This website is the homepage for Science for All Americans, a publication that advocates science literacy by recommending essential knowledge and ways of thinking for all citizens in a world shaped by science and technology. The book briefly discusses the recommendations and takes up the question of why such recommendations are needed. It presents a vision that emphasizes meanings, connections, and contexts rather than bits and pieces of information and favors quality of understanding over quantity of coverage. This publication is available as a book or on-line in English and Spanish.
