This proposal changes the focus of Intelligent Tutoring Systems from the provider (courseware, software, hardware) to the student. This focus promotes the development of open, interoperable systems. In turn, these systems reduce the cost to the student; school system, military because the provider conforms to open specifications (in contrast to proprietary solutions). We propose the following for Phase I: a system architecture specification, a student motion language specification, student records specification. We include prototype tools and mockuup course to demonstrate the feasibility of this approach. We intend to participate in industry standards and other public forums to promote this approach, these concepts, and the specifications. A unique feature of our proposal is to make the tools publically available. Like the success of the World Wide Web (Mosaic was publically available, Netscape commenrcialized it), we believe this approach will (1) standardize the key interfaces and promote interoperability, (2) provide low-cost solutions (download tools from the Internet). Commercial and publically available Intelligent Tutoring Systems.
