Abstract
This paper addresses our approach to teaching organic chemistry and introduces the application of highest occupied and lowest unoccupied molecular orbitals (HOMOs and LUMOs) in animated form. This teaching approach allows students to (i) picture the reaction process in three dimensions, (ii) better understand why a reaction occurs by noting electron-rich and electron-poor centers, (iii) see steric arguments in competing reactions, (iv) observe electron flow from the nucleophile into the electrophile, (v) gain a better understanding of resonance and hyperconjugation, and (vi) gain an appreciation for semiempirical and ab initio calculations.

Transition-Structure Catalog of Organic Reactions
Daniel H. EssJournal of Chemical Education2012 89 (6), 817-818Transition-Structure Catalog of Organic Reactions
Daniel H. EssJournal of Chemical Education2012 89 (6), 817-818Modern organic chemistry textbooks contain qualitative Lewis-structure drawings of transition structures. Missing from these drawings are estimates of partial bond lengths. A catalog of accurate density functional ground and transition structures for ...
Visualization Tools for Organic Chemistry
Jennifer L. MuzykaJournal of Chemical Education2009 86 (2), 254Visualization Tools for Organic Chemistry
Jennifer L. MuzykaJournal of Chemical Education2009 86 (2), 254These interactive displays of molecules, animations, and text target topics that students have difficulty visualizing, including conformations of alkanes and cycloalkanes, stereochemistry, and several reactions (SN1, SN2, E1, and E2).
A Simple and Easy-To-Learn Chart of the Main Classes of Inorganic Compounds and Their Acid-Base Reactions
Grigoriy SeredaJournal of Chemical Education2005 82 (11), 1645A Simple and Easy-To-Learn Chart of the Main Classes of Inorganic Compounds and Their Acid-Base Reactions
Grigoriy SeredaJournal of Chemical Education2005 82 (11), 1645A two-dimensional chart for the classification of the main classes of inorganic compounds is presented. This presentation takes advantage of the visual memory of high school students in learning the relationship between acidic and basic properties of ...

Using Computer-Based Visualization Strategies to Improve Students' Understanding of Molecular Polarity and Miscibility
Michael J. Sanger and Steven M. Badger IIJournal of Chemical Education2001 78 (10), 1412Using Computer-Based Visualization Strategies to Improve Students' Understanding of Molecular Polarity and Miscibility
Michael J. Sanger and Steven M. Badger IIJournal of Chemical Education2001 78 (10), 1412This study reports how instruction including visualization strategies associated with computer animations and electron density plots affected students' conceptual understanding of two chemistry topics. Two sets of students responded to several conceptual ...
