Improvements in U.S. science education require a coordinated curriculum from kindergarten through grade eight (K-8), with standards focused on several core ideas, according to a 21 September report from the National Research Council of the U.S. National Academies. The committee that authored the report recommended that K-8 science education offer students the opportunity to become versed in knowing, using, and interpreting scientific explanations of the natural world, and in other 'strandsrsquo; that comprise proficiency in science. Students also should receive a variety of learning experiences, including conducting investigations, sharing ideas with their peers, and using models. The report urges policymakers,researchers, and leaders in education to tackle gaps in science achievement that persist between white students and non-Asian minority students, and between economically advantaged and disadvantaged children. In addition, the committee found that although studies show that children can think in sophisticated ways, science education usually assumes that children are simplistic thinkers.
