Abstract
It is known that scientific calculator has a long history of
development since it was available in the market in 1972. The
scientific calculators have been developed with innovative new
functionalities over the years. The end users of calculators (both
scientific and graphics calculators) have been expanded from mainly
civil engineers to students in middle, high schools and in
universities. This implies that the focus and development of
scientific calculators have been modified over the years. It is now
necessary for a calculator company to seek teachers' opinions and
feedbacks on a calculator's functionality before it is being
launched. We can say nowadays, most calculators are "Inspired by
Teachers" In this talk, author will use the "Natural Textbook
Display" created by Casio as an example to demonstrate that this
functionality is natural a feedback from mathematics teachers. A
scientific calculator displays the formula and expression as seen on
textbooks. In the mean time, some educators argue that current
excessive functionality of a scientific calculator is not acceptable
for math educators (for example, the functionalities of CAS,
Geometry application and etc.) in some cases; especially for
examination purpose. We will discuss these controversial issues and
see how calculator company, like CASIO, handles these issues.
