It begins with some comparisons with some commonly employed tools and suggests that how the tools are designed to be used poses limitations upon the learning tasks which are designed. The chapter concludes with some examples of how the tools have been used and the types of products that have resulted from its use. Development of educational software has had a long history of use of authoring environments that have enabled instructional designers, rather than programmers, to design and develop applications. The advantage of these tools has been that the designer did not need to be highly skilled in high level languages, but could use a simpler construction set of pre-programmed modules, often supported by a simple scripting language. The disadvantage was that the developer was limited to the pre-programmed modules available and to the underlying assumptions of the structured instructional design models adopted by the tool. The designer also had to work within the visual and procedural structures employed by the tool designers to represent the design process within which learning activities could be constructed....
