Reviews emerging applications of microcomputers and hypermedia to assessment. Use consists mainly of computerized test administration of multiple-choice tests drawn from item banks. Significant advantages are possible in several areas including immediate feedback to students, formative evaluation with remediation possibilities, and monitoring…

A pharmacy student's suggestions for improving pharmaceutical education include increased emphasis on thinking skills in instruction and testing, incorporation of computer modules for independent study, a requirement that faculty periodically spend time in the field, review of laboratory experiments for relevance to practice, and improved…

Describes the process of osmosis from its discovery by Nollet in 1848 to modern applications. Uses experimental descriptions, illustrations, and photographs to explain osmosis. Discusses the technology of producing perfect filters and their applications in reverse osmosis to purify salt water and to filter blood in kidney machines. (PR)

Describes one individual's efforts to help support early science education by making presentations to children in elementary schools. Discusses the following aspects of the program: (1) getting started; (2) obtaining funding; (3) assessing students ability levels; and (4) deciding what hands-on experiences to give students. (MDH)

Suggests seven take-home experiments geared toward the topic of energy that can be utilized in large, general-education physics classes that do not include laboratory sessions. An appendix provides details for the experiment to measure the heat of fusion of water. (MDH)

This overview of the research process for the novice information retrieval (IR) researcher provides guidance on selecting a research question, choosing the type of test, defining variables, developing or using databases, finding and processing queries, assigning treatments to experimental units, collecting and analyzing the data, and presenting…

The issues, roles, dynamics, rationales and events embroiled in the dissection controversy are discussed. Insights into where the politics of biology education without speciesism or dissection are likely to take science education in the future are provided. (KR)

Examines features of science experiments that make them interesting to middle school students (n=59 seventh graders). Compared a model of interest in learning with the reasons students gave for liking experiments. Latent partition analysis was used to derive an empirical model from characteristics of interesting science experiments. (PR)

Discusses traditional school demonstrations and experiments in hydrotropism. Explains that these experiments seem to "prove" hydrotropism, but yet most botanists reject hydrotropism. Teachers continue to teach the concept because it is logical and the experiments are simple. (PR)

Presents activities that utilize piezoelectric film to familiarize students with fundamental principles of electricity. Describes classroom projects involving chemical sensors, microbalances, microphones, switches, infrared sensors, and power generation. (MDH)

Describes the use of Gowin's Vee to make the connection between lecture and laboratory, guide science fair research, help students decipher professional research journals, and make oral science fair or lab report presentations easier to understand. Provides examples of Gowin's Vee applied to research articles and comprehensive criteria for…

Explains how the surface of a freshly sliced potato can be used for a variety of enzyme action experiments including the influence of pH on enzyme action, the enzyme denaturation potential of boiling water, the inhibition of enzymes by heavy metals, and the effects of salt concentration on enzyme effectiveness. (PR)

A dynamic measure (number of examples needed to reach mastery) predicted transfer but not maintenance of a learned strategy for 64 third graders trained by scaffolded (n=32) or nonscaffolded (n=32) methods. A static measure had some predictive utility in the nonscaffolded condition. The potential superiority of scaffolded instruction is discussed.…

Describes changes in scientific research methods that have been brought about by the use of computers. Presents an example of the falling of a body in a fluid to show students how computers can be used to experiment with mathematical models and to automate experiments. Contains 11 references. (Author/WRM)

Describes a laboratory protocol using clinical veterinary data that teaches the cognitive, analytical, communication, and interpersonal skills necessary for students in a biology core laboratory course. (WRM)
