A third party evaluation was conducted of an experiment in service training program (Project Interact) in career education using duplex (two-way) television to reach several groups in different cities simultaneously. Two main aspects of the project were under study: the particular curriculum content on career education and the use of the Texas Telecomputer Grid. The Texas Telecomputer Grid, a telecommunication network, is operated by Central Texas College in Killeen, Texas. Satellite facilities are located in Dallas, Fort Worth, and San Antonio, Texas. The project evaluation relied on two main inputs: questionnaires completed periodically by the participating teachers and review of the programs by an advisory committee of media and career education experts. Results indicated that staff dedication was high, but that the program was impaired by mechanical failures of the Grid. It was concluded that the Grid is a useful teacher training device for certain purposes and under certain conditions. An appendix includes examples of all the instruments employed in the evaluation.
