Data modelling using interactive charts

Djordje M. Kadijevich

This paper examines data modelling with interactive charts in upper secondary education. After defining data modelling per se, and explaining its relationship to mathematical modelling, data modelling with interactive charts is examined in detail, focusing on the main challenges in using them in the context of key data modelling activities. This examination is followed by a report of an empirical pilot study on the difficulty of these activities and the importance of this kind of modelling for upper secondary education. Implications for practice and research are included.
