Presented are a list of topics and references for a course in which scientific theories and concepts are developed to explain the energy crisis. Using the suggested approach, students gain an understanding of scientific theories and concepts as they relate to current human problems. (DS)

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

The Springs task, an individually administered measure of ability to criticize and control experiments, is described. The task has characteristics similar to Inhelder and Piaget's Bending Rods task; it yields scores on naming variables, controlling variables, and analyzing experiments. (See also RIE: ED 163 092.) (JKS)

The development of earth and gravity concepts among 250 schoolchildren ages 8, 10 and 12 from two regions of Nepal was investigated. The children studied five nations located in different parts of the world. (HM)

These activities focus on the unifying concept of faster-moving fluids lowering fluid pressure. Students are able to visualize and measure the dynamics of fluid pressure with the hands-on approach of these activities, which helps to develop conceptual understanding. Activities are organized to show many examples of the same concept to reveal…

Multimedia technology is an invaluable teaching and learning resource. One advantage of technology based education is the ability to combine practical applications, visualization of complex mathematical and abstract subjects, virtual labs, and guided use of simulation software. This article describes several multimedia tutorials for…

To determine if different levels of graphic presentation affected understanding, 131 middle school science students with high and low spatial ability were shown programs teaching concepts of molecular diffusion with no graphics, static graphics, or animated graphics. Students with low spatial ability benefited from animated presentations. Spatial…

Describes a program where teams of fifth graders and high school junior and senior physics students work together to explore physical science principles and create a student-constructed exploratorium. Incorporates and synthesizes scientific inquiry, hands-on activities, and creative and critical problem-solving approaches in a motivating and fun…

The Multimedia Education Laboratory of the Chemical Engineering Department at the University of Michigan develops multimedia-based educational materials presenting difficult concepts and chemical engineering processes. Highlights include software developed for undergraduate courses; the Multimedia Encyclopedia of Chemical Engineering Equipment;…

Investigates changes in preservice teachers' conceptions about projectile motion brought about by a combination of reading and demonstration and appeal to usefulness. Results indicate the effectiveness of a combined Demo-Text condition on immediate posttests and effectiveness of text in producing long-term change. Analysis also indicates an…

Presents a visual aid designed to generate an image of water movement among soil particles using an overhead projector to teach the physical phenomena related to water status and water movement in the soil. Utilizes a base plate of thin transparent plastic, opaque plastic sheets, a plate of glass, and a colored aqueous solution. (AIM)

Describes a study of 32 University of Transkei (South Africa) freshmen's conceptualization of "limiting reagent," a basic concept in chemistry, based on student responses to two written test questions and clinical interviews. Results indicated that a high percentage of students had misconceptions and could not apply the concept…

Argues that science may be presented as a continuing effort to improve existing knowledge. Analyzes a three-month discourse by sixth graders, showing that the basic commitments enabling scientific progress can be realized in elementary schools. Suggests that people need to be able to move freely between scientific and other modes of thought to be…

Presented are nine physics demonstrations. Topics include mechanics, magnetism, mass, optics, friction, and molecular motion. An illustration and questions are included for each. (CW)

Discussed is the philosophy of the educational purpose of science education, the science involved, and the relationships of students and learning and students and content. A list of 14 references is included. (CW)
