Virtual Worlds for e-Learning
more dimensions than physical environments more social
than social network softwarenuanced ways (able to show slight difference that may be difficult to notice but are fairly importantmore engaging than physical classrooms Slide3
Approaches
Virtual classrooms, e.g.Second life, VirtualPREX – Providing Virtual Professional Experience for Pre-Service Teachers Fantasy worlds, e.g.
Virtual SingapuraSlide4
Problems
Knowledge and Intelligence Serious games, simulations Usability
Pedagogical valueComplexity of game functions and pedagogy functions. Assigning a gameEducational resource/user managementScenario generationScore-keeping Providing hintsInteractiveness and immersionRealistic, engaging, and immersivemodeling the virtual students and virtual audience which are implemented as NPCs or bots. Adaptivity and personalizationKeeping track of individual interests, preferences, motivations, and goals of the human participants (i.e., learners) and building user/student models. Slide5

Quiz Games in Classrooms
In classrooms, teachers usually use quiz games to create some interesting activities. The purposes of Quiz Games for the classesGood for reviewing and reinforcing previously taught material
Good for warming up or ending lesson on a highA quiz encapsulates the basic unit of conversation Slide7
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 agentSlide8
Purpose of the Project
Build QuizMASter
a virtual world based educational application that mimics a quiz game in classrooms.To build engaging, affectionate, and effective pedagogical agents which is the virtual host in QuizMASter.Team members:Adien Dubbelboer (FHSS)Steve Leung (FST)Sandeep Virwaney (BSc CIS)AJ Armstrong (NAIT, MSc IS)Sima

Open Wonderland Architecture Slide10
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. Slide11
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 Slide12
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. Slide13
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 Slide14

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 goalsEnhancement of TSI featuresMorphing (how accurate of the morphed features is)Sensory abilitiesThere a lot of senses we can mimicSituational contextsThere a lot of situational information we can processModeling of contestantsAgents intelligence: agent learningMulti-agent intelligenceEmerging behaviour of pedagogical agent in quizzes feedback generation.
