Teachers often ask: How can I engage my students in the study of "real" science? The answer can be found in the National Research Council's "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" (NRC 2012). This framework calls for a new approach to science education and is the basis for…

Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

Chromosomes, alleles, chromatids, genotype, phenotype, mitosis, meiosis, fertilization--this vocabulary can be overwhelming, confusing, and difficult for students to tie together. However, since these terms are commonplace in the high school biology classroom, and are the basis for understanding both DNA and heredity, students must understand…

Students may wonder why they look the way they do. The answer lies in genetics, the branch of biology that deals with heredity and the variation of inherited traits. However, understanding how an organism's genetic code (i.e., genotype) affects its characteristics (i.e., phenotype) is more than a matter of idle curiosity: It's essential for…

Urges that biology teachers include the study of genetic anomolies, some very simple aspects of pedigree analysis, and related problems in order to produce citizens who are aware of the impact of science on their lives. (PEB)

This article presents a debate by two evolutionists, Ronald D. Simpson and Wyatt W. Anderson, and two creationists, Lane P. Lester and John N. Moore, over whether or not special creation should be taught in biology courses alongside the biological theory of evolution. (SL)

Describes the initially ignored research performed in 1900 by Archibald Garrod concerning the link between heredity and biochemical reactions. (MLH)

The physical and moral aspects of genetic counselling are discussed. Four case studies are presented. (CP)

Describes the use of a Pac-Man model (called a Pactype) in teaching various genetics concepts. Indicates that students can learn to make predictions, analyze patterns of inheritance, and evaluate hypotheses before being introduced to the genetics vocabulary. (JN)

Suggests that teachers use assessment in two equally important ways: (1) to periodically evaluate students' cumulative knowledge and understanding, a process known as summative assessment; and (2) to continually evaluate students' progress in learning, known as formative assessment. (DDR)

Since the discovery of the DNA double helix (in 1953 by Watson and Crick), technologies have been developed that allow scientists to manipulate the genome of bacteria to produce human hormones, as well as the genome of crop plants to achieve high yield and enhanced flavor. The universality of the genetic code has allowed DNA isolated from a…

Discusses the issue of mandatory genetic screening. Poses the question of the benefits, drawbacks, and motives involved. Provides a discussion activity to be used in high school biology classes consisting of a hypothetical situation and several questions. (CW)
