Educators in elementary and secondary schools across the nation are struggling to improve and redesign mathematics and science education so that all students are well-prepared for the beginning of a new millennium. Policymakers are confronted with growing determination that a solid foundation in mathematics, science, and technology is essential not only to the economic but also to the social well-being of the nation. Indeed, a task for today's policymakers, parents, and communities is to ensure that all students are graduated from high school with a quality education that will enable them to contribute productively to society. Toward this end, the United States has set, as a matter of national policy, the goal of its students being first in the world in mathematics and science achievement by 2000.
However, national and international indicators of educational progress suggest that the country is still far from its goal, despite a growing reform movement aimed at achieving excellence and equity in education. Unresolved issues concerning the performance of students and teachers, the quality of instructional materials and teaching, and access to quality education for all students are matters still very much at the center of local, state, and national education agendas. Nevertheless, indications of forward movement abound: students are taking more advanced courses in science and mathematics, teachers are more aware of the need to change their conceptions of teaching and learning, and student achievement in mathematics and science has largely returned to or exceeded the levels set in the 1970s.
The spark for much of the current reforms came from early work in setting standards performed by professional associations of mathematics and science educators. In mathematics, the National Academy of Sciences laid out the broad outlines of mathematics reform in Everybody Counts: A Report to the Nation on the Future of Mathematics Education (MSEB 1989). The National Council of Teachers of Mathematics (NCTM) followed with two reports that made more specific recommendations-Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) and Professional Standards for Teaching Mathematics (NCTM 1991).
During this same period, consensus on new directions for science education was beginning to develop, though actual national standards were some years away. By 1993, the American Association for the Advancement of Science had issued two publications, Science for All Americans (AAAS 1989) and Benchmarks for Science Literacy (AAAS 1993), and the National Science Teachers Association produced Scope, Sequence and Coordination of Secondary School Science (NSTA 1992). These reports, as well as others, led to a national dialog on science standards resulting in the National Academy of Sciences' National Science Education Standards (NRC 1996).
The standards for mathematics and science education share many core ideas: high expectations for all students; in-depth study and understanding of core concepts; emphasis on hands-on tasks that promote active engagement with the subject matter; and a strong focus on reasoning, problem solving, and the ability to apply learning within broader contexts.
The standards in both subjects view teachers as the critical agents that enable students to meet these more demanding levels of performance. However, a large proportion of current mathematics and science teachers were trained when conceptions of teaching and learning were very different from today. Consequently, both sets of standards emphasize the importance of professional development for teachers. Previously offered as a sporadic set of brief workshops to train teachers in specific skills, professional development is now portrayed as a career-long process of continuously updating teachers' mathematics and science knowledge and teaching skills (Darling-Hammond 1994a). And although some school systems, schools, and teachers have begun to adopt practices consistent with the standards, mathematics and science educators recognize that full implementation of standards-based reform will take much more time (Jones et al. 1992; Lindquist, Dossey, and Mullis 1995; and NSF 1996).
Like professional development, equity remains an important challenge for educational reformers in mathematics and science education. At its base, equity means that each and every student has access to quality education regardless of background, race, ethnicity, or location. Some of the building blocks for equity are:
One of the critical issues currently facing educators is how to achieve equity and excellence amid the complexities born of an increasingly diverse national makeup. Of the 45 million children enrolled in elementary and secondary schools in 1994, approximately 15 million are ethnic or racial minorities and 6 million come from homes where English is not the primary language spoken (NCES 1996b).
There are still more challenges: how to make effective use of the information technologies that are now commonplace in homes and workplaces as tools for reforming education and improving teaching and learning productivity; how to ensure consistency in approach and quality among instructional materials, teaching, assessment of student learning, and policies formed at district or state levels; and, finally, how to continue learning how to improve-and what works and doesn't work in improving-the quality of education.
Clearly, the role education plays in our personal lives and in the nation's well-being has grown over the years. And the challenges in mathematics and science education-and in all school subjects, for that matter-are before us as educators, students,
parents, and community members. And although these challenges may differ from those of years past, it is not clear that there are necessarily more of them, nor is it certain that they are any more daunting than they once were. It may be that we are
more concerned and know more about mathematics, science, and technology education in this nation than we did 20 or 30 years ago. As shown in this chapter, what is certain is that we have a stronger research base and a deeper, more far-reaching set of
national and international indicators of performance than ever before. (See "Measuring the Performance of the Education System.") [Skip Text Box]
Measuring the Performance of the Education System

This chapter is organized into three main parts: first, a detailed description of student achievement in mathematics and science is provided; second, curriculum and instruction are examined; and third, teachers and teaching are addressed. These latter two parts are presented because they are the components of the education process thought to have the greatest direct influence on student achievement. The chapter concludes with a summary of trends in these three areas and an interpretation of what this may mean for educational progress.
