Affective Teachable Agent in VLE: A Goal Oriented Approach.
ABSTRACT Teachable agent is a type of pedagogical agent which instantiates Learning-by-Teaching theory through simulating a "naive" learner in order to motivate students to teach it. This paper discusses existing teachable agent systems and proposes an affective teachable agent based on goal oriented modeling in Virtual Learning Environment (VLE). The proposed agent is more initiative and believable as it is able to behave according to its own goals accompanied with expressions of emotions. A use case study illustrates the effectiveness of this approach.
Conference Paper: Authoring Educational Games through Affective Teachable Agent[Show abstract] [Hide abstract]
ABSTRACT: To take the advantage of computer-aided learning, more and more educational researchers realize the importance of encouraging teenagers to learn in their virtual life. To make the design and development of virtual games continuous and smooth, teachers should be involved in the learning content design iteratively. To this end this paper proposes an authoring tool which extends the teachable agent in Virtual Singapora project with authoring capabilities. In this way, not only educators can directly bring their ideas into the game design, but also the game developers can effectively implement the design to realize game scenarios. A preliminary study illustrates the effectiveness of this approach.Advanced Learning Technologies (ICALT), 2012 IEEE 12th International Conference on; 01/2012
Conference Paper: A FCM based approach for emotion prediction in educational game[Show abstract] [Hide abstract]
ABSTRACT: During playing educational game, the emotion of players can be affected by many aspects, for example the play time, the study time, and achievements etc. Player's emotional status is an internal, dynamic and comprehensive factor that is hard to be detected or predicted by system, which may consist of the interestingness to the game, the internal status of player, or the excitement to the score and so on. In order to predict student's emotional status and to simulate relative emotion state transitions during playing game, we propose a novel method, based on Fuzzy Cognitive Maps (FCMs) modeling method. Several experiments and simulations are provided to illustrate the approach and modeling process in this paper. The results show that players'emotion states can be simulated and computed relatively in educational game by the method.2012 7th International Conference on Computing and Convergence Technology (ICCCT 2012), Seoul; 12/2012
Conference Paper: The Design of Persuasive Teachable Agent[Show abstract] [Hide abstract]
ABSTRACT: Teachable agents are pedagogical agents based on the concept of learning-by-teaching. Persuasion theory enhances the capabilities of teachable agents by influencing positive attitude change in learners. This paper proposes Persuasive Teachable Agent (PTA) that enables the selection of persuasive strategies based on persuasion theory to improve learning attitudes. In a preliminary study involving PTA, learners were observed to display increased interest in engaging in learning activities with the teachable agent.Advanced Learning Technologies (ICALT), 2013 IEEE 13th International Conference on; 01/2013
