智能辅导系统(ITSS)为学生在复杂的问题解决活动中提供循序渐进的指导，已被证明在一系列领域提高了学生的学习能力。然而，它们往往很难建造。我们的项目调查是否可以简化ITS的创作过程，同时保持使其有效的特征，并保持支持大规模导师开发的能力。具体地说，我们的项目测试了基于演示编程技术(在先前的研究中开发)的创作工具是否可以支持大规模、真实世界的导师的开发。我们正在创建一个开放访问的网站，名为MathTutor(http://webmathtutor.org)，)，在这个网站上，中学生可以在ITS的逐步指导下解决数学问题。Mathtutor网站提供了跟踪教师的例子，这是一种新型的ITS，它是通过“演示”构建的，没有编程，使用的是认知辅导创作工具(CTAT)。该项目的主要贡献将是，它代表了通过演示编程进行大规模导师创作的严格测试。第二个贡献将是，它将测试一个开放获取网站(即，一个广泛和免费提供的网站)是否能够吸引和维持用户的兴趣和大规模学习。
Intelligent tutoring systems (ITSs), which provide step-by-step guidance to students in complex problem-solving activities, have been shown to enhance student learning in a range of domains. However, they tend to be difficult to build. Our project investigates whether the process of authoring an ITS can be simplified, while at the same time maintaining the characteristics that make ITS effective, and also maintaining the ability to support large-scale tutor development. Specifically, our project tests whether authoring tools based on programming-by-demonstration techniques (developed in prior research) can support the development of a large-scale, real-world tutor. We are creating an open-access Web site, called Mathtutor (http://webmathtutor.org), where middle school students can solve math problems with step-by-step guidance from ITS. The Mathtutor site fields example-tracing tutors, a novel type of ITS that are built "by demonstration," without programming, using the Cognitive Tutor Authoring Tools (CTATs). The project's main contribution will be that it represents a stringent test of large-scale tutor authoring through programming by demonstration. A secondary contribution will be that it tests whether an open-access site (i.e., a site that is widely and freely available) with software tutors for math learning can attract and sustain user interest and learning on a large scale.
