An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that,…

This article summarizes an investigation into how Flash-based cartoon video tutorials featuring molecular visualizations affect students' mental models of acetic acid and hydrochloric acid solutions and how the acids respond when tested for electrical conductance. Variation theory served as the theoretical framework for examining how students…

The authors have developed a computer-based learning module on the unit cell of various types of crystal. The module has two components: the virtual unit cell (VUC) part and the subsequent unit cell hunter part. The VUC is a virtual reality simulation for students to actively arrive at the unit cell from exploring, from a broad view, the crystal…

By comparing two-dimensional (2D) chemical animations designed for computer's desktop with three-dimensional (3D) chemical animations designed for the full immersive virtual reality environment CAVE[TM] we studied how virtual reality environments could raise student's interest and motivation for learning. By using the 3ds max[TM], we can visualize…

This new WebWare combines instructional text and Jmol interactive, animated illustrations that help students visualize the mechanism. It is concluded that by animating the fluxional behavior of a simple model for chiral metal catalyst Sn(amidinate)[subscript 2], in which axial/equatorial exchange within the amidinate rings occurs through a Berry…

Provides a series of short articles about various uses of computers and courseware in teaching chemistry. Addresses topics such as a programming utility for animation, an organic synthesis program, a program for the allocation of organic qualitative analysis of unknowns, color images of molecules, and enhancing spreadsheet capabilities.
