Today more and more learning technologies are developed in the virtual environment with intelligent agents to promote students' learning experience and efficiency. Teachable agent is a kind of pedagogical agent that promotes the students' learning through teaching it with concept maps e.g. Betty's Brain. However, the knowledge representation with concept map may be insufficient for a complex knowledge structure, and there will be a limited number of quizzes derived from the concept map. As a result, the teachable agent is taught with limited knowledge.
