Pembelajaran Matematika Berbantuan Kalkulator: Studi Kasus Penggunaan Kalkulator Texas Instrument TI 89 pada PBM Matematika di SMK MUHAMMADIYAH IV YOGYAKARTA

In developed countries calculator to get an important role in the process of learning mathematics. This is indicated by the use of calculators in mathematics learning ranging from primary education to higher education. Not only limited to that, research on the graphing calculator is indicated by the number of journals, books, conference reports and dissertations that discuss the graphing calculator. The importance of a calculator is to bridge the arithmetic and algebra. In the process of learning mathematics teachers need the ability to have a learning scheme. With the scheme are expected to have a systematic teacher in the learning of mathematics. 

So that learning will be systematic and structured math. Types of calculators had great development. Judging from their use calculator consists of two types. This type consists of two kinds, namely ordinary calculators and scientific calculators (scientific calculator). One example of a scientific calculator is a graphing calculator. Graphing calculator has its own advantages than regular calculator. The advantage lies in the ability of the calculator to solve math problems quickly and display them in graphical form. Another advantage of the graphing calculator to create a program that can solve math problems. The purpose of case studies is to identify the use of graphing calculators in mathematics learning processes and study the response of students to use graphing calculators in mathematics learning process. Targets to be achieved is to understand the activities of teachers and pupils in learning mathematics. Place Research Guide On SMK Muhammadiyah Yogyakarta IV. While the research conducted from February to June of 2003. To get an in-depth overview on the use of calculators in mathematics learning process. Researchers first introduced to the student calculators.Because researchers are given the opportunity to teach Highlights Equations and Inequalities then the first stage is to try to understand the importance of calculators in mathematics learning process. Stages use calculators as a learning tool in mathematics at SMK Muhammadiyah Yogyakarta IV, can be carried out as follows:

1.      The first stage is the stage of understanding of the significance calculator graph. The essence   of the understanding process is explained in
basic and detail about the graphing calculator.

2.      The second stage is the stage of understanding the theory and use of calculators graphs in  equations and inequalities to solve problems. Process The second is focused on how students understand the command, symbolic manipulation, and graphs to solve problems and equations inequalities with graphing calculator.

3.      The third stage, namely stage of entering data about the kalkakulator graph. The process of entering data into the calculator about the process move the language into the language of mathematics in terms of graphing calculators.

4.      The fourth stage is the stage interpretation of the graphing calculator screen and draw   conclusions.
