Editorial: The greatest calamity in the history of science The greatest calamity in the history of science was the failure of Archimedes to invent positional notation. - Carl Friedrich Gauss Although it has increased in the past 20 years, the number of mathematicians in the United States who devote large amounts of time to thinking about mathematics education below the college level is rather small. As a consequence, there is no standard set of activities that define the occupation. Teacher preparation and professional development are obvious areas for work, but at my university, we don't have an education school, and no courses specifically for training teachers. So, I have had to figure out for myself what I might do to improve mathematics education (besides serving on committees and attending workshops, of course!). What I have mainly done is, try to think about the mathematics of elementary school: what it involves, and what is needed to develop it robustly - the kinds of ideas that might go into writing a set of standards for mathematics education. I have found this to be a serious intellectual challenge. It is this challenge that has kept me thinking about mathematics education. After reading the book Knowing and Teaching Elementary Mathematics by Liping Ma, and serving on the committee that produced Adding It Up, I had the sense that place value was a topic that needed more attention in US math instruction. As part of a series of workshops at the Park City Mathematics Institute, whose goal was to have mathematicians attend to and discuss aspects of the elementary curriculum, I undertook to write an essay about place value. Accordingly, I sacrificed a substantial part of a visit to the wonderful Newton Institute in Cambridge, England, to produce Taking Place Value Seriously (joint with Susanna Epp; available online at http://www.maa.org/pmet/resources/PVHoweEpp-Nov2008.pdf). (Not to complain too much - I also wrote a research paper.) One of biggest surprises of that project was the realization that there was no standard short name for the basic building blocks of the decimal system, the numbers like 2 and 70 and 300 and 4,000, that have only one non-zero digit. Such a number can be described as a "digit times a power of 10", but this is rather cumbersome; also, it assumes the concept of "power of a number", while one would like to draw student attention to these numbers before that concept is available. So I gave them a name. In the first draft of the essay, I called them "very round number"s. However, some of my Park City colleagues found this insufficiently dignified, so the term that survived to the essay is "single place number". After writing the essay, I took every opportunity I had to advocate more attention to place value in US math education. (I found that Singapore does a much better job with place value, which reassured me that I was not crazy to emphasize it.) But I gradually realized that I was not communicating what I wanted to, and that the reason was connected to the lack of a name for a "digit times a power of 10". Place value in the US is treated as a vocabulary issue: ones place, tens place, hundreds place. It is described procedurally rather than conceptually. Place value is treated as the rule that tells you how to read a number, not as the idea of expressing any number as a sum numbers of a very special form:"digit times a power of 10". It is this idea that gives place value notation its amazing power. Not only can we write very large numbers efficiently, we can compute with them by simple algorithms, based on two fundamental principles: 1) know how compute the sum or product of two "digit times a power of 10"s (in addition, only worry about the case when the powers of ten are the same); and 2) combine the results of 1) using the Rules of Arithmetic. Because of the particular nature of the special numbers (they are "digit times a power of 10"s!), step 1) largely boils down to knowing how to compute with digits: the addition facts and the multiplication facts. This small amount of memorization gives one the potential to do an infinite number of computations. But talking about place value procedurally prevents us from saying this. It takes the focus away from the nature of the special numbers and what we are doing with them, and turns it to the question of how to read numbers. This is of course very important, but it is only the very beginning, the first step in understanding the marvelous conceptual leap that place value embodies. So my plea to the mathematics education community is: let's talk conceptually about place value, and help teachers think conceptually about place value. And as an enabling first step, let's find a short catchy standard name for "digit times a power of 10"!

ICMI elections: the Nominating Committee is working The International Commission on Mathematical Instruction (ICMI) Nominating Committee was formed, according to the present procedures for election, with the purpose of presenting the slate of nominations for the ICMI Executive Committee (EC) in preparation for the ICMI elections done at the ICMI General Assembly (GA). The Nominating Committee consists of seven people, each with full voting rights. None of its members shall be eligible for nomination for the ICMI EC. The present ICMI Nominating Committee is chaired by Bernard HODGSON (Canada) and includes the President of ICMI William (Bill) BARTON (New Zealand) and the President of IMU Ingrid DAUBECHIES (USA). Two other members were chosen at random from nominees of ICMI/IMU member countries, and they are Shobha MADAN (India) and Dirk SIERSMA (Netherlands). The other two persons were chosen by the IMU EC and by the core members of the ICMI Nominating Committee; they are Jill ADLER (South Africa) and NGUYEN Chi Thanh (Vietnam). This Nominating Committee shall analyze the proposals sent by the Adhering Organizations and will produce, by March 2012, a nomination slate, to be called the "ICMI Nominating Committee slate". This slate shall consist of a unique candidate for each of the four ICMI officers (President, Secretary-General, and two Vice-Presidents), plus at least seven nominees for the remaining five members ("Members-at-Large") of the ICMI EC to be elected. When forming this slate, the ICMI Nominating Committee is authorized to nominate any duly qualified person for each position. Two months prior to the ICMI GA, the Secretary-General of ICMI will send to the Adhering Organizations and member representatives to ICMI the ICMI Nominating Committee slate, accompanied by a CV for each of the candidates on the slate, plus a list of all nominations submitted to the ICMI Nominating Committee in due time. From the floor of the General Assembly, delegates may present additional nominations from the list of previously proposed candidates that satisfy some additional conditions that can be found in the procedures for election.

Publications of Interest to the ICMI Community: IACME 50 years The Editorial Board of the Journal of Research and Training in Mathematics Education and the board of the Interamerican Committee on Mathematics Education CIAEM decided to publish a special series of notebooks designed to commemorate 50 years of IACME. We have titled this special series as IACME 50. This includes 3 issues of the Journal: 7. 8 and 9. In them you will find articles and documents and central protagonists in the history of CIAEM at different times, as well as researchers from Latin America who are starting, more recently, in the tissues of this new scientific and professional discipline is built around Teaching and Learning of Mathematics. The number 7 in this series consists of two sections: the History of Early Writings of CIAEM and Ubiratan D'Ambrosio. The first section contains articles of intellectuals associated with the conference and especially people who devoted much of their effort to the growth of this discipline in the region: Stone, Fehr, Santal?, D'Ambrosio, Basque and others, some of them pleasant memory. The second section includes three articles written in the 50s of last century by Ubi D'Ambrosio, a leading figure in the American region of major influence in the international community of mathematics education. The number 8 includes articles on an essential theme: Media and Hypermedia in Mathematics Education. Invoked in a very general work on the participation of technologies, videos, history, art education in different contexts and different approaches. There are implicit assumptions in the selection of these works, as the appreciation of diversity and integration required of approaches or instruments involved in the mathematics classroom chores. The number 9 includes other relevant contributions on various aspects of mathematics education, but revolving around one central issue which is the training of educators, curriculum, competencies, evaluation, perception, initial training, training ... The focus is on a convergence imbricated about the Teaching of Mathematics. http://www.cimm.ucr.ac.cr/ojs/index.php/CIFEM No. 9 (2011) Curriculum, assessment, teacher training, skills No. 8 (2011) Media and Hypermedia No. 7 (2011) History and perspectives.
