Conducted an ethnography to evaluate the usefulness of the notion of community of practice in classroom settings. Documents how collectively available knowledge of a classroom community was transformed as resources and practices were adopted by more and more members. Discusses implications for the organization of classroom environments that…

Discusses design of microcomputer workstations for children. Dimensions for seating and worksurface are suggested for ages 6-8 and 9-11, and these dimensions are compared to adult standards. Several drawings and tables are used to present the design specifications. (nine references) (MES)

Introduces and develops mathematical notation to assist undergraduate students in overcoming conceptual difficulties involving the underlying mathematics of state functions, which tend to be different from functions encountered by students in previous mathematical courses, because of the need to manipulate special types of partial derivatives and…

Describes the challenge to human eyesight brought about by the growing use of computers. The characteristics of the computer monitor and the "eye posture" required by monitors is discussed. Glasses appropriate for computer viewing and steps computer users can take to reduce eyestrain are covered. (KRN)

Some considerations and proposals are introduced to improve the efficiency of information management training based on the results of experiments done in this field. The integration of different parts of the information training program into scientific and technical specialties curricula is discussed. (KR)

Described is a practice-oriented master's program (Executive Master of Science in Engineering) based on the premise that the successful management of modern technology requires a broadening of executive knowledge, skills, and perspectives. A description of the curriculum and program status are included. (KR)

Contends that the level of safety built into roads is largely unpremeditated and that roads and highways are not as safe as they might be. Discusses practices, standards, and deficiencies in highway and traffic safety related to geometric design and traffic engineering. Recommends increased transportation engineering professionalism and public…

The integration of scientific and technical perspectives on modern life with the insights and understanding derived from such studies as philosophy, economics, and literature is described. The historic and aesthetic elements of technology and engineering are discussed. (KR)

Swiss engineering education is detailed and the roles of public enterprise, society, industry, and the engineering profession are illustrated. Educational issues are discussed in an international context. (CW)

Describes the existing educational structure in Brazil dedicated to the training of engineers and engineering technologists. (PR)

Presents an exercise that describes the direct extraction and purification of DNA from a small soil sample. Also discusses the subsequent amplification of a 343-bp Tn7 transposate A gene fragment (tnsA) from a strain of Pseudomonas aureofaciens 3732RNL11. Contains 21 references. (DDR)

Explains a novel way of approaching centripetal force: theory is used to predict an orbital period at which a toy train will topple from a circular track. The demonstration has elements of prediction (a criterion for a good model) and suspense (a criterion for a good demonstration). The demonstration proved useful in undergraduate physics and…

Investigates what two teachers learn from each other as they engage in the three-month coteaching of an engineering curriculum to Grades four and five. Provides direct and indirect evidence of teachers' knowledgability. Contains 34 references. (DDR)

A survey of 260 secondary and 251 postsecondary business educators found the former more likely to think computer ergonomic techniques should taught in elementary school and to address the hazards of improper use. Both groups stated that over half of students they observe do not use good techniques and agreed that students need continual…

Describes courses designed to complement mainstream technical graphics courses in architectural and mechanical graphics. Vocational track students and precollege students mainly benefit from these courses. Contains 23 references. (DDR)
