本章讨论了一些设计时遇到的挑战，开发一个对话式教学代理。通过追踪智能教学系统（ITS）中教学代理的历史根源，我们发现了创建一个既有知识又能促进与学习者的社会关系的代理的中心发展。当试图开发这种教学代理时，一些主要的挑战是：i）学习者对代理的知识概况和社会概况的期望，ii）处理学习者参与任务外会话和iii）管理潜在的滥用代理。我们说明了这些挑战和可能的方法来解决它们，参考正在进行的研发项目，并侧重于教学代理的视觉体现和其对话能力的设计。（减）
The chapter discusses some design challenges encountered when developing a conversational pedagogical agent. By tracing the historical roots of pedagogical agents in Intelligent Tutoring Systems (ITS), we discern central developments of creating an agent that is both knowledgeable and fosters a social relationship with the learner. Some main challenges when attempting to develop a pedagogical agent of this kind regard: i) learners’ expectations on the agent’s knowledge profile and social profile, ii) dealing with learners’ engagement in off-task conversation and iii) managing potential abuse of the agent. We illustrate these challenges and possible ways to address them, with reference to an ongoing R&D project, and with a focus on the design of a pedagogical agent’s visual embodiment and of its conversational capacities.
