cetis Centre for Educational Technology Interoperability Standards Why Learning Technology Standards? Why IMS? a Discussion Bill Olivier Technical Director, c etis
Following: Some slides actually used in the Session
Where IMS fits in - the others Early on: • AICC (Aircraft Industries CBT Committee) – Problem: Airplanes need maintenance – need many reliably-trained technicians, worldwide – need CBT to help with training • BUT – Airplanes last for 20 years – Computer platforms for 5 (at most) – How to avoid multiple, costly, re-implementations • AICC Specifications – Content sequencing & delivery oriented – Multiple choice testing – CDs, stand-alone PC & isolated learner model
Where IMS fits in - the others • Europe: ARIADNE Project – CE funded project – Large Consortium of University & Industrial Partners – Content & Metadata focused – By ‘ 98 had produced a Metadata specification – Initially hostile to IMS – Signed an Mo. U with IMS to collaborate on Metadata – Both IMS & ARIADNE built on Dublin Core • about 2/3 rds of their extensions cross-mapped • worked to harmonise their specifications
Where IMS fits in - the others • ADLnet (Advanced Distributed Learning Network) – US Dept of Defense initiative – Agreed early (‘ 97) to work with IMS – But narrower focus than IMS (web content delivery) – Impatient with slow rate of progress in IMS 98 -99 – Invited specific companies to define a closed spec – Built on AICC & IMS Content ideas – Produced SCORM v 1. 0 Jan 2000; v 1. 1 Jan 2001 – (Shareable Courseware Object Reference Model) – roughly: AICC for the Web – Web Content, Browser and isolated learner model
- and IMS • IMS - (Not Instructional Management Systems!) – Set up in late ‘ 97 by US universities’ EDUCAUSE – But involved Vendors, US Gov. and non-US bodies – JISC joined in May ‘ 98 on behalf of all UK HE - and now FE - institutions – Early on inherited work of other Groups on Metadata – Look at IMS in more detail later
Then the European Mo. U • PROMETEUS & CEN/ISSS WS-LT – Partially a European response to IMS – Set up at ministerial level in Council of Europe • PROMETEUS – Gather cross-sectoral views – Formulate requirements for specifications – Feed these to CEN/ISSS WS-LT – Trial Projects, Evaluate, Best Practice, Disseminate • CEN/ISSS WS-LT – European Centre for Standards/Information Society… – Working Group has recently put forward a report – Recommendations made to the CE

Formal Standards ISO SC 36 • In Novemeber ’ 99, ISO/IEC, launched new sub-committee – Title: ISO/IEC JTC 1/SC 36 -- Learning Technology – Scope: Standardization in the area of information technologies that support automation for learners, learning institutions, and learning resources – Excluded: The SC shall not create standards or technical reports that define educational standards, cultural conventions, learning objectives, or specific learning content • IEEE LTSC has a ‘formal liaison‘ with SC 36 – recognised as a contributing, but non-voting, body. • CEN/ISSS LT will also form a formal liaison
Formal Standards ISO SC 36 Proposed 4 Preliminary Work Items (PWI) : – Architecture – Metadata – Glossary – Collaborative Learning Technologies
How Initiatives Relate - in theory ISO IEEE Formal Certified Standards CEN/ISSS WS-LT Standards bodies refine existing best practice ‘De Novo’ Specifications IMS produced +ve & -ve experience gained Consortia formed Specifications Implemented ADLnet ARIADNE AICC Need for standards becoming accepted Early Inter -company collaboration

Following: Slides prepared, but not used, in the Session
IMS Approach • Time driven delivery of Specifications • 4 Document Milestones: 1. Scope: what can be done in 6 months? 2. Base: how it is proposed to do it (2 months) 3. Public Draft: closest for trialling (2 months) Trialling of draft takes place, with feedback 4. Final Specification (2 months)
IMS Approach • Consistent format for Final Specifications • 3 parts: 1. Data Model Fields, formats, constraints 2. (Usually) XML Binding DTD (soon XML Schemas) 3. Best Practice Guide Notes for developers and sometimes end users
IMS Specs • • Metadata, building on Dublin Core Enterprise (LMS <---> MIS) Profiles Content – Finding (link to metadata) – Packaging (for shipping between systems) – Launch and Runtime API (with live learners) • Question & Test – Format for Exchanging Questions and Tests – Future: getting Results back from sessions

Issues • • Internet Supported Learning Portable Courses, Portable Content Portable Tests and Questions Description & Search Portable Lifelong Learning Records Class Enrolment and Results Collaborative Learning
Internet Supported Learning • • • Teaching involves a set of complex processes What systems are needed to support these? What Standards are needed to network them? Who Supplies Standards? What if you don’t have standards?
From Functions to System Level Components Cataloguing & Searching Content Authoring Test Authoring Using Content Peer Discussion & Support Standards needed to link & pass information between systems Formative Testing Summative Testing LMS/VLE Repository PDP Course Preparation & Validation Mentor Support Course Catalogue Learning Profile Class Enrolment Student Records
Portable Courses & Content • Why not just use Web Standards? • Is there more to using Content than delivery? • Is there a cultural difference between the approach to learning in the UK the US? • Are we converging? • Will the use of LT bring about uniformity? • Is/Should Learning be Content Driven?
Portable Courses & Content • • • Transporting Learning Objects Aggregation & Disaggregation Using Descriptions Tracking Learners Getting Results back form Session Tests
Portable Tests and Questions • • • Computer Assisted Assessment What is its role? Can it be improved? Must high quality assessment be expensive? Portable tests? Portable results?
Description & Search • Describing Learning Content • What needs to be described? – To Find it? – To Use it? • How should it be described? • Is Metadata the only way? – How have we found learning resources?
Class Enrolment and Results • • • Will Class teaching continue online? What is needed? Linking Academic to Administrative systems Where is the boundary? All ‘Administration’? Negotiating Learning: – Learner – Mentor – Administrator
Lifelong Learning Records • • • Multiple Learning Institutions What should pass between them? Information: Learner’s or Institutions? Control? Will Employers demand it, if it is there? What Levels of detail? Who For?
Collaborative Learning • • Is Internet Learning still based on CDs? Can we harness Internet communication? What kinds of Collaborative Learning? What information is needed? – Groups, Members, Identity, Role, Location, Access, • What functionality is needed? – Messaging (person 2 person & system 2 system), Presence, Shared/Distributed Authoring
