A Microcomputer Approach to Exponential Functions and their Derivatives.
Peer reviewed Peer reviewed
Bloom, Lynette M.; And Others – Mathematics in School, 1986
An intuitive approach to exponential functions is described. Microcomputers are used to aid discovery of derivatives. (MNS)

Mathematics, Metaphors, and Human Factors: Mathematical, Technical, and Pedagogical Challenges in the Educational Use of Graphical Representation of Functions.
Peer reviewed Peer reviewed
Goldenberg, E. Paul – Journal of Mathematical Behavior, 1988
Computer software with graphic representations of functions can teach algebraic concepts, or can blur or obscure concepts of great importance. Making good use and bad use of visual imagery are each discussed. Then a general theory of interpretation of graphs is proposed, and a list of examples is presented. (MNS)
