Three chemistry demonstrations are described: (1) modification of copper catalysis demonstration apparatus; (2) experiments in gas-liquid chromatography with simple gas chromatography at room temperature; and (3) equilibria in silver arsenate-arsenic acid and silver phosphate-phosphoric acid systems. Procedures and materials needed are provided.…

Reviews various provisions of a five-year, $23.5-million research agreement between Washington University and the Monsanto Company. The scientific focus of this venture will be on proteins and peptides which modify cellular behavior. (SK)

In wake of a number of highly publicized incidents of research fraud at some of the nation's most prestigious medical schools, the Association of American Medical Colleges (AAMC) has developed guidelines for coping with dishonesty in science. Highlights of these guidelines are reviewed. (Author/JN)

Describes an experiment to examine the kinetics of carbamate decomposition and the effect of buffer catalysis on the reaction. Includes background information, laboratory procedures, evaluation of data, and teaching suggestions. (Author/JN)

In arguing that the earth circles the sun, Galileo adopted a mode of reasoning that led not only to his prosecution by the church but also to the scientific methodology of hypothesis testing. (Author/JN)

Described is a method of simulating the formation of a DNA distribution, on which statistical results and experimentally measured parameters from DNA distribution and percent-labeled mitosis studies are combined. An EAI-680 and DECSystem-10 Hybrid Computer configuration are used. (Author/CS)

Presents arguments why science and engineering majors need to take courses in the humanities and why humanities majors need science courses. Suggests that aerospace education serves as an excellent and dramatic example of the correct approach to technological development and cites a sample course. (DC)

Raises questions and presents different views on the potential ethical dilemmas and legal issues resulting from the increasing amount of industrial investment in academic science. Gives examples of how different industries and universities have formed their relationships. (DC)

Describes an introductory physical geology laboratory which uses a semiself-paced, semiprogramed format involving weekly units, a weekly quiz, learning booklets, and undergraduate teaching assistants. Includes outline of weekly topics and a sample excerpt from the learning booklet. (DC)

Describes sensory assessment techniques and conditions for their satisfactory performance, including how they can provide open-ended exercises and advantages as relatively inexpensive and simple methods of teaching experimentation. Experiments described focus on diffusion of salt into potatoes after being cooked in boiled salted water. (Author/JN)

Briefly describes three science experiments: (1) universal curve for tape times; (2) depiction of magnetic fields; and (3) alpha particle detection by a Kodak LR 115:II plastic film. (SK)

Summarizes problems associated with teaching physically handicapped students in Wright State University biology classes. Presents techniques to modify lectures and laboratories, without changing course content, to accommodate these students. (SK)

Describes a variable-height wheelchair which can be raised 18 inches above normal chair height by means of an electrically operated screw jack. Photoqraphs illustrate the chair to be convenient and helpful for a handicapped chemistry student. (Author/SK)

Suggests a scientific approach for teaching problem solving that would aim at understanding the underlying cognitive mechanisms responsible for good problem solving and would then use the resulting insights to design explicit instructions for enhancing student's problem solving skills. (Author/SK)

Describes a single-concept program on alternating current series circuits that does not use the question and answer format usually associated with computer assisted instruction. The method serves a dual purpose, when used by the student as a final self-check of his/her understanding and by the teacher as a classroom demonstration. (Author/SK)
