Science has many explanatory concepts that have been proposed to account for the observable features of things. Such explanatory concepts often have associated with them hidden or unseen "theoretical entities." The electron is a key concept in understanding phenomena described by science. The question arises, however, as to how students…

This report is part of an annual national survey that examines salaries of full-time teaching faculty in 54 selected academic disciplines. Data for the study were collected from a total of 296 public and 390 private four-year institutions from the baseline year of 1996-97 to the trend year of 1999-2000. This portion of the study covers salary data…

This study examined salary data for 8,270 college faculty in the field of chemistry for both public and private institutions for the years 1995-1996 and 1998-1999. The study reflects data obtained from the 279 public and 386 private institutions that participated in both study years. The study found that the average faculty salary in chemistry for…

Chemical change is a central theme of Chemistry which has itself been called the central science. This was the title of a popular American text book. I am thus putting forward the idea that chemical change is an idea central to science as a whole, so that it would be one of the ideas children should understand clearly whilst at school. This is…

Discusses the development of single concept or skill laboratory investigations in an inservice summer workshop and their successful use in the classroom. Included are two examples, respectively, relating to operation of a triple beam balance and classification of phases of matter. (CC)

Describes the philosophical background and operational procedures of an alternating and an experimental cooperative education program conducted, respectively, among undergraduate and graduate students. (CC)

Describes an experiment which yields low-volatility phenylacetylene, and suggests the use of the liquid product to examine alkyne chemical reactivity in organic chemistry courses. (CC)

Discusses the features of a course which emphasizes training of scientists and engineers with broad interdisciplinary knowledge in addition to those with a highly specialized professional preparation. Included is a list of books relating to applications of materials science concepts in general chemistry. (CC)

Reorganization of Agricultural Research Service is under way, triggered by charges that research hasn't kept pace with resource depletion and high cost of farming. A fight is predicted over the 1887 Hatch Act funds ($221 million appropriated by Congress in 1981). Comments on the situation by various individuals are included. (Author/JN)

Suggests uses for and possible adaptations of a set of semiflexible molecular models. Includes price and supplier information. Also suggests rubbing oil from human face/hands along the pouring lip of a beaker, allowing one to pour uniformly from the beaker spout and making the process as dripless as possible. (Author/JN)
