Analyzes the evolution of the French physics curricula and experiments from the beginning of the century to the present. Shows the strong coherence of the aspects of energy presented through teaching content and experiments. (DDR)

Compares the academic performance of students exposed to either "wet" practical classes or "simulated" practicals. Assessed practical write-ups from pharmacology students using a simulation showed a mark significantly better than those doing the "wet" practical. Simulations can provide an aid to learning which is as effective as "wet" practicals,…

Describes a classroom experiment that demonstrates under what conditions the parallel market rate approximates the free-market value of the domestic currency. Students act as foreign exchange traders in a developing country. Provides results of the experiment and discussion questions. (CMK)

Discusses the structure of a laboratory course that employs guided inquiry and collaborative learning to increase student preparedness for and intellectual engagement in laboratory investigations, and to give students an understanding and appreciation of a collaborative work environment. Contains 29 references. (DDR)

Describes different research activities that can be used in a college dining facility to make it a real-life laboratory where students can apply research skills and learn about the scientific method. Offers evidence that the experience provides an effective tool to teach the scientific method. (CMK)

Describes a science activity on polyploidy targeting middle and high school students which can be used to discuss topics such as chromosomes, cells, plant growth, and functions of stomates. Integrates mathematics in data collection. (Contains 13 references.) (YDS)

Describes absorption spectroscopy experiments that allow students to explore the mechanisms by which sunscreens and sunglasses provide protection from ultraviolet radiation. Exposes students to absorption phenomena in an engaging way. (DDR)

The theory that children's development of strategies-of-science experimentation is a consequence of developments in theory of mind was examined with 72 children in grades one, three, and five. Ability to predict, explain, and affect the reasoning of a doll or cartoon character predicted performance in planning controlled experiments and in…

Describes an ammeter that can be built for less than a dollar with commonly available parts to be used in circuits with 3-volt light bulbs. (WRM)

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes a simple, inexpensive modification that changes a brightfield microscope into a darkfield microscope, allowing low-contrast samples to be examined. (WRM)

Describes the construction and use of an inexpensive, portable photometer designed specifically for estimating population sizes in yeast cultures. Suggests activities for use with the photometer. (WRM)

Describes a short undergraduate course built entirely around a research trip to an astronomical observatory. (WRM)

Describes a review of research that addresses the effectiveness of simulations in promoting scientific discovery learning and the problems that learners may encounter when using discovery learning. (WRM)

The intent of this study was to investigate the impact of introducing computerized means, mainly simulation and the Internet, on teaching and learning electronics in Israeli high schools. Computers in electronics studies are, at the same time, part of the subject matter learned and a means for teaching and learning. Data were collected through…
