Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Introduces a photogate arrangement using a photo-reflective sensor for air track experiments. Reports that the sensitivity to sunlight can be eliminated and a mechanically more convenient package produced. Shows the mounting, circuit, and usage of the photogate. (YP)

Traces the evolution of instructional computing in the design and control courses. Discusses process design, process control, and expert systems. Concludes that the computing tools for undergraduate instruction are mostly in step with design and control practice in chemical engineering. (CW)

Describes a program to support lectures on analytical centrifugation, and to illustrate the manner in which useful analytical data about macromolecules can be obtained from simple centrifugation studies without the need for mathematical expertise. Discusses the background, methods, calculations, and results involved in this activity. (CW)

Discusses the role of the fruit fly in genetics research requiring a multidisciplinary approach. Describes embryological and genetic methods used in the experimental analysis of this organism. Outlines the use of Drosophila in the study of the development and function of the nervous system. (RT)

Describes three methods and their advantages and disadvantages for introducing genes into animals. Discusses the predictability and tissue-specificity of the injected genes. Outlines the applications of transgenic technology for studying gene expression, the early stages of mammalian development, mutations, and the molecular nature of chromosomes.…

Details a rationale for teacher shared information. Outlines possible content to include in such a network. Describes advantages and implications a database might have for teachers. (RT)

Reports on the evaluation of two programs which followed the master teacher training model espoused by the National Science Foundation, but used different types of master teachers and activities. Different results were produced from the two evaluation methods; using both methods provided a clearer view of the strengths and weaknesses of the…

Uses simple models to illustrate the principles of this genetic method of mapping gene loci. Stresses that this system enables a practical approach to be used with students who experience difficulty in understanding the concepts involved. (CW)

Discusses some of the barriers that impede minority success in college and gives suggestions for overcoming them. Describes the California Minority Engineering Program (MEP) as a successful program that has been replicated at several California universities. Presents the three structural elements and gives suggestions for starting a MEP program.…

Lists barriers that limit the recruitment of women from the existing pool of eligible women into engineering programs. Discusses several components that are important to successful recruitment of women. Uses the program at Purdue as a successful example. Suggests special steps for faculty and administrators to follow. (CW)

Describes a study of perceived difficulty of chemistry courses among secondary school and college students in Kenya. Concludes that organic chemistry may not be as difficult as many people believe. (CW)

Discusses some of the major research in science education published during the last 10 years in order to raise some of the methodological issues involved. Illustrates the progress that has been made along the path toward a science of teaching science. (CW)

Reports on a study conducted to determine whether a common relationship exists for faculty size in U.S. engineering colleges. Suggests that an index of normative loading can possibly be established. (RT)
