Food safety science is an important field due to its practical applications in maintaining public safety and confidence in consumer goods. A significant component of food safety science is the detection and regulation of heavy metals in food. Heavy metals such as mercury (Hg) are of particular concern because of their potential to damage the…

One of the guiding principles highlighted in "A Framework for K-12 Science Education" (NRC 2012) states that "children are born investigators," claiming that students construct their own understanding of the natural world even before they learn about it in formal learning settings. Even if students lack a thorough…

Pursuing both disciplinary authenticity and personal relevance in the teaching and learning of science in school generates tensions that should be acknowledged and resolved. This paper problematizes and explores the conceptualizations of these tensions by considering personal relevance, disciplinary authenticity, and common school science as three…

Due to the interdisciplinary nature of environmental education, addressing the range of socioscientific issues included under the umbrella of sustainability can be challenging for educators working within the context of mandated state subject area standards. Two states (Washington and Vermont) have been recognized as leaders in incorporating…

The purpose of this study was to evaluate a typical Chinese high school biology textbook using the textbook standards of the American Association for the Advancement of Science (AAAS). The data were composed of three chapters selected from the textbook. Each chapter was analyzed and rated using the AAAS textbook standards. Pearson correlations…

This critical analysis examined research on evolution in the United States between the years 2000-2014, spanning early classroom implementation of the National Science Education Standards to current research findings. First, we sought to understand how the research literature published between 2000 and 2014 contributed to knowledge of evolution…

Analyzes the science frameworks of 49 states and the District of Columbia to determine the emphasis given to evolution in these documents at the middle and secondary levels. Collectively, the 50 frameworks emphasized evolution in a manner that suggests that if the public's support for standards-based curricula is a reality, the study of evolution…

Discusses the standards regarding evolution in grades K-12. Lists standards created by some states in response to creationist pressures to obscure or eliminate evolution from their standards. Presents another list of criteria about teaching evolution. (ASK)

Describes strand maps in general and in relation to the Benchmarks for Science Literacy. Examines three draft maps entitled "Evidence and Reasoning", "Scientific Investigations", and "Scientific Theories" which together represent one section of Benchmarks Chapter 1 on scientific inquiry. (Author/MM)

Discusses science education in the United States, which is in the midst of an unprecedented reform movement driven by national standards developed with support from the federal government. These standards are redefining the character of science education from kindergarten to the post-graduate education of scientists and science teachers. The new…

Suggests specific ways in which laboratory activities might be slightly modified to increase students' understanding in science, based on recommendations from the National Science Education Standards and on constructivist understandings of the learning process. Contains 42 references. (WRM)

Describes common features in the radiation chemistry of food components, and illustrates how product yields are predicted. Presents data that pertain to the radiolysis of the nitrate ion, metmyoglobin, myosin, and tripalmitin. (CS)

Using literature in science instruction has the potential to increase student motivation and to improve student achievement in both literacy and science. The process of identifying high-quality picture books, however, can be challenging and time consuming for teachers. The authors identified 74 science-based picture books from the annual Teachers'…

Reports the results of a 1983 survey of state agencies involved in certification, with attention focused particularly on the requirement for teaching in the basic academic subject fields--English/language arts, social studies, science, and math. (HOD)

The Council of Chief State School Officers (CCSSO) partnered with Andrew Porter and John Smithson of Wisconsin Center for Education Research (WCER) to develop an advanced, in depth approach to collecting and reporting data on the "enacted curriculum" in K-12 math and science, i.e. the actual subject content and instructional practices experienced…
