Technological delivery systems currently available or in use are examined for adaptability by rural schools, especially high schools faced with increasing demands to expand curriculum. This report focuses on the Mid-Continent Regional Educational Laboratory's (McREL's) service area of Colorado, Kansas, Missouri, Nebraska, North Dakota, South Dakota, and Wyoming, but the information would be useful to policymakers concerned with rural schools in other regions. Descriptions, expenses, and advantages are given for audio teleconferencing, videotape lessons, interactive television, interactive video, and computer networks. Profiles are provided for 20 projects employing modern informational or telecommunications technologies to expand instructional access or quality. Project description, implications for rural schools, costs, comments about enrollments, evaluations, alterations, and name/address of contact person are provided for each project. A chart lists information about technology-oriented delivery systems already available in McREL's seven-state area. The report emphasizes delivery systems which schools could employ immediately without tremendous expense and those which combine technologies with face-to-face supervision. Practical advice for choosing technologies emphasizes practicality, resource sharing, overcoming political barriers to change, and adapting principles of successful entrepreneurship when implementing new technologies.
