本章介绍了智能辅导系统（ITS）中课程开发的创作模型和系统。我们首先提出了一种对大规模 ITS 教授的主题（课程）知识进行建模的方法，并展示了它如何作为创作过程的框架。这种方法称为 CREAM（课程呈现和习得模型），允许根据分别涉及领域、教学法和教学方面的三个模型来创建和组织课程。该领域由能力模型（CREAM-C）支持，该模型通过逻辑链接表示和组织领域知识。教学观点允许通过对实现目标所需的技能进行建模并评估该成就对领域知识（CREAM-O 和教学模型）的影响来定义和组织教学目标。教学部分基于资源模型，该模型定义并指定了支持教学所需的不同活动 (CREAM-R)。 CREAM各部分的构建都有特定的创作工具和方法支持。整个创作系统称为 CREAM-Tools，允许教学设计师 (ID) 基于 CREAM 方法制作完整的 ITS 课程。尽管本文仅限于课程开发，但我们就最终系统如何支持其他 ITS 组件（例如规划器和学生模型）的构建提供了一些指导。
This chapter presents an authoring model and a system for curriculum development in Intelligent Tutoring Systems (ITSs). We first present an approach for modeling knowledge of the subject matter (the curriculum) to be taught by a large-scale ITS, and we show how it serves as the framework of the authoring process. This approach, called CREAM (Curriculum REspresentation and Acquisition Model), allows creation and organization of the curriculum according to three models concerning respectively the domain, the pedagogy and the didactic aspects. The domain is supported by the capability model (CREAM-C) which represents and organizes domain knowledge through logical links. The pedagogical view allows the definition and organization of teaching objectives by modeling skills required to achieve them and evaluating the impact of this achievement on the domain knowledge (CREAM-O and pedagogical model). The didactic component is based on a model of resources which defines and specifies different activities that are necessary to support teaching (CREAM-R). The construction of each part of CREAM is supported by specific authoring tools and methods. The overall authoring system, called CREAM-Tools, allows Instructional Designers (IDs) to produce a complete ITS curriculum based on the CREAM approach. Although this article is limited to curriculum development, we give some guidelines on how the resulting system could support the construction of other ITS components such as the planner and the student model.
