Provides instructions for and examples of balancing chemical equations using a desktop calculator. (JN)

Suggests alternatives for benzene, carbon tetrachloride, and chloroform and offers safety precautions when these solvents must be used. (JN)

Lists 13 producers/suppliers (including addresses) of computer programs in sciences, with brief comments related to chemistry. Also lists three periodicals and a book for pet microcomputer users. (JN)

Discusses Le Chatelier's Principle from a thermodynamic perspective and applies it to the effect of temperature on the solubility of gases in liquids. Rationale of this discussion is to evaluate data in a previous article claimed to be contradictory to the Principle. (Author/JN)

Describes a method for specifying R/S (clockwise/counterclockwise) configuration about a chiral center which does not require the use of a three-dimensional physical model, the mental visualization of the molecule, or the memorization of a recently reported arbitrary number system. (Author/JN)

Compares Schoenflies and Hermann-Mauguin notations of symmetry. Although the former (used by spectroscopists) and latter (used by crystallographers) both describe the same symmetry, there are distinct differences in the manner of description which may lead to confusion in correlating the two notations. (Author/JN)

Euler's theorem for homogenous functions is useful when developing thermodynamic distinction between extensive and intensive variables of state and when deriving the Gibbs-Duhem relation. Discusses Euler's theorem and thermodynamic applications. Includes six-step instructional strategy for introducing the material to students. (Author/JN)

Argues that science dominates our culture and has developed an institutional similarity to the religion which dominated earlier eras. Uses religion as a metaphor in advocating a scientific reformation in science instruction so it may be accessible to all and not the property of a few. (Author/JN)

Laboratory exercises from five chemistry curricula were examined to determine organization (integration of laboratory work with other parts of a course) and tasks required of students (assessed in terms of inquiry skills and behaviors required for the laboratory work). Implications and suggestions for instruction are included. (Author/JN)

Reports results of two-part survey on organization of chemical libraries at the college and departmental levels. Includes library configuration, size of collections, hours/service/staff, departmental reading rooms, and instruction in chemical literature based on questionnaires returned by 149 libraries and 144 department chairpersons. (JN)

Offers an instructional approach to increase students' ability to employ mathematical operations as a means of physical measurement. (Author/JN)

High test scores may measure general intelligence or test taking "savvy" rather than acquisition of knowledge of a particular subject. Pretests may help instructors differentiate between material students already know and good performance based on flaws in the wording of tests as indicated by pretests administered to college chemistry students.…

Presents guidelines for field trips to chemical industries. Includes examples of objectives, administrative aspects (time off from school, contact persons, transportation, pre/post-trip discussions, and guides at the industrial facility). Includes an evaluation of trips taken to industrial plants in Israel. (JN)

Describes apparatus/methodology and provides background information for an experiment demonstrating electrochemical concepts and properties of electrochemical cells. The color of a solution close to an electrode is changed from that of the bulk solution to either of two contrasting colors depending on whether the reaction is oxidation or…

Substantially self-paced programed learning at Sheffield City Polytechnic Metallurgy Department was found to be better than conventional lectures, provided that new topic areas covered were relatively small, as demonstrated by using inexpensive, simple instructional materials. (Author/JN)