Under the student achievement section, the performance of U.S. students in both national and international contexts is examined in order to address the following questions:
The second major section of this chapter, on curriculum and instruction, focuses on the following questions:
The third major section of the chapter examines the background of U.S. mathematics and science teachers in national and international contexts. The discussion centers on these questions:
Many national and international data sources-all based on national probability samples-have been mined in writing this chapter. The first section of this chapter can be examined from a number of perspectives using a variety of data sources. The discussion here draws on three primary sources: the National Assessment of Educational Progress (NAEP), the Third International Mathematics and Science Study (TIMSS), and the High School Transcript Studies. NAEP is a reliable indicator of achievement for U.S. students. Since the early 1970s, NAEP has conducted trend assessments every two years covering mathematics, science, reading, and more recently, writing. These assessments draw on nationally representative samples of 9- 13-, and 17- year-olds. To date, eight trend assessments have been conducted in mathematics and nine in science.
NAEP also conducts subject matter assessments periodically on a wider range of subjects including history, geography, civics, computer competence, art, and music. Subjects are covered on a rotating basis so that in one assessment, the focus may be on mathematics and science, and in the next, on history and social studies. These assessments draw on nationally representative samples of students in grades 4, 8, and 12 rather than the age groups used in the trend studies. Items in the periodic subject matter assessments are revised from time to time to incorporate new assessment strategies and reflect prevailing professional judgments about what students in a particular grade should be learning. The items used in trend assessments are fixed, so that performance in basic areas of skill and knowledge can be traced over time, even as curriculum emphases change. Results of these two kinds of NAEP assessments are not directly comparable because of these sampling and content differences.
The second source of student performance data used in this chapter, TIMSS, compares the mathematics and science achievement of elementary and secondary students in the United States with the achievement of students in other countries. TIMSS was conducted in 1994-95 by members of the International Association for the Evaluation of Education. It is the largest and most ambitious undertaking of its kind. Forty-five nations took part in TIMSS at the middle school level (seventh and eighth grades), and 27 at the elementary school level (third and fourth grades).[1] Achievement data and background information were collected from students in each country. Teachers and principals supplied information about instructional resources, practices, staffing, course content, and views of mathematics and science teaching. Curriculum guides and textbooks from 46 nations were analyzed to provide information on the content and skills students in different countries are expected to learn in each grade. Mathematics lessons were videotaped in a sample of eighth grade classrooms in the United States, Japan, and Germany to document differences and similarities in the content presented and the instructional approaches used.
TIMSS results have been published in several reports. Results of curriculum studies are presented in three reports: A Splintered Vision: An Investigation of U.S. Science and Mathematics Education (Schmidt, McKnight, and Raizen 1997) and two volumes-one for mathematics and one for science-that present international comparisons, Many Visions, Many Aims (Schmidt, McKnight et al. 1997; and Schmidt, Raizen et al. 1997). International achievement and survey results are available in four volumes, one for each subject by grade (Beaton, Mullis et al. 1996; Beaton, Martin et al. 1996; Martin et al. 1997; and Mullis et al. 1997). Results from the survey of eighth grade U.S. teachers are presented in Mathematics and Science in the Eighth Grade (Williams et al. 1997). Syntheses of U.S. findings from component TIMSS studies are published in two volumes of Pursuing Excellence, one for fourth grade (NCES 1997c) and one for eighth grade (NCES 1996c).
A third major source of information about student performance is the 1994 High School Transcript Study, which is based on the records of over 25,000 seniors who graduated from high school that year. The transcript study reports information such as the mean number of credits earned in each subject field and the percentage of students earning a given number of credits in particular subjects (NCES 1997e).
The discussion of curriculum and instruction is based largely on data from the TIMSS curriculum analyses, video observational studies, and teacher questionnaires. The technology portion of this section is drawn from a recent survey on the status of advanced telecommunications in public elementary and secondary schools (NCES 1997a).
The third section of this chapter, on teachers and teaching, is based on comparisons of data from the TIMSS teacher questionnaires with results from the National Survey of Science and Mathematics Education (NSSME) conducted during the 1993/94 school
year (Weiss, Matti, and Smith 1994). NSSME, which was initiated in 1977 and updated in 1985, is one of the most comprehensive sources of detailed information on the preparation and classroom practices of mathematics and
science teachers. The discussion of teacher qualifications is supplemented by data from questionnaires administered as part of the 1993/94 Schools and Staffing Survey. (See NCES 1996a.) Information on teachers' efforts
to implement educational standards in their classrooms is drawn from a school reform survey conducted in spring 1996 (NCES 1997d).
