The impact of informatics on the teaching of mathematics

Informatics and informatics based technologies directly impact on mathematics and its teaching. But there is also an indirect impact through developments in society which are supported by informatics. In the last thirty years developments in informatics and associated technologies have been many and fast; this has forced the understanding of their impact to change over time. For a more fundamental understanding of these impacts the role of informatics must be clear, both in real-life and in education. But also the role of mathematics needs clarification before the informatics impacts can be understood.
