*THIS BOOK IS AVAILABLE AS OPEN ACCESS BOOK ON SPRINGERLINK* This open access book is the product of ICMI Study 22 Task Design in Mathematics Education. The study offers a state-of-the-art summary of relevant research and goes beyond that to develop new insights and new areas of knowledge and study about task design. The authors represent a wide range of countries and cultures and are leading researchers, teachers and designers. In particular, the authors develop explicit understandings of the opportunities and difficulties involved in designing and implementing tasks and of the interfaces between the teaching, researching and designing roles – recognising that these might be undertaken by the same person or by completely separate teams. Tasks generate the activity through which learners meet mathematical concepts, ideas, strategies and learn to use and develop mathematical thinking and modes of enquiry. Teaching includes the selection, modification, design, sequencing, installation, observation and evaluation of tasks. The book illustrates how task design is core to effective teaching, whether the task is a complex, extended, investigation or a small part of a lesson; whether it is part of a curriculum system, such as a textbook, or promotes free standing activity; whether the task comes from published source or is devised by the teacher or the student.

Admired by Marx and Engels, the Surrealists, the Situationists, Walter Benjamin and Roland Barthes, the great utopian socialist Charles Fourier (1772-1837) has been many things to many people: a proto-feminist, a Surrealist ancestor, a cantankerous cosmologist, a social critic and humorist and to this day one of France's truest visionary thinkers. He was also, as this volume demonstrates, a maniacal taxonomist. In this zoological guidebook to cuckoldry and commerce, Fourier offers a caustic critique of the bankruptcy of marriage and the prostitution of the economy, and the hypocrisies of a civilization that over-regulates sexual congress while allowing the financial sector to screw over the public. Gathered together here for the first time are Fourier's two "Hierarchies" --humorously regimented parades of civilization's cheaters and cheated-on in the domestic sphere of sex and the economic sphere of buying and selling commodities. "The Hierarchy of Cuckoldry" --translated into English for the first time--presents 72 species of the male cuckold, ranging from such "common class" cases as the Health-Conscious Cuckolds, to the short-horned Sympathetic, Optimist and Mystical Cuckolds, and the Long-horned varieties of the Irate, Disgraced and Posthumous Cuckolds. For Fourier, these amount to 72 manifestations of women's "secret insurrection" against the institution of marriage. "The Hierarchy of Bankruptcy" presents 36 species of the fraudulent bankrupt: a range of Light, Grandiose, and Contemptible shades of financial manipulators who force creditors, cities and even nations to bail them out of ultimately profitable bankruptcies. In these attacks on the morality of monogamy and the perils of laissez-faire capitalism, Fourier's "Hierarchies" resonate uncannily with our contemporary world.

Jean-Leon Gerome has become a popular artist. More and more young people are showing interest in his work and collectors worldwide are hunting down pieces of ever increasing value. This volume is a condensed presentation of his monographs together with a catalogue raisonne."
