Dr. Mark Ott, a professor at Jackson Community College in Wyoming, has created a set of compelling screencasts and accompanying audio tracks that are designed to complement his general chemistry lectures. Visitors can look over these materials at their leisure, and they will find very well-thought out lessons that cover such topics as unit conversion, molecular formulae, balancing chemical equations, and ionic and covalent bonding. All of these materials are lucid and might be used both by students who are becoming more acquainted with the world of chemistry, or by educators who might be seeking to assist their students in the learning process. These learning modules are available here in either the Flash format or via Google video.
