PREFACE The Third International Mathematics and Science Study (TIMSS), sponsored by the International Association for the Evaluation of Educational Achievement (IEA) and the g- ernments of the participating countries, is acomparative study of education in mathematics and the sciences conducted in approximately 50 educational systems on six continents. The goal of TIMSS is to measure student achievement in mathematics and science in participating countries and to assess some of the curricular and classroom factors that are related to student learning in these subjects. The study is intended to provide educators and policy makers with an unpar- leled and multidimensional perspective on mathematics and science curricula; their implem- tation; the nature of student performance in mathematics and science; and the social, econ- ic, and educational context in which these occur. TIMSS focuses on student learning and achievement in mathematics and science at three different age levels, or populations. • Population 1 is defined as all students enrolled in the two adjacent grades that contain the largest proportion of 9-year-old students; • Population 2 is defined as all students enrolled in the two adjacent grades that contain the largest proportion of 13-year-old students; and • Population 3 is defined as all students in their final year of secondary education, incl- ing students in vocational education programs. In addition, Population 3 has two “specialist” subpopulations: students taking advanced courses in mathematics (mathematics specialists), and students taking advanced courses in physics (physics specialists).

PREFACE The Third International Mathematics and Science Study (TIMSS), sponsored by the International Association for the Evaluation of Educational Achievement (lEA) and the gov ernments of the participating countries, is a comparative study of education in mathematics and the sciences conducted in approximately 50 educational systems on five continents. The goal of TIMSS is to measure student achievement in mathematics and science in participating coun tries and to assess some of the curricular and classroom factors that influence student learning in these subjects. The study will provide educators and policy makers with an unparalleled and multidimensional perspective on mathematics and science curricula; their implementation; the nature of student performance in mathematics and science; and the social, economic, and edu cational context in which these occur.

In 1972, UNESCO put in place the World Heritage Convention, a highly successful international treaty that influences heritage activity in virtually every country in the world. Focusing on the Convention's creation and early implementation, this book examines the World Heritage system and its global impact through diverse prisms, including its normative frameworks, constituent bodies, programme activities, personalities and key issues. The authors concentrate on the period between 1972 and 2000 because implementation of the World Heritage Convention during these years sets the stage for future activity and provides a foil for understanding the subsequent evolution in the decade that follows. This innovative book project seeks out the voices of the pioneers - some 40 key players who participated in the creation and early implementation of the Convention - and combines these insightful interviews with original research drawn from a broad range of both published and archival sources. The World Heritage Convention has been significantly influenced by 40 years of history. Although the text of the Convention remains unchanged, the way it has been implemented reflects global trends as well as evolving perceptions of the nature of heritage itself and approaches to conservation. Some are sounding the alarm, claiming that the system is imploding under its own weight. Others believe that the Convention is being compromised by geopolitical considerations and rivalries. This book stimulates reflection on the meaning of the Convention in the twenty-first century.

John Golding brings to his writing the sure eye and profound sensitivity of a practicing artist. Perhaps best known for his seminal history of Cubism, Golding has long been regarded as one of the most outstanding art historians and critics of our time. This volume brings together many of his most important essays, and its publication will be celebrated not only by his admirers, but by lovers of art and language everywhere. Visions of The Modern covers a vast range of twentieth-century art, from Matisse and Cubism, Dada and Surrealism, to aspects of postwar American art. Some essays have been out of print, while others have appeared in periodicals not easily accessible to the average reader. Taken together, they establish a sustained, deeply informed account of many of the grandest moments in the art of this century. A much admired painter, Golding's unique balance of eye and mind infuses his exceedingly literate criticism. Combining a meticulousness in matters of fact with a capacity to write in a lucid, jargon-free manner, he addresses equally the sophisticated art historian, the cultural historian, and the general reader. An appendix to the volume is in the form of a dialogue between Golding and the philosopher Richard Wollheim. It provides additional insights into the origins and aims of abstract art, as well as revealing the mind of an invigorating artist at work.
