Describes a laboratory experience for upper-level science students that provides a hands-on approach to understanding the basics of experimental physiology. Students design an experiment to determine the relative importance of dilution of plasma proteins in the overall renal excretory response following volume expansion with intravenous saline.…

Perceptions of students in a Year 10 classroom were compared with those of their teacher at each of six schools with regard to the aims, regularity, conduct and assessment of laboratory work. Students in five of the schools had statistically different views from their teacher about the relative importance of 10 aims of laboratory work,…

Describes using a computer statistical software package called Minitab to model the sensitivity of several microbes to the disinfectant NaOCl (Clorox') using the Kirby-Bauer technique. Each group of students collects data from one microbe, conducts regression analyses, then chooses the best-fit model based on the highest r-values obtained.…

Describes the Connecticut Academic Performance Test (CAPT) and explains the reasons for a curriculum change. Introduces CAPT-style labs which require students to identify a problem, ask questions, develop a hypothesis, design and conduct an experiment, analyze data, and draw conclusions. (YDS)

Presents a set of hands-on, outdoor science experiments designed to teach elementary school students about animal adaptation. The experiments focus on: how color camouflage affects an insect population; how spiderlings find a home; and how chameleons camouflage themselves by changing color. (SM)

Presents a laboratory exercise on the capabilities of plants to ward off the insects that want to eat them. (ASK)

Explores the use of quantitative EEG in the detection of lies employing a special electrode cap and specialized video recording and audio equipment. The method offers the ability to decide when it can predict accurately and when it can predict with 100% accuracy. (JPS)

Discusses the advantages of an extended school year and block scheduling for science learning. (DDR)

Describes an early childhood educator's approach to teaching children about rain, rainbows, clouds, precipitation, the sun, air, and wind. Recommends ways to organize study topics and describes experiments that can help children better understand the different elements of weather. (MOK)

Presents a science experiment in which students test the buffering capacity of household products such as shampoo, hand lotion, fizzies candy, and cola. Lists the standards addressed in this experiment and gives an example of a student lab write-up. (YDS)

Discusses the demand for distance education opportunities in engineering and science and considers delivery methods for theoretical content and for laboratory work. Explains the Real-Time Internet Mediated Laboratory Experiments (RTIMLE) that use the World Wide Web, and suggests that RTIMLE may be most appropriate for students who already have…

Introduces the analysis of a river as an excellent way to teach geochemical techniques because of the relative ease of sample collection and speed of sample analysis. Focuses on the potential sources of sample contamination during sampling, filtering, and bottle cleaning processes, and reviews methods to reduce and detect contamination. Includes…

Outlines how a course in robotics can be taught at the undergraduate level with specific experiments that can be used for incremental learning in programming a mobile robot or by simulating the actions of a robot. Contains 14 references. (Author/ASK)

Describes a variation of typical introductory chemistry stoichiometry experiments in which the reaction is run in a modified 20-ounce plastic soda bottle. (WRM)

Examined the shift in the educational-research paradigm in Finland as seen in 335 doctoral dissertations. Early in the century, educational history was the dominant topic, but by the 1950s the experimental paradigm took over. By the 1980s, factor analysis was a very common research method. In the 1990s, qualitative analyses account for one-third…
