The purpose of the current study is to explore the impact of associating animations with concrete models on eleventh-grade students' comprehension of different visual representations in organic chemistry. The study used a post-test control group quasi-experimental design. The experimental group (N = 28) used concrete models, submicroscopic…

In this study, we investigated whether the understanding of the particulate nature of matter by students was improved by allowing them to design and evaluate molecular animations of chemical phenomena. We developed Chemation, a learner-centered animation tool, to allow seventh-grade students to construct flipbook-like simple animations to show…

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 exercise integrates the infrared unknown identification ("IR-ID") experiment common to most organic laboratory syllabi with computer molecular modeling. In this modification students are still required to identify unknown compounds from their IR spectra, but must additionally match some of the absorptions with computed frequencies they…

The ability to design and to aspire of the future design of three-dimensional molecular animations to teach molecular symmetry is an exciting outcome of computer-driven technologies. Some of the details and vital issues addressed in developing a set of Web pages to teach molecular symmetry at Imperial College London using crafted animations are…

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.
