Enhancing instructions using interactive multimedia simulations

In this paper, simulations to enhance learning and retention in a course in Civil Engineering (Soil Mechanics) are presented. One type of simulation deals with the delivery of course content to better elucidate on selected basic concepts using interactive animations. Another type of simulation deals with the development of a virtual laboratory in which the student can conduct laboratory tests and interpret the results as if they were in a real laboratory. Both of these types of simulations can be delivered on the Web or on portable storage media such as CD. The simulations are integrated into an interactive multimedia courseware that contains interactive problem solving, electronic quizzes, a glossary, notation, a notepad, and computer program utilities in addition to the virtual laboratory and interactive animations of the selected topics. The simulations were developed using various royalty-free, commercial software such as Authorware. Preliminary evaluations indicate that simulations can significantly enhance the presentation of some topics and improve learning and retention.
