The aim of this study was to develop molecular genetics inquiry programs using the "eyes absent" gene of "Drosophila melanogaster." The program was composed of various molecular genetics experiments, including mutation observation, cross-breeding, searching for genetic information in web databases, gDNA extraction, and PCR.…

A national survey on chemistry instructional laboratories was administered to faculty members at four-year postsecondary institutions in the United States for the purpose of exploring levels of inquiry-based instruction implemented in laboratory courses. Respondents were asked to rate the level of choice their students had in deciding six key…

Molecular cloning skills are an essential component of biological research, yet students often do not receive this training during their undergraduate studies. This can be attributed to the complexities of the cloning process, which may require many weeks of progressive design and experimentation. To address this issue, we incorporated an…

Purpose: Owing to the specialist nature of biological experimentation, scientific research staff have been largely neglected from the pro-environmental initiatives which have inundated other areas of higher education. This dearth of studies is surprising given that scientific research is recognised as a substantial contributor to the environmental…

The central complex is a prominent structure in the "Drosophila" brain. Visual learning experiments in the flight simulator, with flies with genetically altered brains, revealed that two groups of horizontal neurons in one of its substructures, the fan-shaped body, were required for "Drosophila" visual pattern memory. However,…

In this article the problems of functioning algorithms development for system of the automated analysis of educational process rhythm in a higher educational institution are considered. Using the device of experiment planning for conducting the scientific researches, adapted methodologies, received by authors in the dissertational works at the…

The simplest age-structured population models update a population vector via multiplication by a matrix. These linear models offer an opportunity to introduce mathematical modeling to students of limited mathematical sophistication and background. We begin with a detailed discussion of mathematical modeling, particularly in a biological context.…

The effects of impeller size, agitation and aeration on the rate of yeast growth were investigated using bench-top bioreactors. This exercise, carried out over a six-month period, served as an effective demonstration of the importance of different operating parameters on cell growth and provided a means of determining the optimisation conditions…

Describes an organic chemistry experiment for teaching the basic concepts of chemical kinetics. Provides background information about first- and second-order reactions, experimental procedures of the Diels-Alder reaction between cyclopentadiene and dimethyl fumarate, and the experimental results. (YP)

Describes experimental procedures to produce magnetic fields with a thermocouple. Provides diagrams showing the apparatus, tables of experiment data, and background information on the theory. (YP)

A compilation of essays deals with two vital ethical issues: (1) in such matters as genetic research, human subject research, and behavior modification, the conflict between freedom in scientific research and protection of the immediate public; and (2) the question of whether ethical guidelines have to be developed for teachers, or academic…

Describes an experiment for advanced-level undergraduate students for extending student experiences involving recording and interpreting infrared (IR) and nuclear magnetic resonance (NMR) spectra from reactions of organometallic compounds. Experimental procedures, analyses and structural assignments, and suggestions for extension and modification…

This paper attempts to promote an understanding of physics through its history and replication of the oscillation experiments of Isaac Newton and Daniel Bernoulli from the 17th and 18th centuries. The experiments described can be treated at a level of sophistication to suit the interests and capabilities of the student. Reproductions in the…

Describes an undergraduate biochemistry laboratory experiment on enzyme kinetics using the D-amino acid oxidase system and an ammonia electrode. Preparation of an ammonia standard curve, a sample preparation, and inhibition studies are discussed. (YP)

Presented is a discussion of the events of the 20-year lapse between the invention of the pile in 1800 by Volta, and Hans Christian Oersted's famous definitive paper "Effects of a Current of Electricity on the Magnetic Needle." Students are thus enabled to appreciate the climate of the time and the manner and significance of Oersted's…
