Abstract

This paper illustrates the use of multimedia, digital still images and PowerPoint slide shows (other presentation applications may be used), to guide the student through one of the most common tasks in the clay mineralogy laboratory, extracting the less-than-two micrometer fraction. A second activity to be demonstrated employs a digital video clip to enhance instruction in the smear-slide technique for the preparation of oriented aggregates for XRD analysis. Each provides a stand-alone introduction to basic laboratory methods and equipment that frees the instructor to devote more time to more challenging topics. Both PowerPoint presentations are available on the senior author's website and The Clay Minerals Society website and may be freely downloaded for non-commercial use.

The increased availability of the personal computer in the last decade has made it possible for educators to provide desktop access for every student to a multitude of applications. They generally result in an improved presentation of subject matter and procedures to enhance the learning process. In this environment, “multimedia” has taken on a special connotation to imply that the latest computer-based audio and visual technologies are being employed. It has become one of the terms associated with progress in education today. However, multimedia simply means more than one method of communication. Computer-based multimedia should not replace individual instruction and should only be used when they clearly enhance instruction. These new approaches are particularly suitable for repetitive tasks such as those associated with laboratory procedures. A good introduction to the general use of multimedia in education
