The calculator is an alectronic device that can be
used to count and can be used as well in math-related learning such as math,
aconomics, and others. In developed countries, the use of calculators has been started
since education in primary schools through education with the highest level. The
use of calculators that can help students learn so much in use among students.
According Wasito, the calculator is a specialized tool
to perform arithmetic with the preparation of data and instructions are
included this. Benefits of the use of calculators, among others, helped to
understand mathematical concepts, help to strengthen computational skills,
develop high level thinking skills, improve problem-solving skills, and make
problem-solving more realistic.
Implementation of research objectives is to identify
the use of graphing calculators in mathematics learning and knowing how big the
response of the students to use graphing calculators in mathematics learning
process. Achieved the expected goals is to understand the learning activities
of teachers and students in learning mathematics.
The results include several things, among others,
important order from Texas Instruments calculator TI 89, the discussion of
systems of linear equations of two variables with the help of Texas Instruments
calculator TI 89, the response of the students to use calculators in
mathematics learning processes, and stages the use calculators as a tool aids. Several
important orders from the Texas Instruments calculator TI 89, among others,
solve command, simult command, and expand command.
Student responses to the use of calculators in
mathematics learning process, among others, the calculator allows students to
do the sum, the calculator makes the class more interesting, difficulty
understanding the questions that will be included into the calculator, the
difficulty to analyze and provide conclusions about the response of the
calculator, as well as cause lazy students to think and have a dependency on
calculators.
Stages of the use of calculators as a learning tool
in mathematics at SMK Muhammadiyah Yogyakarta IV, among others, the first step
to understand the importance of the graphing calculator, the second stage to
understand the theory and use of graphing calculators in problems solving, the
third stage of entering data into the graphing calculator problems, and the
fourth stage of interpret the appearance the graphing calculator screen and
draw conclusions.
