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 realization
according to student’ s learning interests, needs and goals

Attaining quality education for all:A UNESCO perspective

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

PLE types - overview
From a pedagogical perspective

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
APLE
Agent-based - integrated services of multiple personal agents for information search/ retrieval

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)
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
Components of APLE:
Profile for adaptable
Learning (PAL): to create
and store learner profiles
Learning Object Tutor
Tools Interface (LOTTI) :
to create adaptable LO
Transformation,
Augmentation and
Substitution Service:
Method to support the
adaptations based on
standards for
interoperability

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

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

3D TechnologiesVRML (Virtual Reality Modeling Language) - old
International Standard ISO/IEC 14772-1:1997
