New science standards and reform recommendations spanning grades K--16 focus on a limited set of key scientific concepts from each discipline that all students should know. They also emphasize the integration of these concepts with science practices so that students learn not only the "what" of science but also the "how" and…

Secondary school educators are told to teach more mathematics and science to their students to help them become more proficient in the two subjects. Coordination of mathematics and science teaching is recognized as another means of improving proficiency. The National Science Foundation has funded the "Mathematics, Science and Technology…

Presents an exercise that examines the lever systems that function in the chelae of the American lobster. Involves calculating the mechanical and distance advantages of the crusher and pincer chelae and estimating the actual forces generated by the contraction of the muscles and the magnitude of the forces transmitted around the fulcrum to the tip…

Discusses genetics and heredity and their relation to human behavior. (JRH)

Describes several teaching exercises combining art and ecology that have been used in advanced ecology courses and may be adaptable to art criticism. Considers the nature of art, the ecological content of art, and the artistic form of ecological models. Contains 40 references. (DDR)

Introduces the course "Infectious Diseases and History" which is designed for freshman and sophomore students. Aims to teach about infectious diseases, develop skills of using libraries and computer resources, and develop oral and written communication skills. Focuses on tuberculosis as an example of an instructional approach and…

Describes an assay to determine the rate of photoreduction of 2,6-dichlorophenolindophenol (DCPIP). Acquaints students with experimental design and teaches them how to evaluate and communicate their results with the goal of enhancing their scientific literacy by integrating basic chemistry and arithmetic into their practical experience. (JRH)

Describes a college utilizing interdisciplinary studies and off-campus learning experiences to unite the classroom and reality and thus acknowledge the social significance of science. (LS)

Points out the challenges of educating students about bioethics and the limited training of many biologists on ethics. Discusses the basic principles of ethics and ethical decision making as applied to biology. Explains the models of ethical decision making that are often difficult for students to determine where to begin analyzing. (Contains 28…

The Gaia Hypothesis emphasizes the interactions and feedback mechanisms between the living and nonliving process that take place on Earth. Employing this concept in instruction can emphasize the interdisciplinary nature of science and give a planetary perspective of biology. (PR)

Discusses the history of the use of pesticides and biological control. Introduces the concept of biological control as illustrated in the use of the entomopathogenic bacterium Bacillus thuringiensis and highlights laboratory demonstrations of Koch's postulates. Includes an exercise that offers the student and teacher several integrated learning…

Develops a simple tree-ring laboratory to demonstrate the basics of dendrochronology. Provides two upper-level laboratory exercises primarily intended to demonstrate the specific dendrochronology subdisciplines of dendroclimatology and dendroecology. Suggests using the exercises separately or in unison as part of a multidisciplinary capstone…

Argues that biology students learn how to write effectively from biologists who write well. Presents a picture of a writing curriculum interwoven with a biology curriculum. Includes course-specific writing tasks. (DDR)

Details the teaching of an undergraduate plant-cell biology class in the manner proposed by Jean Baptiste Carnoy when he established the first institute of cellular biology. Integrates mathematics, astronomy, physics, chemistry, anatomy, physiology, and ecology. Contains 226 references. (DDR)

Discusses how the use of organizing themes can help to convey to students a sense of internal continuity within the discipline of biology and at the same time emphasize to them that viewing the study of biology as merely applied chemistry and physics is inaccurate and overly simplistic. (ZWH)
