Discussion on the proper use of the chemistry terms "dissociation, hydrolysis, ionization, oxidation and reduction" is presented. (CP)

Discusses uses of programmable pocket electronic calculators in the secondary level classroom. Uses discussed include: grading, laboratory, exercises, computing T-scores, and a quantitative approach to chemical equilibrium. (SL)

Discusses how a chemistry teacher can help the student learn the technical vocabulary of chemistry. (MLH)

Discusses an explanation for secondary science students of the concept of additivity of oxidation and reduction potentials, especially in relation to the nonapplicability of Hess's Law. (MLH)

Presents questions and answers about the fluoridation of water regarding the compounds added to drinking water in the fluoridation process, how raw water is tested for fluoride content, and how fluoride reacts with tooth enamel. (CS)

Discusses a laboratory experiment in which uranium is isolated by the reduction of uranyl acetate. (MLH)

Describes the process of self-regulation, which Piaget hypothesizes governs all intellectual growth, and suggests a way in which homework problems in a chemistry course can be used to provide students with an opportunity for self-regulation. (MLH)

Discusses methods and exercises appropriate for use in a secondary school chemistry classroom to enhance mastery of skills in these three areas: communication, mathematics, and problem solving. (CS)

A discussion of problems students have with the concept of percent, with special emphasis on the use of percent in elementary chemistry. (BB)

Tries to clarify some apparent confusion surrounding the concept of atomic weights as presented in some chemistry textbooks. Another confusion is with the word thermometer, as it implies heat measurement. Suggests renaming it calorikinetic potentiometer, instead, to reflect what it does. (GA)

Reviews a game for teaching electronic structures of atoms. (SL)

Presents responses to an earlier report concerning a procedure for the derivation of the Ideal Gas Law from Charles', Boyle's, and other gas laws. Logic errors and solutions that work are discussed. (CS)

Describes methods for teaching the mole concept, including analogous calculations involving household objects, and the use of a cardboard wheel showing the interrelationships between moles, molecular weight, and the gaseous molar volume. (MLH)

Describes the construction of a simple beam model of the hydrogen atom. (SL)

Describes a card game that uses chemical symbol and number cards to represent chemical formulas. Also discusses an end-of-term review game that utilizes competing teams. (MLH)
