As one of the efforts related to closing the gap between the growing demands for clinical laboratory workers and the supply of well-trained workers, the volume and quality of laboratory procedures and the general characteristics of workers in North Carolina hospitals were studied. Approaches to the study included tests on "unknowns" by…

Describes a technique used extensively in the chemical industry to find and control unanticipated safety hazards. Discusses how a team of individuals can consider how equipment or processes operate and deviations from normal conditions. Suggests this technique could be used in educational laboratories. (TW)

Introduced is a unique generation method of Fourier series requiring simple mathematical skills and using computer programs. Discusses Fourier synthesis by microcomputer, and Fourier analysis with simple equipment. Shown are a circuit diagram, computer programs, monitor displays and tables of data. (YP)

Describes a spectrophotometric titration experiment which uses a manual titration spectrophotometer and manually operated buret, rather than special instrumentation. Identifies the equipment, materials, and procedures needed for the completion of the experiment. Recommends the use of this experiment in introductory quantitative analysis…

Developed by classroom teachers during the development phase of Minnesota's Graduation Standards, this performance package is made up of locally designed assignments that, taken together, show whether a student has learned and can apply the knowledge and skills related to comprehending technical information from documents or electronic media and…

The emphasis on laboratory activities for science students has increased. This paper describes research that sought to determine which laboratory skills and competencies are viewed by current teachers as necessary for the preservice teacher to develop. The skills and competencies survey included 145 items in three categories (general, biological…

Discusses the language laboratory as a means of developing practical abilities in a foreign language. Two topics are treated specifically: (1) the laboratory from a technical and theoretical perspective, and (2) an analysis of the language skills most effectively trained through use of the language laboratory. (AMH)

A change in language laboratory use at the University of North Alabama has given new meaning to the lab requirement and role. While developing a language program, the developer reviewed the language lab's traditional role and found a mixed history with many negative aspects. Personal experience also revealed problems, including: students and…

Describes techniques and equipment intended to both improve laboratory measurements and also form a background for more advanced work by introducing the concepts of electronic and digital circuits. (GS)

Describes an undergraduate laboratory experiment in which the position of the double bond in an alkene is determined by identifying its ozonolysis products. This experiment can also be used to introduce the technique of gas chromatography. (MLH)

Describes an undergraduate organic chemistry laboratory experiment which utilizes the Gabriel Synthesis to demonstrate the acidity of imides and to provide an example of nucleophilic substitution reactions. The experiment also demonstrates the laboratory techniques involved in simple and steam distillation, filtration, extraction, and…

Describes a laboratory experiment that begins with a discussion of the fermentation process, the steps of winemaking, the types of wines that can be produced, and the differences between wines. Outlines the procedure for making red wine in the laboratory and describes other types of wine that can be produced. (GS)

Describes how to construct an isothermal calorimeter and lists typical results of a displacement reaction using zinc. (LS)

Describes features of agglutinin research utilizing the jack bean and suggests similar experiments for biology students that utilize more familiar plants. (LS)

Describes some of the problems likely to be encountered by British science teachers and school science departments in the implementation of laboratory standards under the Health and Safety at Work etc. Act 1974. (MLH)
