## ICT IN MATHEMATICS

Spreadsheets (Unit A4 and Unit E1)

From doing repetitive calculations to showing patterns in certain number manipulations, spreadsheets can play an important role in mathematics at most levels. Spreadsheets can manipulate variables or parameters to see certain effects that can be more clearly and quickly demonstrated with the use of spreadsheets. Students can also request various types of charts to be plotted from values entered into a spreadsheet.

Teachers could prepare templates which have values already entered in order to illustrate effects from the manipulation of variables which is appropriate for work on simulation and modelling. At a more advanced level spreadsheets could be designed by the pupils themselves in order to help to solve a realistic and contextual problem (see Unit E1).

Information and Communication (Unit A7)

Students can use applets available on the Internet for performing mathematical games and solving mathematical problems.

Modelling and Simulation (Unit B3)

Students can use simple modelling packages, such as Mathematica, to gain insight into mathematical functions. Also the graphic calculator can be used for this purpose. We should be aware of the fact that this feature of ICT will change – some say completely – the curriculum of mathematics itself. It gives students access to easy to use tools for skills they themselves had to learn before these tools where available. This implies a shift from drawing graphs for functions to interpreting graphs drawn by ICT-tools.

Modelling and simulation can also be used in special software for geometry and stereometry; which will give the students a better understanding of figures in plane and space.

Statistics (Unit B4)

Using suitable software tools takes the pain of hours of calculation out of statistics and provides students with the means to analyse results.
