Examining Quantum Oddities within the Context of Other Major Scientific Theories Pablo A. Molina
This article presents an epistemological discussion on the conceptual hurdles shared by quantum theory and evolution, gravity, and special relativity, and offers students a logical structure to deal with waveparticle duality, the uncertainty principle, boundary conditions, and the quantization of energy.

The Ubiquitous Metaphors of Chemistry Teaching Herbert Beall
The understanding and the confusion resulting from any scientific metaphor thus have to be considered when it is used. For example, a common chemical metaphor for the electron distribution about an atom is a cloud. Some of the entailments of this metaphor are apt, such as the diffuse nature of a cloud. Others, such as the ability of a cloud to evaporate, are not appropriate.

Teaching Chemistry with Electron Density Models Gwendolyn P. Shusterman and Alan J. Shusterman
This article describes a powerful new method for teaching students about electronic structure and its relevance to chemical phenomena. This method, developed and used for several years in general chemistry and organic chemistry courses, relies on computer-generated three-dimensional models of electron density distributions.

Concept Maps in Chemistry Education Alberto Regis, Pier Giorgio Albertazzi, Ezio Roletto
This article presents and illustrates a proposed application of concept maps in chemistry teaching in high schools. Three examples of the use of concept maps in chemistry teaching are reported and discussed with reference to: atomic structure, oxidation-reduction and thermodynamics.

On a Relation between the Heisenberg and deBroglie Principles Ludwig, Oliver G.
Author suggests a way of looking at the wave-particle duality with a more concrete application of both relations and an insightful interpretation of the deBroglie principle for use in general chemistry.

Teaching the shapes of the hydrogenlike and hybrid atomic orbitals Allendoerfer, Robert D.
The purpose of this article to show that, in this age of computer graphics, the "difficult to obtain" argument no longer has merit and to give an example of where the standard treatment gives insufficient attention to detail in describing the nodal surfaces of hybrid orbitals.

How does the electron cross the node? Johnsen, Russell H.; Lloyd, Winston D.
Confusion arises from the assumption that the electron is a particle, when the model that produces an orbital diagram assumes that the electron behaves as a wave.

Nuclear concepts as part of the undergraduate chemistry curriculum Caretto, A. A., Jr.; Sugihara, T. T.
It is proposed that there are distinct advantages to a freshman curriculum that introduces nuclear concepts simultaneously with the discussion of analogous atomic and molecular concepts.
