Examines the psychology of learning and its application to work in the laboratory. States that the working memory capacity of students is limited; therefore the amount of information they can process needs to be controlled and "recipe following" in the laboratory is perfectly reasonable. (RT)

We describe our experience in building a remote laboratory for teaching magnetic domains. Fulfilling the proposed on-line experiments, students can observe and study magnetization processes that are often difficult to explain with written material. It is proposed that networks of remotely accessible laboratories could be integrated in the Global…

Studies of protein function increasingly use multifaceted approaches that span disciplines including recombinant DNA technology, cell biology, and analytical biochemistry. These studies rely on sophisticated equipment and methodologies including confocal fluorescence microscopy, mass spectrometry, and X-ray crystallography that are beyond the…

Using cultured fibroblast cells, undergraduate students explore cell division and the responses of cultured cells to a variety of environmental changes. The students learn new research techniques and carry out a self-designed experiment. Through this project, students enhance their creative approach to scientific inquiry, learn time-management and…

The purpose of this study was to survey the quantity and quality of laboratory work conducted by Grade 11 and 12 biology students in British Columbia High Schools, to analyze student performance on laboratory based questions on Provincial examinations, and to examine the curriculum for recommended laboratory work. Examination and curriculum data…

Discussion of the botany lessons used at two schools points out the need for fifth and sixth grade students to be taught the principles of plant life through observations made at an experimental garden plot at the school. (ND)

This manometer is a modification of a design reported previously. It contains simplifications in the design of the manometer itself and in the associated electrical circuit. The apparatus is useful in the study of gas-phase reaction kinetics. (BB)

Reviews experiments performed in a mobile spectroscopy laboratory. (SL)

Describes the use of an interactive computer terminal for introductory laboratory experiments. (SL)

The goal of many colleges is to make the organic chemistry laboratory completely flameless by using electric heating equipment. Benefits of eliminating the Bunsen burner, electrical heating equipment and accessories, hazards remaining in flameless laboratories, and design standards related to laboratory liability are the major topic areas…

Describes an experiment combining qualitative and quantitative information from hydrogen nuclear magnetic resonance spectra. Reviews theory, discusses the experimental approach, and provides sample results. (JM)

Presents specific techniques for lectures and demonstrations in acoustics for deaf students. (SK)

Presents Part II of a description of a computer-oriented course on process control which has been offered at the University of Wisconsin for undergraduate students. Lecture topics and laboratory experiments are also included. (HM)

A modification of the Ames test for detecting carcinogens and mutagens using a strain of bacteria is described. A suggestion is given for checking the correctness of procedures by using particular hair dyes which have been shown to be mutogenic. (Author/SA)

Urges the use of plastinated specimens as an alternative to traditional dissection in biology classrooms. Suggests that plastinated biological specimens heighten student interest and enhance teaching. Interview responses of students, teachers, and administrators to the use of plastinated specimens in selected high schools were found to be very…
