A Splintered Vision: An Investigation of U.S. Science and Mathematics Education is the US report on the curriculum analysis component of the Third International Mathematics and Science Study (TIMSS) which was sponsored by the International Association for the Evaluation of Educational Achievement (IEA). The report summarizes data from the TIMSS curriculum analysis and integrates it with teacher questionnaire data from the US, Japan, and Germany on science and mathematics topic coverage and instructional practices. The authors of A Splintered Vision discuss and provide evidence of the unfocused nature of US mathematics and science curricular intentions, textbooks, and teacher practices. They offer the premise that producers of US textbooks and curriculum guides have attempted to answer calls for curricular reform by adding new content to already existing materials instead of devoting time to restructuring the materials. The authors also suggest that US teachers, inundated with a myriad of competing visions, are attempting to cover all the topics they confront in their resource documents and to meet all the instructional demands placed on them by those with a stake in education. In keeping with the incremental assembly line' philosophy in American society, US teachers also tend to lean toward a piecemeal approach to education. The authors speculate on what such practices may mean for the mathematics and science achievement of US students. The work is sure to spur discussion among educational researchers, policy makers, and others concerned about the future of mathematics and science education in the US.

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).

This book, based on detailed studies of eight innovations in mathematics and science education, has many insights to offer on current school reform. Since each innovation studied has taken its own unique approach, the set as a whole spans the spectrum from curriculum development to systemic reform, from c- centrating on particular school populations to addressing all of K-12 education. Yet these reform projects share a common context, a world view on what m- ters in science and mathematics for students of the 1990s and beyond, conv- tions about what constitutes effective instruction, and some notions about how school change can be brought about. These commonalities are drawn out in the book and illustrated with examples from the individual case studies that are reportedin full in BoldVentures, Volumes 2 and 3. The eight innovations-all of them projects that are well-known, at least by name, to U. S. audiences-are briefly described in chapter 1. Each was the s- ject of an in-depth, three-year case study. The research teams analyzed many documents, attended numerous project meetings, visited multiple sites, condu- ed dozens of individual interviews. The team leaders, having spent much time with mathematics or science education over long careers, looked at these reform projects through several lenses; the teams sifted through the mountains of data they had collected in order to tell the story of each project in rich detail.

This book presents comprehensive results from case studies of five innovations in science education that have much to offer toward understanding current reforms in this field. Each chapter tells the story of a case in rich detail, with extensive documentation, and in the voices of many of the participants-the innovators, the teachers, the students. Similarly, Volume 3 of Bold Ventures pre sents the results from case studies of five innovations in mathematics education. Volume 1 provides a cross-case analysis of all eight innovations. Many U.S. readers certainly will be very familiar with the name of at least one if not all of the science innovations discussed in this volume-for example, Project 206l-and probably with their general substance. Much of the education community's familiarity with these arises from the projects' own dissemination efforts. The research reported in this volume, however, is one of the few detailed studies of these innovations undertaken by researchers outside the projects them selves. Each of the five studies was a large-scale effort involving teams of researchers over three years. These teams analyzed many documents, attended numerous critical project meetings, visited multiple sites, conducted dozens of individual interviews. The team leaders (Atkin, Huberman, Rowe), having spent much time with science education over long careers, looked at these innovations through many lenses. It was a daunting task for each team to sift through the mountains of detail in order to bring the most compelling themes to the surface."

Examining the Examinations looks at the required advanced science and mathematics examinations taken by university-bound students in seven countries. This research focuses on topics covered, types of questions used, and performance expected from students. The book concentrates on comparisons of the examinations, illustrating their similarities and differences with selected questions taken from the actual examinations. The international comparisons presented offer a window on educational laboratories' in seven countries.

Based on a three-year study, the authors describe how comprehensive teacher induction systems can both provide teacher support and promote learning more about how to teach. This book calls for re-thinking what teacher induction is about, whom it should serve, what the 'curriculum' of induction should be, and the policies, programs, and practices needed to deliver it.
