Discusses the value of measuring noncognitive achievement of high school students and provides examples of basic evaluation techniques that can prove useful in measuring the overt behavior of students in the affective domain. (JR)

Describes a cooperative science program between an elementary and a secondary school in which high school students introduce topics and present demonstrations in biology to students in the elementary school. (JR)

Discusses the use of self-instruction in conducting a college laboratory program in biology. Six different laboratory exercises are set up in carrels, and students rotate around the carrels as they individually complete each exercise. (JR)

Discusses the nature of environmental education and identifies five major themes common to most environmental teaching materials. Advocates the need for a unifying theme in environmental education, and suggests that the discipline should be conceptualized around a model of decision-making.'' (JR)

Describes the natural habitat, life-history, and behavior of gerbils. These animals do not drink water, are virtually odorless, can withstand wide temperature ranges, and require minimal attention. As a result they have become popular in research and science classrooms in recent years. (JR)

Describes a microbiological experiment designed to study the competition between two species of bacteria. Experimental procedures and data obtained in conducting this experiment are provided, together with a discussion of the results. (JR)

Describes a high school summer program in field ecology designed to give students a first-hand understanding of their own biotic environment, to acquaint them with the organisms, relationships, and complexities of local habitats, and to introduce them to the methods and techniques of discovering and gathering information about nature. (JR)

Describes a method for measuring osmotic potential which is suitable for high school and college biology classes. This method introduces students to the hard-to-visualize technique of using density gradients to separate cells or cell constituents of differing densities. (JR)

Describes two experiments in physiology using a readily available marine vertebrate, the flounder. Representative results are presented from experiments which measure the effect of excess potassium on the flounder EKG, and the effect of temperature on heart rate of the starry flounder. (JR)

Reports the results of a study designed to identify the particular laboratory skills and techniques that should be incorporated into college courses in techniques for pre-service and in-service high school biology teachers. (JR)

Described is a science education program at Loyola University, Chicago designed for nonscience majors. Discussed are rationale for course offerings and course content. Emphasized is the need to reveal the nature of science and methods by which information is gained and theories formulated, rather than science content alone. (CS)

Described is a student exercise demonstrating plant biorhythms in Albizzia julibrissin. Initial preparation and methods for conducting the exercise are explained, and sample data graphs are included. (CS)

Described is an experiment that explores the relationships between conscious motor activity and autonomic processes such as breathing, blood pressure, and heart rate. Procedures for the construction and calibration of ball ergographs are outlined. (CS)

Described is a study which (1) examines opinions and attitudes of students towards various aspects of using living animals in studying biology and (2) identifies variables that affect student attitudes and opinions. Results include the finding that most students clearly favor live animal studies. (CS)
