A Graphing Calculator-Based Instruction and Its Impact on the Teaching and Learning of
Mathematics in Malaysia
Introduction
Latest innovations in this era directed educators to move forward without holding on the old ways forthe sake of the future of their students. Likewise in mathematics education, most content areas shouldbe associated with the new technologies. Routine questions becoming less important; taken place byproblem solving and modelling. Mathematics achievement in our country is seen as a key factor in
the success of students in the school system. Thus, to improve students performances in Mathematicsbecome more demanding. Teachers concern in many mathematics classes is the attitude of thestudents toward the subjects. Poor attitude shown by students in Straight Lines and CoordinateGeometry therefore effect in poor mathematics achievement. The National Philosophy of Educationaims to produce a new generation of Malaysians who are able to think critically and systematicallyand who are able to use their knowledge of mathematics to meet the new challenges in this fastchanging world. The use of graphing calculators will cause changes in the way teachers teach and inthe way students learn mathematics.
Statement of the Problem
The teaching and learning of mathematics in many Malaysian schools has been reported to be too
teacher centered and that students are not given enough opportunities to develop their own thinkingskills (Ministry of Education, 2001). Research has also shown that students in many of todaysmathematics classrooms have little opportunity to explore mathematical patterns and processes(Embose, 1992) which can help them understand mathematical concepts better. Thus, learning
mathematics for many weaker students becomes uninteresting and boring. This poor attitude towardslearning mathematics is not helpful for the students, as it will lead to poor mathematics performances
(Dunham & Dick, 1994). Mathematics is traditionally thought of as the memorization of formulae, thelong and monotonous computation and the manipulation of numbers. The use of graphing calculatorsis one of the avenues that can inject new excitement and enthusiasm into the mathematics teachingand leaming process.
MethodologyThe study was carried out among Form Four students from eleven schools throughout Malaysia. Sixinstruments were used in this study (Mathematics Attitude questionnaire, Test of Logical Thinking(TOLT), Group Embedded Figures Test (GEFT), mathematics achievement test, the students andteachers perception questionnaires). Four-day training on the use of TI-83 graphing calculator weregiven to teachers. Instructional materials developed during the training session were used by theexperimental groups for about 10 weeks. At the end of the study, post-test of the mathematicsachievement test, TOLT, GEFT and the attitudes inventory were administered to the students.Questionnaires on the students and teachers perception on the teaching and learning of mathematicsusing the graphing calculator were also given to the experimental groups and their teachers.

Conclusion and Discussion
The graphing calculator used in this study shows encouraging effects for the potential of graphing
calculator in teaching mathematics. The results of this study is consistent with the TIMSS findingsthat students with the highest scores used calculators more frequently in mathematics instruction than
students with the lowest scores (Mullis et al., 2000). These results imply that the graphing calculator
not only helps students to process data and perform calculations, it may also help them to develop and
cultivate better thinking skills. The Group Embedded Figures Test (GEFT) indicate that the usage of
the graphing calculator seemed to have helped the experimental group students to be better able to
extract information and patterns from given data or diagrams. Thus, this study suggests that the
graphing calculator play an important role in helping the students acquire the ability to look for
embedded figure from given diagrams. From the results of the Attitudes Inventory, many of the
students even claimed that they would like to learn mathematics using the graphing calculator. These
results support the findings of a calculator project to evaluate the impact of calculators in mathematics
instruction carried out in the US, which claims that calculators can motivate and support students whohave negative attitudes towards mathematics (Bitter and Hatfield, 1994).
In conclusion, this study suggests that the use of graphing calculators in the mathematics classroom is
especially effective in helping students to perform better in mathematics, think more logically and
critically.
