Modelling with a Graphics Calculator

The Texas Instruments Calculator Based Laboratory used with graphics calculators, enables students to undertake mathematical modelling through problem solving using classroom generated data. The easy transfer of data to each student's calculator allows self–paced, independent work either individually or in small groups. There are opportunities for discussion between students and teacher and between the students themselves. The activities can facilitate cross–curricular links between mathematics and the sciences. They provide a means for concept development in the students and they demonstrate practical applications of mathematics. This study has evaluated the use of the CBL in a number of Scottish schools. It has shown that the activities are rich in mathematical concepts, that they can be tailored to the mathematical maturity of the students and that they enhance the quality of learning.
