Summarizes several articles on safety in the science laboratory, an article on the science and history of chocolate, and an article on teaching nuclear physics from an historical perspective. (WRM)

Current reform documents place a strong emphasis on students' understandings of the nature of science (NOS). Interestingly, the importance of this educational outcome is not new and has been agreed upon as important by most scientists and science educators for the past 100 years. Despite numerous attempts, including the major curricular reform…

This contribution describes a new laboratory experience that improves medical students' learning of chronobiology by introducing them to basic chronobiology concepts as well as to methods and statistical analysis tools specific for circadian rhythms. We designed an autorhythmometry laboratory session where students simultaneously played the role…

The Project-Based Learning (PBL) approach enables the student to construct knowledge in his/her own way. Piaget, the founder of constructivism, saw the development of intelligence as a process involving the relationship between brain maturity and individual experience. The technology PBL (TPBL) approach confronts the student with a personal…

The food science course developed in Missouri combines basic scientific and mathematics principles in a hands-on instructional format as a part of the family and consumer sciences education curriculum. Throughout the course, students conduct controlled experiments and use scientific laboratory techniques and information to explore the biological…

A PATTERN OF PROBLEMS IN COMMUNICATION AMONG STUDENT COUNCIL MEMBERS AND BETWEEN THE COUNCIL AND ITS FACULTY ADVISORS CONTRIBUTED TO A DECISION TO SUBSTITUTE A PROGRAM OF SENSITIVITY TRAINING FOR THE USUAL STUDENT COUNCIL ORIENTATION PROGRAM. IT WAS HOPED THAT SUCH A PROGRAM WOULD FACILITATE A FLOW OF EXPRESSION AND A REDUCTION OF INTERPERSONAL…

As part of an experiment, a three quarter sequence in organic chemistry was designed to be accompanied by laboratory experiments that reinforce the lecture material and encourage independent investigation by minimizing cookbook-style procedures. By having laboratory techniques explained in detail on video casettes, students were exposed to uniform…

Instructional cross-media experiments are difficult to design because they involve complex instructional systems which include variables that are hard to control. Strict controls can be approached in the laboratory setting, but as the experimenter moves from the laboratory to the field study, especially in developing countries, concessions to…

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (CW)

Advocates using classic lectures in chemistry as guidelines for good teaching. Uses quotes from an 1848 book of lectures by John Scoffern to illustrate teaching principles relating to teacher enthusiasm, relevant materials, simple demonstrations, good laboratory experiences, nomenclature, and practical applications. (TW)

Describes the Mississippi Governor's School, an intensive three-week summer school for gifted high school students. Explains format of major courses, use of the American Chemical Society computer course in polymer chemistry, discussion sections, and hands-on laboratory. (JM)

An interdisciplinary physiology and pharmacology course presented by the Medical Interaction Laboratory at the University of Tennessee College of Veterinary Medicine provides interaction among faculty, conserves faculty time and animal expense, and presents a coordinated laboratory experience. (BH)

Discussed are experiments that may be done using a microcomputer to analyze scattering data. Apparatus assembly, procedures, and results for this activity are presented. (CW)

Reports on an attempt to bring about conceptual change in children's concept of speed by the teaching of the science of speed emphasizing an integrated hands-on experience. Reports that it may be possible to modify naive conceptions by teaching that targets particular concepts. (Author/YP)

Describes a microcomputer-based software package developed at the University of Surrey for teaching digital signal processing to undergraduate science and engineering students. Menu-driven software capabilities are explained, including demonstration of qualitative concepts and experimentation with quantitative data, and examples are given of…
