2 Science and Science Education in the United States Major Points in Chapter 2 Research and development (R&D) have become more internationally distributed even as R&D in the United States has grown substantially in scale and scope. Despite recent increases in some measures of scientific and mathematical proficiency, U.S. students on average still lag behind their international counterparts in some areas, and major gaps persist between groups in the U.S. population. Opportunities to participate in practice teaching and professional development are unevenly distributed and insufficient to transform the knowledge and skills of teachers as a whole. Parents recognize the need for improved science and mathematics education but tend to be satisfied with the amount of science and mathematics their own children study in school. Students and parents in other countries tend to associate success in science and mathematics not with innate talent but with the effort invested in those subjects. The National Science Board has identified better coordination and more effective teaching as the greatest needs of the U.S. educational system.

Even though most parents know that more mathematics and science are needed for students, they tend not to extend that reasoning to their own children. The National Science Board (NSB), which Sullivan vice chairs, recently reviewed the past three decades of reports on education in science, technology, engineering, and math- ematics (STEM) and, responding to a congressional request, developed a plan to “convert all those grand words into some forward action.” The board’s report, National Action Plan for Addressing the Critical Needs of the U.S. Science, Technol- National Research Council. 2007.
