Discusses a visual database of information about chemical elements. Uses a single sided 12-inch, 30-minute, CAV-type videodisk. Contains a picture of almost every element in its stable form at room temperature and normal atmospheric pressure. Can be used with the video controller from "KC? Discoverer." (MVL)

Reported are the results of a 1987 survey of U.S. chemical engineering departments on health and safety. Some details of what is being done at the University of Alabama are provided. A syllabus and reading resources for a survey course on safety, health, environmental, and ethical issues are included. (MVL)

Described are the essential elements of memos; suggested are a basic format for organization, and two problems to which technical specialists' memos seem particularly susceptible. Included is a memo assignment used in senior design classes and professional development seminars. (MVL)

The main advantage of using these concepts lies in the reduction of algebraic work involved in solving certain dynamics problems. A brief analytical treatment of the acceleration center and a description of a virtual work principle for equipollent systems in the kinetics of rigid bodies are provided. (MVL)

Provided is a unit which relates the fulcrum of a lever system and the mean of a distribution of scores. The objective, rationale, two student laboratories, and an evaluation system are outlined. Content background on statistics is offered. (MVL)

Investigated is the impact on attitudes of prospective elementary school teachers of pragmatic, success-oriented courses in science as prerequisites for entry into science methods courses. A need for exposing prospective teachers to instructional strategies and experiences which are consistent with teaching practices and curricula employed in a…

Reviews three software packages: 1) a package containing 68 programs covering general topics in chemistry; 2) a package dealing with acid-base titration curves and allows for variables to be changed; 3) a chemistry tutorial and drill package. (MVL)

Stresses the need for chemical engineering education to keep abreast of current needs. Explores the need for global economics, marketing strategy, product differentiation, and patent law in the curriculum. Questions the abilities of current chemical engineering graduate students in those areas. (MVL)

Describes a program that enables students to apply their lecture and laboratory knowledge to practical situations in order to make a more informed career choice. Explains the three types of programs, student responses, and faculty involvement. Reports on the outcomes of the program. (RT)

Describes a lab exercise used to demonstrate the measurement of biomass in a three layered forest. Discusses sampling, estimation methods, and the analysis of results. Presents an example of a summary sheet for this activity. (CW)

Discusses the use of graph theory to aid in the depiction of organic molecular structures. Gives a historical perspective of graph theory and explains graph theory terminology with organic examples. Lists applications of graph theory to current research projects. (ML)

Traces the development of bonding theory and notes the influence of preconceived theory upon this development. Considers ideas of alchemy, Newton, Dalton, Lewis, and quantum mechanics. Suggests a move away from conservative descriptive approaches of bonding theory. (ML)

Described is German involvement in the UNESCO program for environmental education. Environmental awareness education in primary and secondary schools, universities, and professional training are discussed. Media participation is recognized. Current main developments are highlighted. (CW)

Describes an introductory biology course designed to enhanced the science learning of elementary education majors. A consideration of students' learning styles and interests combined with a belief that science academic talent is not a selective process, resulted in a biology course that was academically challenging and enjoyable for students. (ZWH)

Diverts from the traditional approach to teaching ecology and moves toward a more interdisciplinary approach by engaging students in a field trip to the Rocky Mountains. Using examples and insights, the author describes and identifies opportunities for promoting knowledge, understanding, and awareness of the environment and its surroundings. (ZWH)
