了解有效的人类导师的策略是发现有效的辅导策略的途径之一。这些策略是根据导师在与学习者互动时采取的行动来描述的。为此，我们在本文中分析了基于对话的专业导师与学生之间的互动。在探索这种基于对话的教程交互模式时存在两个挑战。首先，我们需要将导师和学生的话语映射为行动。为了应对这一挑战，我们依靠语言即行动理论，根据该理论，当我们说某事时，我们就会做某事。第二个挑战是使用客观的学习测量来检测有效的辅导课。为了应对这一挑战，我们将辅导对话与从智能辅导系统获得的学生掌握的前后测量相结合，学生在与人类导师互动之前和之后进行互动。我们展示了我们开发的自动化工具的性能结果，这些工具可以将导师-导师的话语映射到对话行为和对话模式上。我们还报告了导师和学生行为方面最有趣的新模式。这些模式可以帮助我们理解辅导过程和智能辅导系统的开发。
Understanding effective human tutors’ strategies is one approach to discovering effective tutorial strategies. These strategies are described in terms of actions that tutors take while interacting with learners. To this end, we analyze in this paper dialoguebased interactions between professional tutors and tutees. There are two challenges when exploring patterns in such dialoguebased tutorial interactions. First, we need to map utterances, by the tutor and by the tutee, into actions. To address this challenge, we rely on the language-as-action theory according to which when we say something we do something. A second challenge is detecting effective tutorial sessions using objective measurements of learning. To tackle this challenge we align tutorial conversations with preand postmeasures of student mastery obtained from an intelligent tutoring system with which the students interacted before and after interacting with the human tutor. We present performance results of the automated tools that we developed to map tutor-tutee utterances onto dialogue acts and dialogue modes. We also report the most interesting emerging patterns in terms of tutor and tutees’ actions. These patterns could inform our understanding of the tutoring process and the development of intelligent tutoring systems.
