Abstract: The entertainment potential of the videodisc is by now obvious to those who have followed the technological developments. Videodisc systems, however, are not limited to the ordinary linear playback mode (start at the beginning, go through to the end of the program), and the possibility of using electronic addressing of program segments and the random access capability now has educators excited about the videodisc as an interactive instructional tool. With automatic switching of a 30-min program disc from motion to the freeze-frame mode, it will be possible to intersperse motion sequences with still frames and greatly extend instruction times. Concepts can be taught with motion sequences, comprehension can be tested with still-frame questions, and the program can be continued by branching according to whether correct or incorrect answers are inputted through a keyboard. Preliminary estimates indicate that the cost of instruction due to the hardware will be about 30 to 60 cents per hour. If more than 20% of the disc contains still frames and the market uses 10,000 discs (or 100 discs 100 times each), then the cost for an hour of interactive instruction would be about 75 cents. The full potential for individualized interactive instruction must await the development of single-frame editing and encoding systems and the interactive keyboards.
