Using Hand-held Technology to Enhance Teaching and Learning in Mathematics

Abstract

Hand-Held Technology, such as Graphic Calculator(GC) TI83/TI83 plus, Computer Algebra System(CAS) TI92 plus/Voyage 200, Calculator-Based Laboratory 2(CBL2 ) and Calculator-Based Ranger (CBR ), has allowed for more innovative ways in teaching Mathematics. The introduction of Graphic Calculator TI83 / TI83 plus into A level Further Mathematics syllabus has certainly changed and opened up new avenues in the teaching of mathematics. By incorporating this technology into the mathematics classroom, students have a tool to facilitate their understanding of mathematics and allow them to explore mathematics concepts and theorems. The TI92 plus and Voyage 200(V200) incorporates graphical and numerical features with a powerful computer algebra system. This CAS has added a new dimension in the use of technology for teaching Mathematics. By using CAS, students are introduced to a new technology which will definitely enhance and enrich their learning experience in Maths. I will present some interesting questions which I encountered over the past few years when I used TI83 in teaching Mathematics. I also tried using V200, CBL2 and CBR as a teaching tool and will share some of my experiences in using them.
