Presents a literary review of the positions held concerning a central population issue, development within the ecosphere. Explores concerns posed by contemporary academic economists and ecologists. Suggests that demographers see the issue as an important area of research needing the expertise of several disciplines. (143 references) (MCO)

A sociometric rating scale and a measure of social problem-solving skills were administered to 61 Chinese kindergartners. In comparison to Canadian children examined in an earlier study, Chinese children were less accepting of each other, less prosocial, and more authority oriented in social problem solving. (BC)

Presents a hands-on mathematics task that can be investigated experimentally to produce a sequence of numbers. Describes ways to extrapolate values of the table of numbers by formulating and verifying a conjecture related to the pattern in the numbers. (MDH)

Introduces and discusses ideas and issues relevant to the international unification of scientific and technical information (STI) through development of an international aerospace database (IAD). Specific recommendations for improving the National Aeronautics and Space Administration Aerospace Database (NAD) and for implementing IAD are given.…

Through two surveys of nature and environmental centers throughout the United States, the author compares the centers' expressed goals with the goals of environmental education. These goals were determined by an accepted behavior model that is considered conducive to environmentally responsible behavior. (17 references) (MCO)

Discusses the first session and events from other sessions of a mathematics circle consisting of the author and four preschool children. Presents discussions that ensued with the children when asked to solve problems related to Piaget's stages of cognitive development. (MDH)

Early results from the Vermont Portfolio Project, which evaluated the progress of fourth and eighth graders in reading and mathematics using samples of student products, suggests that improvement is still needed in both subjects. Many factors will influence this pilot project's future direction, including availability of resources and development…

Reports on a study of the perceptions of 42 top- and middle-level administrators at 4 community colleges concerning the planning models and decision-making processes used at their college. Reports that both rural colleges relied on a consensus model, whereas the two urban colleges used autocracy and rational models respectively. (DMM)

Described is a mathematics resource laboratory where students use a variety of computer materials to enhance, reinforce, and broaden their concepts of first- and second-year algebra and geometry. Included are sample laboratory sheets and the answers. (KR)

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

The focus of this article is on how computer graphics can be integrated throughout the engineering graphics curriculum to increase visual perceptual skills. Visual perception is defined, the need to develop it is described, and methods which engineering graphics educators can use to develop it are outlined. (KR)

A paradigm that suggests the critical factor of quality rather than quantity of knowledge is proposed. The potential for retention and transfer in using a design and technology approach is discussed. Activities that generate relevant data for students are provided. (KR)

This review features new examples of using the computer relative to college-level mathematics to enhance pedagogy, solve problems, and model real-life situations. Included is a LOGO program that can be used to create and to stimulate subsequent investigations of spirolaterals, those figures generated by repeatedly drawing basic loops. (JJK)

Describes a new strategy for informing and involving people in environmental issues. Presents stories of successful efforts by ordinary people to effect environmental change. Suggests that these stories can provide the help people need to build more adequate models about environmental problems and about their roles in addressing them. (27…
