In response to Soviet advances in science and engineering education, the country's top scientists with the support of the federal government in 1956 launched an unprecedented program to reform pre-college science education in the United States. Drawing on a wide range of archival material, John Rudolph traces the origins of two of the leading projects in this movement in high school physics and biology. Rudolph describes how the scientists directing these projects drew on their wartime experiences in weapons development and defense consultation to guide their foray into the field of education and he reveals how the broader social and political conditions of the 1950s Cold War America fundamentally shaped the nature of the course materials they eventually produced.
