  1. The 5R Adaptation Framework for Location-Based Mobile Learning Systems Kinshuk, PhD Associate Dean, Faculty of Science & Technology Professor, School of Computing and Information Systems NSERC/iCORE/Xerox/Markin Industrial Research Chair for Adaptivity and Personalization in Informatics Athabasca University, Canadakinshuk@ieee.orghttp://kinshuk.athabascau.ca (jointly with Qing Tan, Xiaokun Zhang and Rory McGreal)

  2. Overall research direction • Individualised learning in increasingly global educational environment • Bridging the gap among different types of learners • Support for: • Mobile and life-long learners • Just-in-time and on-demand learning • Context adaptation

  3. Vision ~ Learning omnipresent and highly contextual ~ So how do we do it?

  4. Adaptivity in ubiquitous learning Extensive modelling of learner’s actions, interactions, “mood”, trends of preferences, skill & knowledge levels, implicit and explicit changes in skill & knowledge levels Real-time monitoring of learner’s location, technology use, and change of situational aspects

  5. Learner awareness • Personalization of learning experience through the dynamic learner modeling • Performance based model • Cognitive trait model • Learning styles

  6. Dynamic learner modeling Mining of historical and real time data for real-time adaptivity • Learning activities • Learning style • Interests & knowledge • Problem solving activities • Learning object/activity usage • Social activities • Learner location • Location related activities

  7. Technology awareness • Personalization of learning experience through the identification of technological functionality • Identifying various device functionality • Dynamically optimize the content to suit the functionality • Display capability, Audio and video capability, Multi-language capability, Memory, Bandwidth, Operation platform

  8. Location awareness • Personalization of learning experience through the use of location modeling • Location based optimal grouping • Location based adaptation of learning content • Location based collaborative creation of authentic content

  9. Location based technologies

  10. Location aware dynamic grouping Location Grouping Mobile Learner’s Address Mobile Learner’s Cellular Data Mobile Learner’s GPS Coordinates Mobile Learner’s Other Location Info Mobile Virtual Campus Mobile Learner’s Learning Profile Mobile Learner’s Learning Style Mobile Learner’s Learning Interests

  11. Location based content creation

  12. Real-life physical objects • Personalization of learning experience as per surrounding environment • Public databases of POIs • QR Codes • Wi-Fi & Bluetooth Access Point identification • Active and Passive RFIDs

  13. Surrounding context • Personalization of learning experience through the use of surrounding context • Identifying specific context-aware knowledge structure among different domains • Identify the learning objective(s) that the learner is really interested in • Propose learning activities to the learner • Lead the learner around the learning environment

  14. 5R Adaptation Framework

  15. Introduction of framework • A conceptual framework for the implementation of Adaptive Mobile Learning systems. • An ontology model of the framework in which the factors of Learner, Location, Time, and Mobile Device are considered in generating Personalized Learning Contents

  16. Introduction of framework (cont. 1) • Challenge of facilitating mobile learning and ensuring learners’ performance: Presenting or generating personalized learning contents and instructions dynamically Dynamic Contents Learning environment and mobile device Mobile Device The context of learning process and instruction Context Aware Appropriately identifying characters of particular learner. Learner Identification

  17. Introduction of framework (cont. 2) The challenge facing the development of location-based adaptive learning applications is the ability to deal with these contexts from Learning Perspective. One of the key strategies is to: identify and normalize context information based on efficient context-aware data fusion. semantic-based context constraints using composable ontology models.

  18. Introduction of framework (cont. 3) The Ontology-based approach: Uses predefined metadata models of the learning contents, learner models, context information of the learning activities, and mobile device, etc. Retrieve structured and unstructured learning materials and generate personalized, just-in-time, and location-aware learning contents or adaptive “filter” that directs mobile learner to access right contents.

  19. Introduction of framework (cont. 4) The First approach: To create semantic learning contents manually. • The Second approach: • To take advantage of pre-existing learning objects. • To develop shareable ontologies, publishing learning objects standard, and reward mobile service system to make the learning objects widely accessible. Our Research Aim: To conduct bottom-up development of the ontology for the personalized learning objectives, learning context information and proposed 5R constraint information.

  20. Introduction of framework (cont. 5) The Third approach: To develop software and knowledge retrieval mechanism that automatically identifies appropriate learning components and extracts structural knowledge from unstructured learning contents. Learning contents are pre-developed and stored in the learning contents repository of the learning management system. Our Research Aim: To build and manipulate adaptive “filter” to direct just-in-time retrieval paths during the mobile learning processes.

  27. Implementation of framework The First layer: Consists of “Location”, “Time”, “Learner”,“Device”, and “LearningContents”, respectively representing the five adaptation inputs. The Second layer: Furtherdescription of information or data of each adaptation input. The ontology scheme, namely, the relationshipsamong the adaptation inputs,which illustrates why the inputs need to be described and how the inputs are interconnected.
