Describes a simple model to illustrate several aspects of the biochemical origin of life and the process of evolution through natural selection. The model has students predict the outcome of evolution in populations of beads. Instructional strategies using the model are also discussed. (Author/JN)

Application of a five-level developmental scheme to ascertain pupil attainment of four concepts considered to be prerequisite to an understanding of photosynthesis is described. Results indicate widespread deficiencies associated with these concepts. Implications for learning complex concepts in biology are considered. (Author/JN)

Discusses the role and use of microcomputers in scientific research, from monitoring instruments to controlling experimental processes. Included are descriptions of a computer-controlled protein sequencer and gene synthesizer, and microcomputer uses in medicine, physiology, biochemistry, and geology. (JN)

Describes an overnight camping experience in Gateway National Recreation Area, New York, with a class of physically handicapped elementary school children. Special problems exist, but virtually every activity could be adapted to the students' abilities. (WB)

Describes the Marine Education Leadership Training Program offered by East Carolina University. The program is intended to help teachers, marine education specialists and youth group leaders identify and define trends and issues in marine education. An internship and course work are among the program's components. (Author/WB)

Describes the semantic network technique of Rumelhart and Norman and by Lindsay and Normal for subject matter content analysis and explores its application to genetics. (CS)

The carabid beetle (Notiophilus) preys readily on an easily-cultured collembolan in simple experimental conditions. Some features of this predator-prey system are outlined to emphasize its use in biology instruction. Experiments with another potential collembolan are described in the context of developing the method for more advanced studies.…

Examines status of quantitative treatment verification, presents arguments for its use, and describes a study examining differences between two laboratory approaches in high school biology. Suggests the ability to demonstrate quantitatively that specific classroom events contribute to measured changes in students productivity will aid researchers…

Teachers can take advantage of students' interest in hair by using activities that focus on human hair in science or biology classes. Facts about the growth, purpose, and nutritional requirements for healthy hair are noted. Suggestions for measuring hair strength, and for making a hygrometer to measure general changes in humidity are included. (PP)

Suggests that biology teachers can serve an important role in turning humankind from nuclear warfare to peaceful cooperation. Argues that the school should lead the world in teaching about the universal will to live exhibited by all organisms and about the insanity of nuclear armament. (DC)

Fossil records are used to point out two major flaws in the scientific creationist theory: (1) factual evidence does not support the theory, and (2) the creationists' own characterization of the fossil record contradicts their theory. Claims that creationists avoid discussing specifics about their model because of weaknesses. (DC)

A story and questions are provided about a conflict between a science teacher and two students who do not want to dissect a frog. In the end, the teacher agrees with the students that alternative projects should be offered. (DC)

College students (N=46) enrolled in biology or physical science courses for nonscience majors were studied to determine the correlation of their test scores with test anxiety, sex, grade point average, and self-concept. (PB)

Reports on an island ecology course offered by Eastern Connecticut State College providing opportunities for students to study the ecology and natural history of organisms found in a variety of subtropical habitats in Bermuda. Explains student selection criteria, trip preparation, evaluation criteria, daily programs, and habitats studied on the…

Describes the modification of computer programs (BISON and POLLUT) to accommodate species and areas indigenous to the Pacific Coast area. Suggests that these programs, suitable for PET microcomputers, may foster a long-term, ongoing, inquiry-directed approach in biology. (DS)
