Amongst mathematicians and philosophers, Imre Lakatos is well known as a scientist who linked mathematics, philosophy and epistemology perhaps more closely than did any other mathematician during the second half of our century. But Lakatos also had a strong influence on mathematics education. This influence regards everyday mathematics education at school, as well as the scientific background theories. Particularly his well known book Proofs and Refutations (which has been published in German, as well), influenced the theory and practice of mathematics education (or "didactics' as German speakers prefer to say).
