The editors would like to thank especially Christel Biere and Herta Ritsche for their work on various versions of the chapters, Jonathan Harrow and GUnther Seib for their efforts to make translations from non-English speaking authors into sounding like they were from native speakers, and Roland Fischer for his brilliant idea to do an interview with Michael Otte. MICHAEL H. G. HOFFMANN JOHANNES LENHARD FALK SEEGER GROUNDING MATHEMATICS EDUCATION Michael Otte 's contribution Mathematics education has a long past, but only a relatively short history as an insti tutional effort. Even though already Plato's "geometry" or medieval arithmetic books have been exceptionally "didactical" in their approach to present themselves to the reader, it was only in the 1960s that the institutionalization of mathematics education as a scientific discipline started on a larger scale. Following major changes of the role and place of science in society, the universities began at that time to change their organizational structures or added new, often interdisciplinary, or ganizational units focusing on applied or basic problems of research. In a surprisingly consonant manner, this development in mathematics education was from the beginning an international one, crossing the then still existing bounda ries between East and West. Without disregarding previous work of didacticians of mathematics in the 19^ and early 20^ century and their influence, this can certainly be viewed to a larger degree as the result of the work of the International Commis sions on Mathematical Instruction (ICMI) inspired and chaired by Felix Klein work ing from 1908 to the twenties on a survey comparing mathematics education in many countries of the world. The International Commissions prepared the ground for a worldwide attempt to reform and revolutionize mathematics education. The reform movement of the early seventies in a way took up the international spirit of the International Commissions - particularly in the form of the ICME-conferences taking place every four years with the 1972 Exeter conference being a signal for a new beginning. Most of the contributors to this volume have played a role in this historical period - some more central, some more peripheral. Michael Otte's scientific life and career is situated in this field of historical forces and developments. It was a founding period for systematic research and a new disciplinary self-image of mathematics education. Also in Germany, the institution alization of basic research in mathematics education within university departments and faculties began. At that time the "new math" movement which also had been a truly international affaire just had run aground, and the Volkswagen foundation had called for a proposal to establish a central research institute in Germany to reach a deeper scientific understanding of the disastrous failure of the new math approach in German primary schools. The underlying idea was as deceptively simple as attrac tive: finding out the reasons and reconstruct them theoretically would also provide a 1 M. H. G. Hoffmann, J. Lenhard, F. Seeger (Eds.), Activity and Sign - Grounding Mathematics Education, 1-7. 2 M. HOFFMANN, J. LENHARD, F. SEEGER platform or a ground to anchor a new idea of how mathematics teaching and learn ing should look like in the future. The original design for the Institute included five chairs furnished with opulent financial means, in terms of manpower as well as other facilities. Michael Otte was to become appointed as one of the three chairs directing the InstitutfUr Didaktik der Mathematik of Bielefeld University in the next 25 or so years. ^ Very soon after the Institute began its work, two of his important books ap peared. The first one was Mathematiker Uber die Mathematik [Mathematicians on Mathematics] in 1974, and Mathematik, die uns angeht [Mathematics Concerning Us] in 1977. Two ensuing volumes were on mathematics and learning from text (see Keitel, Otte and Seeger 1980), and on epistemology, history and science (see Jahnke and Otte 1981). These four volumes like landmarks claim the big territory Michael Otte is covering in his scientific efforts, while the programmatic volume on Das Formale, das Soziale und das Subjektive. Eine EinfUhrung in die Philosophie und Didaktik der Mathematik [The formal, the social and the subjective: An introduction into the philosophy and pedagogy of mathematics, see Otte 1994], in a sense, is try ing to sum up what had been important
