WEB 2.0: Emerging Paradigm
Personal Learning Environment
• Definition (M. A. Chatti)- A PLE is characterized by the freeform use of a set of
lightweight services and tools (Web 2.0) that belong to and are controlled by individual learners.
• Built by the learner for a specific & personal learning goal- Mashing up the services that will support best the
goal
- No institutional drive or control
page 13

WEB 2.0: Emerging Paradigm
Personal Learning Environment
• Fit well with socio-constructivist learning approaches - Foster collaborative knowledge sharing and building
and reflective practices in a social context
- Foster self-regulated learning sequences by student and discursive argumentation and communication with peer

Mobile, Pervasive, Ubiquitous Learning
A first definition
• Learning with portable technology: PDA, smartphones, PSP, PDA phones, mobile phones, Ipods, Iphones, MP3 players, labtop, UMPC, etc. everytime, everywhere.

Mobile, Pervasive, Ubiquitous Learning
Mobile Computing• Mobile computing: increasing our capability to
physically move computing services with us.
• The computing device cannot seamlessly and flexibly obtain information about the context in which the computing takes place and adjust it accordingly.
Pervasive Computing• Capability to obtain information from the
environment in which it is embedded and use it to dynamically build models of computing.
• Acquisition /management of context models and adaptations

Ubiquitous Computing
• Integrating large-scale mobility with pervasive computing features
Features of mobile, pervasive, ubiquitous
computing belong to those of mobile,
pervasive, ubiquitous learning

ISC Conference 2011 Futures Learning Landscapes
Mobile, Pervasive, Ubiquitous Learning
Bomsdorf 2005- « Ubiquitous learning is the next step in
performing e-learning and by some groups it is expected to lead to an educational paradigm shift, or at least, to new ways of learning. The potential of ubiquitous learning results from the enhanced possibilities of accessing learning content and computer-supported collaborative learning environments at the right time, at the right place, and in the right form. Furthermore, it enables seamless combination of virtual environments and physical spaces ».

ISC Conference 2011 Futures Learning Landscapes
Mobile, Pervasive, Ubiquitous Learning
(Hundebol and Helms 2006)
- « Pervasive learning environment is a context (or state) for mediating learning in a physical environment enriched with additional site-specific and situation dependent elements – be it plain data, graphics, information -, knowledge -, and learning objects, or, ultimately, audio-visually enhanced virtual layers“.
page 22
ISC Conference 2011 Futures Learning Landscapes
Mobile, Pervasive, Ubiquitous Learning
Mobility• Portable Technologies
• Spatial Mobility - Learners moving between different learning settings
• Tool and Thematic Mobility- Learners alternating between different tools and
topics
• Temporal Mobility- Learning is cumulative, current learning builds
on previous learning and are the basis for future learning. page 23
ISC Conference 2011 Futures Learning Landscapes
Mobile, Pervasive, Ubiquitous Learning
Social Community
• Learning is a social process which links learners to communities, people and situations
• Learners are not taught by one teacher, but rather by a community
• Collaborative learning - Learning happens in collaboration between
people and technology
page 24
ISC Conference 2011 Futures Learning Landscapes
Mobile, Pervasive, Ubiquitous Learning
Enable learning activities difficult before,
sometimes impossible
• Learning may occur in location and time which are significant and relevant for learners
• Learning occurs in the context of activities involving an authentic task or problem, a location, a time, an environment, a social community, etc.
• Learning in context and across contexts

Convergence
ISC Conference 2011 Futures Learning Landscapes
Convergence
A global, distributed and open architecture perspective
• Composed of social web environments, institutional learning environments and personal learning environments exposing, sharing, and connecting data on the Web.
page 38
ISC Conference 2011 Futures Learning Landscapes
Convergence
Reuse, analyze and manage content across web application sources
Monitor and analyze user activities and content production, to get user traces and to provide guidance and advices according to user activities and needs
Combination of all these resources and techniques allow getting contextual data from web environments and sensors

Inquiry Based Science Teaching: IBST V. 1
IBST features
• Authentic and problem-based learning activities which are ill-
defined and have several answers
• A certain amount of experimental procedures, experiments and
activities involving practical experience of equipment and
including searching for information;
• Self regulated learning sequences where student autonomy is
emphasized;
• Discursive argumentation and communication with peers
("talking science").

The complete problem
• Problem 1: understand the industrial landscape in the area of the bridge (Brest is a shipbuilding arsenal for the Navy).
• Problem 2: understand what is the historical and technological method of problem solving that led to the construction of the swinging bridge.
• Problem 3: understand the rotating mechanism of the swinging

Historical reading and understanding of an
industrial landscape (scenario stage 4)
• Photograph all elements of the current landscape with
historical aspects about cranes and bridges of the arsenal,
• Locate the different elements on a current map of Brest,
• Identify and photograph the actual bridges and cranes linked
existing bridges and cranes from previous: what continuities ?
What ruptures?
• Store and publish information on the corresponding tools.

Models enable us to have common vocabularies to
ensure exchange, reuse and sharing of resources
at semantic level (Ontologies)
• A context model- including a user model, a scenario model
• A domain model
• A resource model (a metadata schema)
• A Recommendation model (adaptation model),
page 54
ISC Conference 2011 Futures Learning Landscapes
Inquiry Based Science Teaching: IBST V. 2
Some metadata can be generated automatically
(sometimes on the fly)
• from the tool databases according to common vocabularies like - Dublin Core, SKOS, SIOC, FOAF, OPO, etc.
Most of these vocabularies are lightweight
ontologies that can fit well database schemas
