The Instructional Architect: A System for Discovering, Recommending, and Combining Learning Objects

该项目创建了一个系统，该系统由一组在线服务组成，统称为教学架构师。教学架构师是一套数字图书馆的服务，包括四个工具，提供发现，演示，检查和学习对象的建议。数字图书馆的主要目标是为包括教师和学生在内的用户提供一种搜索和显示数字学习资源或学习对象的方式。通常，数字图书馆不提供方法或支持，重新组合和嵌入新的教学和课程中发现的学习对象。该项目提供了这一功能，包括一个额外的服务层，将覆盖和兼容现有的数字图书馆服务。这些服务包括加强现有数字图书馆提供的搜索能力，根据用户社区成员的反馈自动推荐学习对象，为将学习对象组合成课程提供教学支持，建立一个综合的基于网络的开发环境，在该环境中，学习对象可以组合成教学，以及一种能够基于共同兴趣自发形成新的用户社区的方法。虽然在创建数字图书馆方面已经取得了许多进展，对于具有因特网接入但需要技术和教学支持的大量教师和学习者如何访问和重新使用学习对象，存在相当大的改进空间。这一项目将产生一个系统，使人们能够更有针对性和更有针对性地获取学习对象，以创建教学，从而加强数字图书馆在促进有效的中小型企业教育和培训方面的作用。

This project creates a system comprised of a set of online services collectively called the Instructional Architect. The Instructional Architect is a suite of services for digital libraries consisting of four tools that provide for discovery, presentation, inspection, and recommendation of learning objects. A primary goal of digital libraries is to provide users, including teachers and students, a way to search for and display digital learning resources or learning objects. Often, the digital libraries do not provide methods or support for recombining and embedding discovered learning objects within new instruction and curriculum. This project provides this functionality by including an additional tier of services that will overlay and be compatible with existing digital library services. These services include the enhancement of search capabilities provided by existing digital libraries, automated recommendation of learning objects based on feedback from members of communities of users, instructional support for the combination of learning objects into lessons, an integrated Web-based development environment in which learning objects can be assembled into instruction, and a method for enabling the spontaneous formation of new communities of users based on shared interests.While many advances have been made in the creation of digital libraries, there is considerable room for improving how learning objects are accessed and re-used by the large population of teachers and learners who have Internet access but need technological and instructional support. This project will result in a system that will enable more focused and relevant access to learning objects for the purpose of creating instruction and thus enhance the role of digital libraries in promoting effective SMET education.
