Describes a one-week workshop for biology graduate students designed to persuade these future biology teachers of the importance of good teaching; inform them of the techniques, theories, and procedures that can improve instruction and learning; and train them in these techniques. Organization and preparation are emphasized as essential in any…

Describes relatively simple and inexpensive experiments for demonstrating the immune response to honeybee venom in the American cockroach, "Periplaneta americana." (PR)

Provides instructions for teachers and students to culture protozoans for use in science laboratories. Sections include setting up a culture area, basic culture media, amoeba culture technique, powdered milk-wheat-rice medium, alfalfa medium, and uses of the protozoa in the laboratory. (PR)

Describes a technique to isolate unsheared bacterial DNA and subject it to restriction endonuclease enzyme digestion. (MDH)

Describes making three-dimensional models of cells, creating a mitosis bulletin board, and creating flip books to help students understand mitosis. (PR)

Describes using tetrazolium chloride as a chemical test for seed germination. (PR)

Presents a series of activities and a discussion of William Harvey's research to help students understand blood circulation. (PR)

Describes an inquiry lab that helps students discover the chemical nature of enzymes. (PR)

Proposes the use of a series of 11 casts of fossil skulls as a method of teaching about the theory of human evolution. Students explore the questions of which skulls are "human" and which came first in Homo Sapien development, large brain or upright stance. (MDH)

Presents the four program goals for biology set forth in the National Science Teacher Association's "A Focus on Excellence: Biology Revisited" to (1) address biosphere, human society, and individual needs; (2) encourage students to experience, understand, and appreciate of natural systems; (3) apply the basic concept of the biosphere; and (4)…

Details a project in which students assess the health of two seemingly different streams by conducting chemical and biological tests. Focuses on student and teacher use of a watershed educational project in Tennessee. (DDR)

The assumption that students will acquire positive attitudes toward science as they learn more science is no longer valid. This study confirmed the reliability of the Biology Attitude Scale. Whether a student is a biology major or nonmajor is not a determining factor when measuring the effect an introductory course has in changing attitudes toward…

Outlines an in-depth case study of teachers' use of image processing in biology, earth science, and physics classes in one high school science department. Explores issues surrounding technology implementation. Contains 21 references. (DDR)

Outlines the experiences of a teacher in the National Oceanic and Atmospheric Administration's (NOAA) Teacher At Sea Program in which teachers are placed on NOAA vessels to work with professional scientists doing critical, real world research. (DDR)

Presents an account of one teacher's summer experiences on a vessel in the Bering Sea and the effects of those experiences on practice. Focuses on the teamwork among the science team, officers, and crew. (DDR)
