Because of the importance of the computer as an instructional aid, this book deals only with courseware for teaching machines that are in some way based upon the use of a computer. Consequently, much of the instructional strategy and domain-dependent subject matter will be embedded within some ·form of computer program. Most of the courseware that is of interest to us will therefore have characteristics similar to those of computer software. However, because some of the teaching material for a lesson may reside on other media (such as slides, fIlm, video tape or video disc) the direct analogy to software should not be over-emphasised.
In writing this book the rationale that has been adopted is as follows: chapter 2 gives a brief description of the authoring process and acts as a compendium of author languages and systems; chapter 3 discusses some examples of languages for use in simple CRTbased systems while chapter 4 enters into a description of multi-media languages; chapter 5 looks at some applications of CAL/CBT authoring tools; and finally, chapter 6 discusses potential future directions of development. 9 Conclusion Education is an interactive process that usually involves the transfer of knowledge from a teacher to a student.
In the remainder of this chapter our attention is turned to courseware development tools. Some indication is given of the wide variety of systems available for instructional software development and an outline evaluation methodology is presented. However, before surveying the range of software facilities for producing CAL/CBT materials, a simple taxonomy of authoring tools needs to be presented. This is the function of the following section. 2 The authoring process In the context of courseware authoring Pogue (1980) has suggested that: 'The broadest use of the phrase is to encompass the entire process of developing instructional materials for the computer, beginning with the educational process of identifying the learning needs of a target population and ending with the computer process of programming the lesson as the author intended.
