<span style="font-size: 10.0pt; font-family: &quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family: SimSun; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">Intelligent Pedagogical Agents (IPAs) are designed for pedagogical purposes to support learning in 3D virtual learning environments. Several benefits of IPAs have been found adding to support learning effectiveness. Pedagogical agents can be thought of as a central point of interaction between the learner and the learning environment. And hence, the intelligent behavior and functional richness of pedagogical agents have the potential to reward back into increased engagement and learning effectiveness. However, the realization of those agents remains to be a challenge based on intelligent agents in virtual worlds. This paper reports the challenging reasons and most importantly an approach for simplification. A simulation based on BDI agents is introduced opening the road for several extensions and experimentation before implementation of IPAs in a virtual world can take place. The simulation provides a proof-of concept based on three intelligent agents to represent an IPA, a learner, and learning object implemented in JACK and Jadex intelligent agent platforms. To that end, the paper exhibits the difficulties, resolutions, and decisions made when designing and implementing the learning scenario in both domains of the virtual world and the agent-based simulation while comparing the two agent platforms.</span>
Highlights
AND MOTIVATIONLearners in a virtual world enjoy rich visualization, collaboration, and continuous remote availability of learning resources in the environment
Design and implementation of intelligent pedagogical agents based learning in a virtual world has three thrusts of the implementation: the learner avatar aspects, the Intelligent Pedagogical Agents (IPAs) aspects, and converting an object to become learning aware
In regular learning scenario settings, a learner interacts with a learning object conducting a simulation of a device operating the experiment through a control panel that will in turn provide parameters to a simulation to result in displayed output or 3D visualization in the virtual world
Summary
Learners in a virtual world enjoy rich visualization, collaboration, and continuous remote availability of learning resources in the environment. Design and implementation of intelligent pedagogical agents based learning in a virtual world has three thrusts of the implementation: the learner avatar aspects, the IPA aspects, and converting an object to become learning aware. The virtual world environment supporting the IPA operations mandates implementation efforts and experience targeting specific platforms and particular surrounding technologies With those requirements, the realization of IPA in the virtual world faces the following challenges in the pragmatic dimension: 1. The implementation of an IPA imposes requirements of the IPA to be realized in the virtual environment including animation and multi-modal conversation abilities This is in addition to the interaction with complex learning resources that have been designed for the purpose of deployment in the virtual world such as experiments found in [1] and [2].
