The Klein Project is an IMU-ICMI project that began in 2008 that aims to present contemporary mathematics for secondary school teachers. Klein Project materials are intended to inform, entertain and feed the enthusiasm of secondary teachers for their subject.
The project was inspired by Felix Klein’s book Elementary Mathematics from a Higher Standpoint, first published 100 years ago. It is intended as a stimulus for mathematics teachers, so to help them to make connections between the mathematics they teach, or can be asked to teach, and the field of mathematics, while taking into account the evolution of this field over the last century.
A Design Group was established, and plans formed to produce “vignettes”. A vignette is a short, readable piece on a topic of contemporary mathematics. A “Klein Vignette” is a short piece of writing about a single mathematical topic. It assumes the reader has some undergraduate mathematical knowledge, and at least a willingness to engage with mathematical writing. Klein Vignettes are not just “about” mathematics, they contain significant mathematics which is likely to be new to most secondary teachers.
