A 5-year case study was implemented to evaluate the two-way Carroll Instructional Television Consortium, which utilizes a cable television network serving four school districts in Illinois. This network permits simultaneous video and audio interactive communication among four high schools. The naturalistic inquiry method employed included gathering data through student pre- and posttests, student/teacher surveys, observation, and interviews. Inquiry objectives were to determine system effectiveness, system effects on the teaching/learning process, the level of acceptance of interactive technology, and project success. Preliminary results in the first year indicate, according to student evaluations of technical considerations, that the system has improved; according to improved in both effectiveness and efficiency; administrators and other faculty perceptions show increased satisfaction with the system; and students in remote interactive television classes achieved as well on the posttest as students in live classrooms. Seven references and data collection instruments are included. (LMM)
