The concept of packaged training is quite new. A typical training package consists of films, transparencies, slides, tapes and so on, supported by printed materials. Not all these different media of presentation are to be found in any one package; just that selection which will present the material in its optimal form. Sound films are usually a must, the printed matter invariably so; the element of choice normally centres round the method of projecting the still pictures, charts and tabulated matter.
