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
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 12
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

Is-it a technological problem?
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 16
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.
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 17
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
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 18
Mobile, Pervasive, Ubiquitous Learning
¢ Ubiquitous Computing • Integrating large-scale mobility with pervasive
computing features
¢ Features of mobile, pervasive, ubiquitous computing belong to those of mobile, pervasive, ubiquitous learning
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 19
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 ».
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 20
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“.
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 21
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.
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 22
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

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

- SPARQL Access Point – Query language + Access protocol
The Web will be
a Tremendous Global Database

Convergence
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.
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 37
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 V. 1
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").
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 40
Inquiry Based Science Teaching: IBST V. 1
¢ 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

Inquiry Based Science Teaching: IBST V. 1
¢ 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.

¢ Three Push modes • Recommend information from Navy museum and
local public records retrieved by other group members or subgroup according to the needed domain concepts identified on the port and/or the current activities
• Recommend and provide information from subgroup visiting the port to other subgroups or group members
• Recommend checking some domain concepts missed by students or subgroups on the port.
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 49
Inquiry Based Science Teaching: IBST V. 2
¢ Pull Mode • A query filters concepts, resources, activities and
persons • Write queries
- On relevant domain concepts like “crane”, “bridge”, etc. according to the current context (activities and localization),
- On retrieved information from other group members or subgroups according to activities and/or localization

¢ 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 peer assessment model • A recommendation model (adaptation model),
Hammam Sousse ISITC 2011 Futures Learning Landscapes page 53
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
