  1. Open Wonderland and Multiagent Virtual Learning Environments Oscar Lin Steve Leung School of Computing and Information SystemsFaculty of Science and Technology Athabasca University, Canada January 13, 2012

  2. Virtual Worlds for e-Learning • more dimensions than physical environments • more social than social network software • nuanced ways (able to show slight difference that may be difficult to notice but are fairly important • more engaging than physical classrooms

  3. Approaches • Virtual classrooms, e.g. • Second life, VirtualPREX – Providing Virtual Professional Experience for Pre-Service Teachers • Fantasy worlds, e.g. • Virtual Singapura

  4. Problems • Knowledge and Intelligence • Serious games, simulations • Usability • Pedagogical value • Complexity of game functions and pedagogy functions. • Assigning a game • Educational resource/user management • Scenario generation • Score-keeping • Providing hints • Interactiveness and immersion • Realistic, engaging, and immersive • modeling the virtual students and virtual audience which are implemented as NPCs or bots. • Adaptivity and personalization • Keeping track of individual interests, preferences, motivations, and goals of the human participants (i.e., learners) and building user/student models.

  5. Intelligent Virtual Worlds for e-Learning • Desirable features • Smart • Engaging • Effective • Usable • Agent technology • Sensory ability • Reasoning capability • Social ability • Roles of the agents • Functional modules • Non-player characters (NPCs) • Personal agents • Challenges • User modeling • Decision making • Coordination

  6. Quiz Games in Classrooms • In classrooms, teachers usually use quiz games to create some interesting activities. • The purposes of Quiz Games for the classes • Good for reviewing and reinforcing previously taught material • Good for warming up or ending lesson on a high • A quiz encapsulates the basic unit of conversation

  7. Quiz Master • Quiz master • A TV game show, where a small group of contestants compete by answering questions presented by the game show host. Host - Pedagogical agent

  8. Purpose of the Project • Build QuizMASter • a virtual world based educational application that mimics a quiz game in classrooms. • To build engaging, affectionate, and effectivepedagogical agents which is the virtual host in QuizMASter. • Team members: • AdienDubbelboer (FHSS) • Steve Leung (FST) • SandeepVirwaney (BSc CIS) • AJ Armstrong (NAIT, MSc IS) • SimaShabani (MSc IS) • SteeveLeberge (MSc IS) • Mike Proctor (MSc IS) • Martin Weng (visiting PhD student, Taiwan) • Bob Heller (FHSS) • Oscar Lin (FST)

  9. Open Wonderland Architecture

  10. Agents Architecture • Agents are encapsulated computer systems that are designed to behave flexibly and somewhat autonomously to achieve some goal(s). • Agents are situated in some environment and have some autonomy and capabilities to observe that environment. • They can communicate those observations to other agents. This makes them particularly suited to distributed environments. • Within the distributed environment, the Multi-Agent System (MAS) can be designed using one or more architectures. • The autonomous nature of agents implies that the architecture can even develop dynamically at run-time.

  11. Architecture (1) • As an initial step, we integrated Open Wonderland and JADE through the starting of a JADE server separate from Open Wonderland • Jeanne and Lin, 2011

  12. Architecture (2) • Add a Jason module to Open Wonderland that takes an NPC and controls its movement in the environment. • The NPC runs on the Open Wonderland server and pulls an AgentSpeak() asl file from the file system, sets up its belief system and goals, and then runs. • The Open Wonderland module system makes it simple to extend Open Wonderland to include the framework and any other functionality that is required.

  13. CArtAgO-based Architecture (3) • Common ARTifact infrastructure for AGents Open environments • A general purpose framework that makes it possible to program and execute virtual environments for multi-agent systems. • Based on the Agents & Artifacts (A&A) meta-model for modeling and designing multi-agent systems. • Enables customization of the rendering of visible artifacts for different clients

  14. Scenario • Participants • Contestants (4~6) • The host • The Audience • Subject • ENGL 255 • Process of a QuizMASter session • The host greets the contestants • The audience will be cheering for and looking at all the contestants simultaneously. • Questions are displayed. • Contestants will answer the questions. Scores will be kept. Hints will be provided if needed. • Video: • http://oscar.athabascau.ca/QuizMAster_Lin.avi

  15. Future Work • Proofs: • We are planning for an experiment to test the effectiveness of the platform. • Comparison of TSI enhanced approach and non-TSI enhanced approach • Measurement of the effectiveness to achieve the learning goals • Enhancement of TSI features • Morphing (how accurate of the morphed features is) • Sensory abilities • There a lot of senses we can mimic • Situational contexts • There a lot of situational information we can process • Modeling of contestants • Agents intelligence: agent learning • Multi-agent intelligence • Emerging behaviour of pedagogical agent in quizzes feedback generation.
