Significant information on the relative thickness of plutons, the structure of poorly exposed or concealed magnetic units, and possible evidence of mineralized ground are discussed. The techniques used to produce images that reveal the new information are described. A list of 34 references is included. (CW)

Presented is information about the National Science Teachers Association computer bulletin board, Science Line. Described are the features of the service and how teachers may gain access. (CW)

Outlines certain aspects of the Government's grants scheme that provides funds for information technology in schools. Discusses allocation of funds, National Council for Educational Technology involvement, how schools are using their grants, and meeting training needs. (JRH)

Surveys of (n=179) department chairs showed 47% of secondary science teachers did not use microcomputers during instruction, but 76% indicated microcomputers have had an impact on science laboratory activities in their school. Most frequent applications were simulations, graphing packages, and probes for collecting laboratory data. (17 references)…

Describes the powerful graphing ability of computer algebra systems (CAS) to create three-dimensional graphs or surface graphics of electric potentials. Provides equations along with examples of the printouts. Lists the programs Mathematica, Maple, Derive, Theorist, MathCad, and MATLAB as promising CAS systems. (MVL)

Provides an activity which measures the heat transfer through an insulated cylindrical tank, allowing the student to gain a better knowledge of both the physics involved and the working of spreadsheets. Provides both a spreadsheet solution and a maximum-minimum method of solution for the problem. (MVL)

Uses a TI-82 graphics calculator to model the air drag of plastic, wood, cork, and foam balls during projectiles experiments. Provides equations and typical data table. (MVL)

Describes the Macintosh equipment and software necessary to obtain and use digitized video for motion analysis. Also provides a simple strategy for undertaking such an analysis. (MVL)

Describes two laboratory exercises corresponding to studies of statics and dynamics to illustrate the concept that the combination of real and simulated laboratory tools, with some real data being recorded in computer-aided form, can result in a very sound understanding of physical principles. (JRH)

Discussed is the need for professors to be able to obtain updated reliable data regarding the professional requirements of their graduating students. The development and design of a theory that will establish a definitional system for skills and knowledge required for graduation is described. (KR)

Uses chaos theory to investigate the nonlinear phenomenon of population growth fluctuation. Illustrates the use of computers and computer programs to make calculations in a nonlinear difference equation system. (MDH)

Some commercially available software tools that have potential applications in the analytical chemistry curriculum are surveyed and evaluated. Tools for instruction, analysis and research, and courseware development are described. A list of the software packages, the compatible hardware, and the vendor's address is included. (KR)

Investigates the effects of both computer animations of microscopic chemical processes occurring in a galvanic cell and conceptual-change instruction based on chemical demonstrations on students' conceptions of current flow in electrolyte solutions. Finds that conceptual change instruction was effective at dispelling student misconceptions but…

Explains how the internet can be successfully used in science education by searching different web sites. Points out the dangers of the web such as accuracy of information, information overload, and availability of inappropriate materials. Recommends using web filters, instructing directions for internet searches, and using bookmarks. Uses…

Presents a list of World Wide Web sites that can help teachers with research assignments, curriculum boosters, and class activities. The sites include gateways to learning, mathematics references, social studies references, language arts references, and science references. Each listing includes the name, the Web address, and a brief description.…
