Technology succession and open source VLEs:  Technology succession and open source VLEs Martin Weller Outline:  Outline Technology uptake Current VLE usage Technology Succession Case studies OS as reasonable compromise VLE 2.0 Technology uptake:  Technology uptake Technology uptake:  Technology uptake Lead users - flexibility, richness, and a strong theoretical underpinning Conventional users - robustness, ease of use and practicality What’s wrong with VLEs?:  What’s wrong with VLEs? They are content focused They have no strong pedagogy They are based around a teacher-classroom model They combine a number of average tools, but not the best ones They do not feature a particular tool They operate on a lowest common denominator approach They do not meet the needs of different subject areas It is difficult to exchange content between them, despite claims to interoperability Current state of play:  Current state of play OECD/OBHE 2004 survey in 13 countries All had VLE 37% have institution-wide VLE 90% expect to have single VLE in next 5 years 52% use commercial system Rest use combination of in-house and open source No institution had just OS 31% had portal 6.6% had CMS Changing times:  Changing times Nearly all institutions had moved to an institution-wide system. Few institutions operated an in-house solution. The VLEs will be divided equally between commercial and open source solutions. Specialization and localization will occur through the use of services. Plant succession:  Plant succession Technology succession:  Technology succession 'technological environments are not merely passive containers of people but are active processes that reshape people and other technologies alike' (McLuhan 1962) Case studies:  Case studies UKOU – had lots of components, opted for Moodle SUNY – uPortal + LAMS Deakin – many installations, WebCT NZ – Moodle A flexibility continuum:  A flexibility continuum Commercial VLE SOA OS Standards SAKAI OS as reasonable compromise:  OS as reasonable compromise Gain: Functionality Time Community Profile Flexibility Technical consensus Lose: Some flexibility Some control Conventional users - sufficiently robust, not a research tool. Lead users - flexible, adaptable to the needs of any particular institution, Can act as the ‘backbone’ of a service oriented solution. Web 2.0:  Web 2.0 Both an approach and a set of technologies Web as platform Harnessing collective intelligence Evolutionary development Lightweight programming models This time, though, the clash isn't between a platform and an application, but between two platforms, each with a radically different business model: On the one side, a single software provider, whose massive installed base and tightly integrated operating system and APIs give control over the programming paradigm; on the other, a system without an owner, tied together by a set of protocols, open standards and agreements for cooperation 'users add value and the technology or site needs to be set up so that it encourages participation' Users must be treated as co-developers, … The open source dictum, 'release early and release often' in fact has morphed into an even more radical position, 'the perpetual beta,' in which the product is developed in the open, with new features slipstreamed in on a monthly, weekly, or even daily basis…. VLE 2.0:  VLE 2.0 How would a VLE 2.0 be constructed? Service oriented Tools tested and released Standards based Unique configurations Incorporate external tools Localized configurations Personalised What does web 2.0 education feel like? Students as co-creators Reuse Less rigid boundaries Social Contact:  Contact Email: m.j.weller@open.ac.uk Blog: http://edtechie.net Home page: http://iet.open.ac.uk/pp/m.j.weller Book: Virtual Learning Environments, Routledge, Spring 2007
