Sound-slide programmed learning

Abstract

In an attempt to improve upon the traditional "lecture and textbook" mode of teaching, an Audio-Visual Response Teaching Machine was utilized for certain topics in gasdynamics. This teaching system was based on three elements: programmed instruction, a Question/Response/Answer technique, and continuous confirmation of answers. The teaching machine is a portable self contained unit consisting of a dual track cassette tape recorder, viewing screen, slide magazines, remote control, and a Respondex keyboard. Detailed scripts (including multiple-choice questions) were written, slides were prepared and synchronized audio-visual programmed lessons were assembled. The results are two individual packages on Reaction Propulsion Systems: The Brayton Cycle and Thrust: Power and Efficiency. Student reaction to these programs was favorable. It was concluded that this method should be used in a supplemental capacity to the course and recommended that work in this field continue.
