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.

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.

Why is the oxygen in water negative?  Liebman, Joel F.
Oxygen in water is negative because a negative charge, unlike a positive, can be stabilized using ground state ionic resonance structures.
