Vacuum technology video instruction

About 2000 persons per year participate in some form of vacuum technology instruction. Compared to an estimated 3000 to 6000 persons per year who need some form of instruction in vacuum technology, an obvious unmet need for additional instruction exists. Video instruction can help meet this need. Video technology as it relates to instructional uses is briefly reviewed. Broadcast TV, cable TV, satellite TV, video tape, and video disks are discussed. High quality instruction requires a complete answer to the question ’’Who needs to know what?’’ and a systematic approach to the instructional design. The advantages of video instruction are primarily cost effectiveness and scheduling flexibility. The cost elements in video instruction include needs analysis, instructional development, video production, duplication, sales, distribution, and operation. The future of video instruction coupled with computer‐aided instruction offers exciting possibilities. Specifically, the video instruction available on vacuum technology topics is infinitesimal compared to the current need. Fundamentals, leak detection, and vacuum coating are identified as high need topics. A great opportunity exists to make a significant contribution to the vacuum industry through the development of vacuum technology video instruction.
