A Two-Point Videoteletraining System: Design, Development, and Evaluation
Abstract
The objective of the work was to design, develop, and evaluate an experimental two-point videoteletraining (VTT) system consisting of two classrooms equipped with audio and video equipment and communication links to enable two-way communication between the classrooms. The approach involved a survey of VTT systems; development of system design guidelines; definition of personnel, training, and logistics requirements; system design and development; and system evaluation. Findings were that student attitudes and performance of examinations wre comparable in originating and receiving classrooms. Students at the remote site were more likely to comment on deficiencies of the VTT system and were particularly sensitive to audio problems. Instructor acceptance of the VTT system was high. Several types of technical difficulties occurred during the field test. Most of these problems were resolved, through audio quality was never fully satisfactory. A preliminary cost analysis indicated that conducting training with a T1-based, two-way VTT system is more costly than sending an instructor to a remote site but that VTT can be less costly than having students travel to the instructor.
