The using calculator in mathematics learning is an ordinary
thing in this era for everyone in elementary school until university. So, many
research shown and explain about the calculator. There are two types of
calculator by its utility, common calculator and scientific calculator. The
common calculator usualy used in daily life.
The research was held in SMK Muhammadiyah IV Yogyakarta on
February 2003 to get the describtion about the using calculator in mathematics
teaching learning process. The reseacher gave the introduction about using
calculator before the research was held. The graphics calculator is used to
solve the linear equations and non-equations.
There are four steps to using graphics calculator in
mathematics teaching learning activity. First step is to understand the
importance of graphics calculator. Second step is to understand the theory and
how to use the calculator to solve the the questions about linear equations and
non-equations. Next step is to input data of the question in to the calculator.
It will be prosessed to change the mathematics language to become the language
of calculator. The last step is to construe the output that appeared in the
monitor and get the conclusion.
The obstacle of using grapics calculator is the students be
in trouble to translate the mathematical sentences in to the language of calculator.
Also on other way, the students hard to explain the output of calculator in to
the mathematical sentences.
By using the graphics calculator, mathematics teaching
learning process in linear equations and non-equations topic will be more
easier and fun than before. If the using of calculator is not balanced by
conseption the procedure of operation and mathematical thinking, so it will be
caused the dependence, lost of student’s confident and indolent to think
