Conclusion
PLE Definition
Virtual Personal Learning Environment (VPLE)
self-managed learning to integrate personalized
information and knowledge to allow social contacts and
communication channels with flexible technical
configuration with different possibilities
for learning scenarios realizationaccording to student’ s learning interests, needs and goals

Attaining quality education
personalized learning ensures that all students meet high
educational standard acquisition of the
knowledge they need to pursue their goals according to their cadences
still a challenge for educators and universities
Self Management
PLE types - overview From a pedagogical perspective
Closed – working with
given scenarios
Open – extendible according learning
scenarios
Non-collaborative – self-performed
activities
Collaborative – collaborate in
learning activities
Controlled – use given resources
Free – no limit in used learning
resources
PLE types - overview From a technical aspectDistributed - combines student-selected tools on one interfaceIntegrated - web-based learning platform with pre-built tools
Mashup – via widgets, RSS feeds, API
3D browser and server systems
web-based browser and server systems

Adaptable – method to support the adaptations based on standards for interoperability Agent-based - integrated services of multiple personal agents for information search/ retrieval3D – 3D technologies to support personal learning needs

Distributed – Personal Learning Environment Framework (PLEF)
PLEF –specially designed for educational purposes http://eiche.informatik.rwth-aachen.de:3333/PLEF/
Distributed - Feed readersFriendFeed: Collect information from several servers: http://friendfeed.com/
Distributed - Feed readers EduFeedr - Standard RSS reader for monitoring and analyzing
learning activities, designed for educational purposes http://en.wikiversity.org/wiki/

Distributed, desktop application: FeedForward Aggregative newsfeeds, photostreams and playlists from general Internet
sources useful for informal learning, and collecting metadata from formal resource collections: http://www.getfeedforward.org/

Integrated - SAPO Campus Architecture
Institutional LMS, PLE is supported, based on the Universal Widget API (UWA) from Netvibes and allows the integration of a large number of widgets from other servers
Authors: C. Santos, L. Pedro, University of Aveiro, Portugal
Integrated - Adaptable personal learning environment (APLE)
Authors: Dr Elaine Pearson ,Voula Gkatzidou, Dr Steve Green), Accessibility Research Centre, University of Teesside
Components of APLE:
- Profile for adaptable Learning (PAL): to createand store learner profiles - Learning Object TutorTools Interface (LOTTI) :to create adaptable LO
- Transformation, Augmentation and Substitution Service: Method to support theadaptations based onstandards for interoperability
• Includes the typical basic features of a standard VLE: Learning activities, email,
timetable, tutor tools, etc
• Students ‘ profiles determine interface, interaction methods, learning level
• Tutors make adaptations on behalf of students
• Enables independent access to learning

Personal Agent-based Framework
Authors: I.B. Crabtree, S.J. Soltysiak, Intelligent Systems Research Group, BT Laboratories, UK
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
Nfomedia – possibilities for PLE
Personal site for every registered student
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
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
