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

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

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

Conclusion Analysis of functional and technical
characteristics of 2D PLE is performed Several examples for PLE building are
presented Advantages of 3D worlds are discussed 3D PLE vision is proposed
Future work
Working on prototypes, templates, objects Performing experiments in a learning process
