Outline
  • Introduction
  • The problem statement
  • The proposed solution
  • Learning Object Context Ontologies (LOCO)
  • The LOCO-Cite ontology
  • An application example LOCO-Analyst
  • Mixed Initiative Coding Environment (MICE)
  • Extending LOCO-Cite to meet the requirements of
    MICE
  • The LOCO-Cite extensions
  • Final Remarks

3
The problem statement
  • Online educators need appropriate and reliable
    feedback about the students usage of the
    learning materials
  • Such a feedback is quintessential for adaptation
    of the learning content
  • Learning Management Systems have only limited
    ability for feedback provision they provide
    only
  • simple statistics about the tools the students
    have used
  • low level interactions with learning content
    (e.g. page views)
  • Therefore, teachers lack consequential awareness
    of what their students are working on and how
    satisfied they are with the content

4
The problem statement
  • Timely and up-to-the-point feedback is also very
    relevant for learners
  • In certain learning domains such a feedback is
    even a condition sine qua non for successful
    learning
  • e.g. when learning to program
  • Our goal is to provide
  • online educators with useful and reliable
    feedback about the students online activities
    and their usage of the learning content
  • learners with feedback on how to regulate their
    learning activities

5
The proposed solution
  • We claim that
  • Semantic Web technologies can improve the current
    state-of-the-art in generating feedback in online
    learning environments
  • Ontologies can interrelate information about
    learning objects, learning activities and
    learners captured from various educational
    systems tools
  • Semantic annotation (based on domain ontologies)
    as a mean of relating different kinds of learning
    artifacts (e.g., lessons, tests, chat messages)
  • Rules and reasoning as means for generating
    feedback out of the available (semantic) data

6
The LOCO framework
  • Based on the notion of Learning Object Context
  • a specific learning situation, determined by the
    learning activity, the learning content, and the
    learner(s) involved
  • aimed at capturing diverse kinds of learning
    situations (i.e., contexts) typically occurring
    in modern e-Learning environments
  • Initially aimed at facilitating reusability of
    learning objects and learning designs, later
    extended to also provide support for personalized
    learning
  • Integrates different kinds of learning related
    ontologies
  • a user model ontology, an ontology of learning
    design, a content structure ontology, domain
    ontologies
  • Flexible design (modular architecture) gt easily
    extensible

7
The LOCO-Cite Ontology
8
An Application Example LOCO-Analyst
  • Aims at helping teachers rethink the quality of
    the learning content and learning design of the
    courses they teach
  • Provides teachers with feedback about
  • the learning activities their students performed
    and/or participated in
  • the usage of the deployed learning content
  • the peculiarities of the interactions among
    members of the online learning community.
  • Feedback provision is based on
  • Semantic representation of usage tracking data
  • Semantic annotation of learning artifacts
  • Simple rules for feedback generation

10
Extending LOCO-Cite to Meet the Requirements of
MICE
  • MICE
  • a modeling and reasoning framework aimed at
    assisting student programmers when learning to
    program using an IDE
  • monitors and captures students interactions with
    different learning tools in order to provide them
    with relevant and timely feedback
  • currently integrates the following systems
    tools
  • The BlueJ IDE
  • The gStudy Learning Kit
  • The iHelp Courses LCMS

11
Extending LOCO-Cite to Meet the Requirements of
MICE
  • MICE needs to recognize and respond to the events
    initiated by the learner
  • The integrated tools need to track students
    interactions and capture events
  • The LOCO-Cite ontology was extended with
    different kinds of events specific for the tools
    that MICE integrates
  • Two extensions
  • The BlueJ extension
  • The gStudy extension

Concluding Remarks
  • Summary
  • The LOCO-Cite ontology defines the notion of
    learning object context by abstracting the most
    relevant concepts from a number of e-Learning
    systems usage tracking data
  • LOCO-Analyst demonstrates how data about various
    learning activities can be integrated to provide
    meaningful feedback for teachers
  • MICE (with extended LOCO-Cite) captures learners
    activities when studying programming languages to
    assist them in their learning
  • Future Work
  • Improve the reasoning over the learning context
    data
  • Research potentials of the framework for
    improving semantic social networking
  • Using Semantic Web Services for on demand
    composition of personalized feedback
