Describes how the synthesis of urea, 150 years ago, was a major factor in breaking the artificial barrier that existed between organic and inorganic chemistry, and this contributed to the rapid growth of organic chemistry. (GA)

Discusses anthropomorphic explanations and the use of teleological formulations in biology teaching. Examines whether the teachers' use of "pictorial language" is taken at face value by students. (Author/GA)

Investigates the possible relationships between the ability of introductory college genetics students to perform Piagetian formal operational tasks and their ability to solve problems requiring genetic analysis. (Author/GA)

Advocates the use of nonparametric techniques, when teaching data analysis to undergraduate life-science students, to circumvent their poor mathematical training. (GA)

Presents a set of exercises designed to take the student past cultural barriers to environmental awareness. The purpose is to pose environmental problems through contrived, open-ended situations, permitting a wide variety of approaches, attitudes, and values to come into play. (Author/GA)

Outlines some specific approaches and ideas that will add a new dimension to an introductory college biology course rendering it more motivational, personalized, and meaningful to the students. (GA)

Describes some laboratory exercises using the mole crab, Emerita talpoida, as an experimental animal for the study of osmoregulation. (GA)

Investigates the reasons for students' failure in an introductory volumetric analysis course by analyzing test papers and judging them against a hypothetical ideal method of grading laboratory techniques. (GA)

Describes some of the advantages of having the science teacher develop, use, maintain, and troubleshoot the new instructional materials. (GA)

Describes a nonmathematical course in quantitative methods to train bioscience students to formulate problems directly in the programing language and to use the programs so developed to analyze the implication of the hypotheses. (GA)

Describes a minicourse on energy and the environment for nonscience majors. A simulator is used to provide the student with a background on energy and environmental problems. (GA)

Describes two tests, T-4 and T-3, for hypothyroid based on the binding of the hormones by proteins. The tests were performed in courses for physicians, clinical chemists, laboratory technicians, and undergraduate science students by the individuals involved and on their own sera. These tests are commercially available in kit form. (GA)

Gives summaries of conclusions for two studies: a literature search on "The Status of Pre-College Science, Mathematics, and Social Science Education 1955-1975," and the "Case Studies in Science Education (CSSE)," which attempt to describe the status of precollege science education in the 1976-77 school year. (GA)

Presents an analysis of the causes of earthquakes. Topics discussed include (1) geological and seismological factors that determine the effect of a particular earthquake on a given structure; (2) description of some large earthquakes such as the San Francisco quake; and (3) prediction of earthquakes. (HM)

Presents space perception as an important interdisciplinary topic. A unit on space perception in a senior-level animal behavior course is described. The unit is introduced with a survey of how the students describe areas around them. The survey is followed by a discussion on personal space. (HM)
