For example, it is possible to use interactive controls to vary Class B output stage bias and observe its effect on crossover distortion. Student reaction to the computer-based tutorials has been polled by questionnaires. Authorware tutorial on FET circuits Many students have asked for hard-copy of the tutorial material to be provided. During 1994 sabbatical leave allowed collaboration between the University of Essex and The University of Western Australia to further develop the Authorware tutorials to include the use of animation. The main advantage of Authorware is its high-level graphical method of creating interactive structures.
Animation is available, but often difficult to represent complex behaviour.
Its ability to work on two different platforms is better than HyperCard's restriction to one. However, there is the relatively high investment cost in the authoring tool itself to consider compared to other approaches. This was used to develop an introductory self-paced learning package augmenting material in the lectures on first year programming. Using a programming language that allowed rapid development of visual interfaces provided new opportunities beyond those available in HyperCard. However, it required programming experience.
