This document discusses the design and development of a three-dimensional personal learning space (PLE). It provides an overview of PLE models and architectures, examines how PLEs can support quality education, and explores using 3D technologies to create personalized learning environments. Specifically, it analyzes the functional and technical aspects of building a 3D PLE, presents examples of using virtual worlds like Second Life for learning, and proposes a vision for a 3D PLE that would allow users to manage learning activities, interact socially, and access multimedia content in a customized 3D space.

6. PLE types - overview From a technical aspect start pages, feed readers, blog, wiki Distributed - combines student-selected tools on one interface Mashup – via widgets, RSS feeds, API PLEF web-based browser and server systems Integrated - web-based learning platform with pre-built tools SAPO Elgg PLEX Client software P2P - every participant takes a portion of other s‘ resources Client software Colloquia Adaptable – method to support the adaptations based on standards for interoperability web-based browser and server systems APLE Agent-based - integrated services of multiple personal agents for information search/ retrieval web-based browser and server systems PABF 3D browser and server systems 3B 3D– 3D technologies to support personal learning needs Second Life Client software Browser Plugin Exit Reality

21. Personal Agent-based Framework Benefits of the framework : • personalized information services with minimal burden on the user • integrated services of multiple personal agents for information search and retrieval • a secure environment that ensures the privacy of personal profiles for registered users Authors: I.B. Crabtree, S.J. Soltysiak, Intelligent Systems Research Group, BT Laboratories, UK

22. Nfomedia – possibilities for PLE Personal site for every registered student

23. 3D World - Definition A 3D virtual world is a computer-based, simulated 3D environment where users are able to interact and socialize with others and experience the environment through their avatars Source: http://www.exitreality.com/3dvirtualworlds.html

24. Why 3D? Motivation: 3D Interactive environments: Visualization in 3D dimension Highly adaptable, user created High level of interactivity Possibilities for self-paced activities Social Interaction through dialogue and collaboration, networking Informal learning opportunities Realization of a wide variety of learning scenarios Support different multimedia formats Greater connectivity and engagement
