Reviews Piaget's theories and the teaching of chemistry. (SL)

Presents a simple method for deriving steady state rate equations for first-order and pseudo-first-order reactions. (SL)

Points out that equilibrium binding and steady-state enzyme kinetics have a great deal in common and that related equations and error analysis can be cast in identical forms. Emphasizes that if one type of problem solution is taught, the other is also taught. Various methods of data analysis are evaluated. (JM)

Acceptable answers are provided for two chemistry questions. The first question is related to the prediction of the appearance of non-first-order proton nuclear magnetic resonance (NMR) spectra. The second question is related to extraterrestrial kinetic theory of gases. (JN)

Discusses a set of relations (addressing changes in volume and refractivity) for use in the study of binary systems. Suggests including such an experiment in undergraduate physical chemistry courses (measuring density/refractive index of pure compounds and their mixtures) to predict even small changes occurring during mixing process. (Author/JN)

The increased emphasis on theory in undergraduate/introductory chemistry courses suggests a need for beginning students to understand philosophic aspects of scientific theory. Discusses alternative viewpoints on theory development and how misapprehensions about this can influence student creativity; argues for formal introduction to theory…

Summarizes the ideas of Sir Robert Robinson and Sir C. K. Ingold that contributed to the controversy in developing the electronic theory of organic reactions. (CS)

Designed for the organic chemist involved in interpreting NMR spectra, basic concepts of chemical shift equivalence and magnetic equivalence in NMR spectrometry are discussed. (CS)

Presents the selection rules for all four quantum numbers of the hydrogen atom and for a linear harmonic oscillator. Suggests that these rules deserve special mention in an elementary course of quantum chemistry. (Author/JN)

Presents selected position papers and research papers influenced by the work of Jean Piaget, intended to help science educators understand Piaget's work and how it applies to science education. Emphasis on formal reasoning stage of development. (SA)

Deliniates five formulas that are needed to compute a part of several formulas of a reducible representation in spherical symmetry. (SA)

The neglect of neutrino emission during nuclear beta decay in many general chemistry textbooks is discussed. (BB)

Investigates whether introductory college chemistry students today differ from those a generation ago in terms of Piagetian cognitive functioning, aptitude, and achievement, and whether the gender differences in Piagetian cognitive development functioning found in 1981 are still evident today. Suggests that today's students are different in a…
