Outline

• Introduction• Ubiquitous Learning Context?

• m-LOCO: An Ontological Framework– Delivery Media : Mobile Ontology– Socially enhanced Pedagogy

• Context Capturing in m-LOCO• Usage Scenarios• Summary and Future Study



Introduction

• E-learning environments :– anytime anywhere– personalization :learner-centered

• Rapid growth of usage of mobile technologies in everyday life spontaneous and short study

phases?• E.g. repetition/test preparation/looking up

details



Introduction

Context-aware learning systems– personalization :

• learner-centered + • environmental factors (e.g. location, time of

the day, delivery media)

• Representation Method: Ontologies• Goal: capturing and usage of

contextual info in context-aware learning environments

• Introduction• Ubiquitous Learning Context ?

• m-LOCO:An Ontology-Based Framework

– Delivery Media : Mobile Ontology– Socially-enhanced Pedagogy




Ubiquitous Learning Context?

• Context = situational information– any info to characterize the situation of

an entity relevant to user--application interaction

• Different application domains ~ different needs and requirements different interpretations of

“context”



Ubiquitous Learning Context ?

mobile learning context = learning context captured with regards to its delivery medium, i.e., the mobile devices.

Learning context = learners +LOs + pedagocial approach

m-LOCO

• Our proposed framework : built on top of an existing ontology-based model, LOCO

Delivery Media: Mobile Ontology

• New devices ~ new capabilities/features new vocabularies ontologies

Context Capturing

• a LO repository + a context repository each LO in LO repository ~ context data

in m-LOCO based repository of LOC

• How to capture this context-related data?• LO selection from the LO repository by

learners• System intelligently suggests and delivers

LOs to learners gather and store all related contextual data

in LOC Repository.



Outline






Usage Scenarios : Q1

• utilize the already available context data in m-LOCO repository




• pair a learner during each activity with peers who are directly/indirectly linked to her in her social connections and,– are performing the same activity

(e.g. performance) – in the same subject domain




• learner is asking for assistance/help for a specific topic during an activity

• enhancing social collaboration ?• refer the learner to those peers in

her social links– whose level of skill makes them

eligible to temporarily play the role of an assistant

– in that subject domain



Outline






Summary and Future Work

• To realize the requirements of ubiquitous learning contexts

m-LOCO

• :an ontological mobile learning framework

• :enhances an already existing ontological framework with 2 ontological extensions



Summary and Future Work

• Further investigating of the implementation of this approach and its integration into an operational learning environment.

• Evaluating the effectiveness of the proposed framework
