A New "Bottom-Up" Framework for Teaching Chemical Bonding Tami Levy Nahum, Rachel Mamlok-Naaman, Avi Hofstein, and Leeor Kronik This article presents a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties. Levy Nahum, Tami; Mamlok-Naaman, Rachel; Hofstein, Avi; Kronik, Leeor. J. Chem. Educ. 2008, 85, 1680.

The Use of Molecular Modeling and VSEPR Theory in the Undergraduate Curriculum to Predict the Three-Dimensional Structure of Molecules Brian W. Pfennig and Richard L. Frock Despite the simplicity and elegance of the VSEPR model, however, students often have difficulty visualizing the three-dimensional shapes of molecules and learning the more subtle features of the model, such as the bond length and bond angle deviations from ideal geometry that accompany the presence of lone pair or multiple bond domains or that result from differences in the electronegativity of the bonded atoms, partial charges and molecular dipole moments, and site preferences in the trigonal bipyramidal electron geometry. Pfennig, Brian W.; Frock, Richard L. J. Chem. Educ. 1999, 76, 1018.

Effect of Experience on Retention and Elimination of Misconceptions about Molecular Structure and Bonding James P. Birk and Martha J. Kurtz A test designed to uncover misconceptions in molecular structure and bonding was administered to students from high school through graduate school and to some college faculty. The study tracked the disappearance of these misconceptions over a time span of 10 years of student experience, along with the development of accepted conceptions. Birk, James P.; Kurtz , Martha J.

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.
