Abstract
Despite the appearance of more and more software packages for micro-computers designed to be used to improve the teaching/learning of introductory college mathematics courses including calculus, the acceptance and use of these packages as a regular part of the instructional paradigm is limited. The fact appears to be that we as yet do not know how to use them in mathematics education except as ad hoc add-ons to the course, simply because the relation between the subject matter and the software is unclear. The present paper is an attempt to provide the missing conceptual links between the topics, entities, operations, and problems treated in the texts, and the syntax and semantics of the software, to make the latter immediately understandable and therefore useable by student and teacher alike. In our view, there should be nothing extraneous to learn. To this end we adopt an object-oriented approach, the object-types being the mathematical objects themselves, and the actions being familiar mathematical operations on these objects. Next, we provide a modifiable tree-structure of menus of objects and actions as interface to the user to give flexibility. Lastly, we introduce "task descriptions" to guide, direct, record and communicate mathematical activities carried out by the student at the computer. We restrict ourselves here primarily to a discussion of object-types and actions, and the interface used, and illustrate with a prototype package for much of introductory calculus.
