Abstract
How to ask about effective research and practices in mathematics education? How to ask about the effectiveness of mathematics education? Crossed by concerns that arise from the struggle with these issues, this article launches itself in defiance: to think of mathematics education as a double: area and movement. Mathematics Education behaving as an area of knowledge and mathematics education behaving as a launching movement. What happens in between this double? Controversy. An unusual and untimely war, a fight that sews area and movement on one side, inside out, front and back, and movement and area and area and movement… On one side and inside out. A double. A movement that becomes territory. An area that cries out for movement. A controversial sewing, weaving one side and its inside out in a single plot. A controversy with mathematics understood as area, but also with mathematics understood as movement. A dispute, more than that, a controversy in the Greek way: polemikós, the art of war. Multiplicity. How many adjectives does math bear? How much can math tolerate being an adjective and not a noun? This writing explores three scenarios: one operates with mathematics education as a field of knowledge, addressing the creation of this area and its institutionalization processes; the other thinks over the movement of mathematics education; a third sews the previous scenarios weaving them: area and movement and mathematics education and Mathematics Education and first name and common name, and so forth…
