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)

Described are the purposes, laboratory set-ups, and procedures of four classroom experiments: ultrasound speedometer; vibrating-bar depth gauge; folding three-dimensional model of equipotential surfaces; and a simple optical system for the reconstruction of images from computer-generated holograms. Diagrams and pictures are provided. (YP)

Supercomputing is described in terms of computing power and abilities. The increase in availability of supercomputers for use in chemical calculations and modeling are reported. Efforts of the National Science Foundation and Cray Research are highlighted. (CW)

Described is a teacher education program organized by the Sea Education Association in Woods Hole (Massachusetts). The experience, including activities and examples of studies conducted, is discussed. Contact information for future cruises is included. (CW)

A computer assisted technology training program is described. Technological literacy is defined. A course list for the program and a programing model are provided. (CW)

Discusses four problems which concern engineering education in developing countries: (1) less value of handiwork; (2) lack of industrial culture; (3) low salary of faculty; and (4) cultural distortions. Describes three successful cases in Indonesia and Thailand. (YP)

Describes the development and courses of an annual nine-month professional training program in urban management. Evaluates the experience of the nine sessions organized for this program. (YP)

Discusses the various needs of chemistry classes in community colleges. Describes a tutorial package using computers. Reports the students' verbal evaluations and a drop in the dropout rate. (YP)

Reviews the objectives of laboratory work in chemistry education, current laboratory practice, and factors likely to impact on the nature of laboratory work in the future. Proposes that more investigation-style laboratory work be provided in order to foster the development of students' investigation skills. (Author/MKR)

Describes how a college teacher used Navajo traditional knowledge to rethink the teaching of college biology. Suggests that teachers intimidated by the intricate Dine Philosophy of Education may integrate Navajo knowledge into their courses through focused research guided by Navajo consultants. Includes five examples of redesigned curricula for…

Reports a study analyzing the perceptions of 45 college science majors regarding their formal precollege science experiences. Results suggest that college science majors generally hold science in higher regard than do noncollegiate adults; preferred science teachers who were enthusiastic, knowledgeable, friendly, inspirational, and fun; and…

Describes two library-lab exercises the authors have incorporated into their college chemistry course. The first exercise introduces students to scientific information and familiarizes them with the tools for accessing it. The second provides a framework for evaluating the reliability of that information and addresses the criteria that should be…

Discussed is the image of the engineer as seen through popular fiction and film. The effects of these recent comic cultural caricaturization images of engineers upon young men and women making career choices are described. (KR)

Described is a course designed to demonstrate the interactions of science, technology, and society and present effective ways to integrate science/technology/societal issues into the curriculum. Included are the course development, goals, content, selection criteria, project impact, course evaluation, and conclusion. (KR)

Presented is a discussion of the state of undergraduate education in science and engineering based on the interviews with a number of college students. Discussed are the underlying issues: recruitment, motivation, retention, curriculum, teaching incentives, role models and mentoring, hands-on experience, the nerd image, and quality of life. (KR)
