Describes a placement test in general chemistry containing two paper-and-pencil Piagetian tasks. Results for 885 students accounted for only 21 percent of the criterion variable (predicted grade); suggest various reasons for this low correlation. (MLH)

Presents short questions and answers on biochemical topics, such as respiration, enzymatic reactions, symbiotic relationships, and oxygen consumption of sea animals. (MLH)

Describes an experiment in which the iodonation of aniline reaction is shown to undergo catalysis in solution of sodium lauryl sulfate which forms micelles with negatively charged pseudo surfaces. (MLH)

Describes a unified experiment in which an optically transparent thin layer electrode is used to illustrate the techniques of thin layer electrochemistry, cyclic voltammetry, controlled potential coulometry, and spectroelectrochemistry. (MLH)

Describes an instructional approach for teaching the cause-and-effect relationship between the qualities of atoms and the properties of their chemical compositions. Discusses atomic structure, ionization energies, homonuclear and heteronuclear bonding, and bond dissociation. (MLH)

Presents a set of rules for determining reaction orders of reacting species from the shape of a plot of the log of the pseudo-xth-order rate constants versus the log of the concentration being varied. (MLH)

Describes a community chemistry course for children aged 10-13 which emphasizes the recording of experimental observations in lab notebooks and the use of experiments that require few directions. (MLH)

Describes an advanced undergraduate experiment in which the stepwise stability constants of hi(II)-cysteine chelate are determined. (MLH)

Describes an experiment in which ph values serve as a basis for separating the acidic aspirin from phenacetin and caffeine on an ion-exchange column. (MLH)

This study designed the Environmental Chemistry Value Preference (ECVP) instrument to assess the value preferences of college non-science majors with respect to certain aspects of environmental chemistry and used the instrument to obtain the value preferences of various groups of non-science majors who had completed some chemistry courses. (BT)

Discusses statistics resulting from a report on female professors, associate professors, and assistant professors, on the faculties of Ph.D. - granting chemistry departments during the 1974-75 years. (MLH)

Described is a three-level self paced high school chemistry course developed for Queensland, Australia schools. The design involves a modification of the Keller Method. A sample unit test is included. (SL)

Described is the development of science courses for Australian secondary colleges. Included are synopses and course content for all units of physics, chemistry, geology, agriculture, astronomy and biology which have been developed to date. (SL)

Discusses the prominent American chemists of the nineteenth century and the way in which contemporary European science influenced them. (MLH)

Describes a computer program that allows the numerical solution of an acid-base equilibrium polynomial equation without the need for chemical approximations. (MLH)
