9 – Modelling and Spreadsheet Calculation

On the basis of observations in the present German educational system and the requirement to include modelling activities as a part of the general aim in mathematical education the advantages of spreadsheets will be demonstrated with the help of three examples. To start with the assumption that, the earlier one begins with the concept of modelling the better one acquires these abilities in the course of the school time and the better one recognises mathematics as a part of our world, modelling activities in lower secondary schools will be shown. In the modelling process spreadsheets could be used with models which are based on systematic testing, iteration and recursion, simulation, parameter variation, visualisation and data-handling in an elementary fashion.
