Describes research findings concerning children's difficulties with the concepts of circuit, current, and electrical energy. Discusses some possible approaches to instruction. (CW)

Examined is the contribution that hands-on, interactive centers can make to science education. The characteristics of informal and formal learning are compared and discussed. (KR)

Surveys British people over age 15 with the purpose of assessing the level of scientific knowledge among the public. Discusses the relationships between highest level of formal education, sex, and the answers given to questions. Illustrates how little school science instruction is remembered into adulthood. (CW)

Determined: (1) whether students thought of magnetic poles as exerting forces directly on electric charges and (2) the specific strategies students used to make predictions about the forces acting on electric charges in two problem situations. Implications for instruction are considered. (JN)

Discussed is a common error made by students in judging the distribution of the magnetic field of a circular loop along its diameter. Qualitative and quantitative explanations of the magnetic field distribution are presented. (CW)

Examined are the type of physics applications that students are interested in learning more about in school. Gender differences within that choice are explored. Interview methodology and the results of the interviews are discussed. (CW)

Described are the results of interviews of students regarding the concepts of "forced" and "natural" motion. Aristolean-like beliefs have been found to persist in students even though these views differ from orthodox physics views. (KR)

Described are the characteristics of the laser and its effects on the body. Discussed are examples of laser treatments, including angioplasty, ophthalmology, and dermatology. A discussion of lasers of clinical interest and their applications is presented. (YP)

Discussed are medical applications of ultrasound. The physics of the wave nature of ultrasound including its propagation and production, return by the body, spatial and contrast resolution, attenuation, image formation using pulsed echo ultrasound techniques, measurement of velocity and duplex scanning are described. (YP)

Models the ideas of children's misconceptions and subsequent acceptance of conventional scientific thought on the simple cusp of catastrophe theory. Demonstrates one theory of the forces which are necessary to change a misconception to a scientific concept. (CW)

Described are developments in medical electronics and physiological measurement. Discussed are electrocardiology, audiology, and urology as mature applications; applied potential tomography, magnetic stimulation of nerves, and laser Doppler flowmetry as new techniques; and optical sensors, ambulatory monitoring, and biosensors as future…

Discussed are technological advances applying computer techniques for image acquisition and processing, including digital radiography, computed tomography, and nuclear magnetic resonance imaging. Several diagrams and pictures showing the use of each technique are presented. (YP)

Discussed is a radionuclide imaging technique, including the gamma camera, image analysis computer, radiopharmaceuticals, and positron emission tomography. Several pictures showing the use of this technique are presented. (YP)

Summarizes current developments in alternative frameworks research in science education. Covers concept maps, learning as conceptual change, classroom strategies, problem solving in physics and where research should be going. (CW)

Describes three case studies of the use of the Learning in Science Project (Energy) in New Zealand. Themes discussed include systems undergoing change, defining initial and final conditions, energy as a nonmaterial factor of change, forms of energy and conservation of energy. Mentions other issues and research. (CW)
