An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

Galileo's discovery of the properties of pendulum motion depended on his adoption of the novel methodology of idealisation. Galileo's laws of pendulum motion could not be accepted until the empiricist methodological constraints placed on science by Aristotle, and by common sense, were overturned. As long as scientific claims were judged by how the…

As part of a first-year college Introductory Physics course, I have students construct an Excel[R]: spreadsheet based on the differential equation for pendulum motion (we take a pendulum having a light bar rather than a string, so it can go "over the top"). In extensive discussions with the students, I find that forcing them to make the…

The Kirby-Bauer method is regularly used to test bacterial susceptibility to antibiotics, and is often employed in the classroom for teaching this concept. In this exercise, additional materials and instructions were given to students for the preparation of garlic extract and loading on blank BBL paper discs. They were further instructed to test…

The objectives of this study are: (1) evaluation of the methodology used in recent search for particles with fractional electrical charge (quarks) and its implications for understanding the scientific research methodology of Millikan; (2) evaluation of 43 general physics textbooks and 11 laboratory manuals, with respect to the oil drop experiment,…

In honeybees, the proboscis extension response (PER) can be conditioned by associating an odor stimulus (CS) to a sucrose reward (US). Conditioned responses to the CS, which are acquired by most bees after a single CS-US pairing, disappear after repeated unrewarded presentations of the CS, a process called extinction. Extinction is usually thought…

In 1993 two of the authors of this article published a survey of introductory biology laboratory instruction in colleges and universities of the U.S. in order to document the status of laboratory instruction, and in particular, the use of inquiry based instruction. In this article, the authors present a survey that examined the changes that may…

The isolation and characterization of mutants has been crucial in understanding a number of processes in the field of cell biology. In this exercise, students examine the effects of mutations in the secretory pathway on protein localization. Yeast strains deficient for synthesis of histidinol dehydrogenase are transformed with a plasmid encoding a…

The way in which computer algebra systems, such as Maple, have made the study of physical problems of some considerable complexity accessible to mathematicians and scientists with modest computational skills is illustrated by solving the multiple pendulum problem. A solution is obtained for four pendulums with no restriction on the size of the…

Most biology students have the opportunity to look at protozoa under the microscopes or keep mealworms in a bowl. They may manipulate the heart rate of "Daphnia" or calculate the respiration of plants. They may even grow corn in the spring or keep fish and a small rodent or two. But once the class hamster grows testy from being awakened every…

Data from the Records Office of the University show that, over the period 1979-2003, Alemaya University trained and graduated a total of 492 students at Masters of Science degree level. The study also reveals that shortage of experienced and highly qualified resident national instructors, brain drain, scarcity of financial resources, lack of…

A. D. Mitchell's work on the phosphorus(I) reduction of the halogens and of mercury(II) and copper(II) chlorides is examined. A review of some salient characteristics of the Mitchell mechanism is presented, together with a discussion on how a student might benefit from a case study of the phosphorus(I) reduction of iodine or the similarly behaving…

A laboratory experiment reinforces the concept of acid-base equilibria while introducing a common application of spectrophotometry and can easily be completed within a standard four-hour laboratory period. It provides students with an opportunity to use advanced data analysis techniques like data smoothing and spectral deconvolution to…

This Education Policy Brief examines the research regarding the efforts occurring in the United States to consolidate school corporations or form cooperative agreements for shared services. The brief also examines those policy levers which are contributing to the elevated discussion concerning consolidation and shared services in Indiana. Based…

Managing the pedagogical aspects of the "computational turn" that is occurring within the Humanities in general and the disciplines associated with cognitive science and neuroscience in particular, first implies facing the challenge of introducing students to computation. This paper presents what has proven to be an efficient approach to bringing…
