Summary

• Overview of Learning Design Process• Existing (some) learning design editors• Some requirements for the IMS LD editor• The new IMS LD editor• Conclusions


Overview of Learning Design Process

Selection of Knowledge Domain, Context/Setting, Objectives,Target Group

Selection/design of suitable Pedagogical Model Select/design Learning Design Model Content Selection and Design Services Selection and Design Integration of Learning Design, Content and

Service Specifications in a Course Package

Outcome: ‘Unit of Learning Package’ that can be transferred and interpreted by computers to deliver the course

Learning Design Editor

Pedagogical strategy definition

Run time: learning design player



What is a pedagogical model ?

• A method that prescribes how a class of learners can achieve a class of learning objectives in a certain context and knowledge domain

• E.g. a method describing: * How adults learn Spanish as a second language * How engineers learn mathematical skills* How to learn the skill to defend verdicts in a law court?



What is a Learning Design?

• An instance of a pedagogical model: a concrete application of a pedagogical model for a specific target group, for specific learning objectives and a specific domain and setting.

• The learning design specifies the specific workflow and content in the learning process:

which role has to performs which activities, using which resources and services in which order, to attain the learning objectives in the best way, taking care of individual differences



The approach:Educational Modelling Language/IMS LD

Basic Idea:

• Develop a ‘language’ to describe the content and processes within courses in a formal, semantic way, so that it is understandable by humans and can be interpreted by computers.

• This description should be independent of any delivery platform => can be deployed in any platform that provides the adequate functionality

IMS LD specification


Existing (some) learning design editors

ReloadCosmos

LAMS

elive



From the analysis of existing editors some highlighted weaknesses:

• Reload: editor for content developers who have some level of technical knowledge. E.g. they must know what a ‘content-package’ is what elements compose the IMS-LD specification.

• Elive LD suite: specialised editor not based on template. Proprietary, difficult to be integrated in any other LMS or digital repository.

• Collage: it allows only the editing of Units of Learning (UoLs) by reusing and customizing best practices, which are formulated as patterns.

• Cosmos: The tool is designed in a way adhering rigidly to IMS-LD. Required a deep knowledge about IMS-LD

• LAMS: learning design editor but not compliant to IMS LD (no interoperability ensured)



Derived requirements for a new IMS Learning Design Editor:

1. Completeness: describe the teaching-learning process in a unit of learning, including references to the digital and non-digital learning objects and services needed during the process. 2. Personalization: describe personalization aspects within a learning design, so that the content and activities within a unit of learning can be adapted based on the preferences, educational needs, business processes and situational circumstances of users. 3. Compatibility: use available standards and specifications where possible. 4. Reusability: identify, isolate, de-contextualize and exchange useful learning artefacts, and to re-use these in other contexts. 5. Easy to use: combine the tree view with graphical representation for the relationships description


Implemented new IMS LD editor

Adopted solution:

1. IMS LD compliancy

2. Use the tree-based model for the fine data entry of IMS LD elements

3. Use the graphical representation to show relationships among parts of LD

4. Use graphical editor to simplify the LD structure definition

Benefits of the new IMS LD editor

• Interoperable, thanks to the IMS LD level A compliancy

• More intuitive, thanks to the graphical editor

• Complete, thanks to the tree-based editor


Weaknesses of the new IMS LD editor

• Still Level A only

• Still too much IMS oriented (e.g. elements names are from the IMS documents)


Conclusions

• New IMS LD level A compliant editor

• Combination of tree and graphical approach to improve usability and sustain the adoption of IMS LD specification

Future works (ongiong):

• IMS LD Level B• Simple Wizard for the initial data entry of mandatory elements• Use more understandable terms in the GUI (and transparently map these terms back to the IMS spec)
