Using Open Document Format for Interactive Learning Content

Robby RobsonEduworks Corporation

21 Sep, 2006Open Document Format 2Eduworks Corporation

An Old Problem …

Common, standards-based format for interactive learning content

CBT Interchange [See Frank Farance slides from March, 2000]

Tyde says: “The courseware conversion problem actually goes back much further. You can mention that Philip Dodds was talking to them in the early 90s (as was I) about possibly using Kaleida ScriptX as a solution (defunct Apple/IBM technology)”


Why is this important?

REUSABILITY Combine content from multiple sources Reuse content snippets

DURABILITY Update and maintain content over time Re-create content as formats change

PORTABILITY Express same content in different formats Interchange content among multiple systems


XML SCORM Studio

Joint ADL Co-Lab 2006 Prototype

Slides repurposed fromAugust 23, 2006


The Vision

Good content in a minute


The Vision

Good content in a minute that reuses existing content


The Vision

Good content in a minute that reuses existing content from multiple sources


The Vision

Good content in a minute that reuses existing content from multiple sources and conforms to SCORM 2004


To achieve the vision …

Combining and repurposing interactive training content must be as easy as combining and repurposing PowerPoint slides

Working with instructional designs must be visual and simple

Creating SCORM 2004 content must be almost trivial


A SCORM 2004 content design, conversion, aggregation & editing tool

A tool for combining content from multiple sources in different formats into SCORM courseware with a consistent look and feel

A tool for creating, visualizing and reusing complex sequences of modules with pre-tests, post-tests and remediation

Open Source .NET software

XML SCORM Studio …


XML SCORM Studio can be used to … Convert existing interactive content into

SCORM 2004 content Develop new SCORM 2004 courseware

from combinations of existing content Create, store and reuse sequencing and

navigation patterns in SCORM 2004 courseware


Under the Hood:

Content is expressed in XML using OpenDocument format extended by other open standards.

Separates media elements, navigation and styles

Can be rendered as Dynamic HTML (and eventually other formats such as formats for mobile devices.)


XML SCORM Studio supports four basic actions … Apply instructional design templates Convert existing training content to a

standards-based format Edit and combine converted content Export the results as SCORM 2004

DEMO

“Programming today is a race between software engineers stirring to build bigger and better idiot-proof programs, and the universe trying to produce bigger and better idiots. So far, the universe is winning.”


Back to the underlying format

Repurposed from slides presented by Tyde Richards in January, 2006


Requirements for underlying format:(1) Card Deck Metaphor

Requirements for underlying format:(2) Ability to represent non-learning specific content elements

Requirements for underlying format:(3) Ability to share states

Relational Navigationhelp, browse, related content

Requirements for underlying format:(4) Support for navigational links


Candidates Considered

OASIS DITA Readable help documentation Type/specialization & relational browsing

OASIS Open Document Format (ODF) ISO standards track “office document” format Includes several W3C content formats

Rich Internet Application/UI languages Mozilla XUL, Macromedia MXML, Microsoft XAML Associated with particular platforms

W3C Compound Document WG Issues of integrating XML content specifications


Reasons for Choosing Open Document Format Open specification (now an ISO/IEC

Standard) Incorporates W3C specifications Significant adoption and open source tools

available (Open Office, IBM Workplace, AODL – now Google & MS Office)

Could be extended to include other XML schema (e.g. QTI)

Specifically used “Presentation” version, called ODP

ODP “primitive”

Extended (e.g. “learning”)


All Components Have

ODP Content

ComponentCommon Properties• Height, Width• XY coordinate• Type

Common Events• DOM event• JavaScript Handlers• Use optional

Editor• means to visualize ODP component• means to edit an ODP component

Delivery Format Generator• XML to delivery format• Default DHTML

The component approach also supports a modular approach to implementing content converters


Example (QTI in ODP)


ODP Content Components

Locations contain components

Components share common capabilities and are cleanly encapsulated

Basic components directly taken from ODP

Extended components may be based on ODP or on other schemata

TextBox

ODP Primitive Extended

Location may contain:


Way forward (Tyde says) Set up an ODF Content – XML SCORM Studio

activity (e.g. on www.adlcommunity.net) Develop an ODF profile for SCORM content

A profile not a new specification. Basic profile of the ISO/IEC ODF standard for SCO content

that integrates the CMI runtime, possibly LOM, and a subset of QTI

Separate activity to look at S1000D outside the initial scope Activity for discussion related to the open source XML

SCORM Studio tool Links to Source Forge project

Goal: Have profile & open source tool by March 2007 ADL SC36 event

Note: Interest from ADL, IMS, OASIS and others
