning with ld
Orchestrating learning with LD

  • Learning Design orchestratesthe availability of variousactivities & their resources,including assessments;

  • In certain conditions, particularactions are taken;

  • Properties available forgetting and setting;

  • Expression language usedto express conditions




But where is p intake score set
But where is P-intake-score set?

  • The actual intake test would be QTI content

  • Maybe have an LD+QTI aware engine

  • More likely an LD-aware engine uses a QTI-engine

  • Need QTI and LD to ‘share’ P-intake-score

    • Declared by both

    • Set by QTI engine

    • Read by LD engine



Where does the qti go in the uol
Where does the QTI go in the UoL?

  • Either in the environment/learning-object as a separate schema. Tests can then be connected to learning-activities.

  • Or in IMS Content Package (specific resource types?) as separate files/links


Are there any issues
Are there any issues?

  • <imsqti:decvar varname="P-intake-score" … >

    • String, 256 chars

    • Enumerated, String, Integer, Decimal, Scientific, Boolean, Enumerated, Set

  • <imsld:locpers-property identifier="P-intake-score">

    • XML ID

    • boolean, integer, real, string, datetime, duration, text, file, uri and other.


Ld and qtiv2
LD and QTIv2

  • OUNL participating in QTIv2

    • to create a new version of the QTI specification to address relevant issues deferred from v1.0,

    • to describe best practice for putting QTI into content packages

    • to describe bindings for QTI outcomes to Learning Design properties, to Simple Sequencing objectives, and into the CMI datamodel.

  • Best practices

    • Using LD and QTI together

    • Variable naming and typing

    • Pre-processing error checking recommendations for content packages?
