This Small Business Innovation Research (SBIR) Phase I project addresses the difficulties of authoring intelligent tutoring systems. Intelligent Tutoring Systems have proven to be highly effective in delivering computer-based instruction, but have historically been expensive and difficult to build, requiring specialized skill in Artificial Intelligence and production systems programming. This proposal describes a Software Development Kit (SDK) composed of four components: Cognitive Model Authoring, Problem Authoring, Tool Authoring, and Curriculum Authoring. The proposed research activity centers around the first of these components: Cognitive Model Authoring. Cognitive Model Authoring is comprised of three separate steps: defining an object hierarchy, defining the goal structure of the problem task, and representing the behavior of the instructional system. The proposal seeks to define an object-oriented visualization of these steps, so that non-cognitive scientists can create cognitive tutors. This tool will decrease the amount of time it an experienced cognitive modeler to author the cognitive model portion of a tutor, and it will also decrease the amount of time it takes to enable a person with no cognitive modeling experience to create cognitive models.The broader impact of the Cognitive Tutor SDK is two-fold: (1) the easier production of new Cognitive Tutors, and hence the ability to bring them to market more quickly; and (2) the development of a Software Development Kit that could be independently marketed, so that other companies can produce intelligent tutors in other domains, languages, countries and markets.

这个小企业创新研究（SBIR）第一阶段项目解决了创作智能辅导系统的困难。 智能辅导系统已被证明在提供基于计算机的教学方面非常有效，但历史上一直昂贵且难以构建，需要人工智能和生产系统编程的专业技能。 该提案描述了一个软件开发工具包（SDK），由四个组件组成：认知模型创作，问题创作，工具创作和课程创作。 拟议的研究活动围绕这些组件中的第一个：认知模型创作。 认知模型创作由三个独立的步骤组成：定义对象层次结构，定义问题任务的目标结构，以及表示教学系统的行为。 该提案旨在定义这些步骤的面向对象的可视化，以便非认知科学家可以创建认知导师。 该工具将减少经验丰富的认知建模者编写导师的认知模型部分所需的时间，也将减少没有认知建模经验的人创建认知模型所需的时间。Cognitive Tutor SDK的更广泛影响是双重的：（1）更容易生产新的认知导师，因此能够更快地将其推向市场;以及（2）开发可以独立销售的软件开发工具包，以便其他公司可以在其他领域、语言、国家和市场生产智能导师。
