Abstract of Special Issue 27, a CD-ROM for Mac OS and Windows David M. Whisnant Department of Chemistry, Wofford College, Spartanburg, SC 29303;
[email protected] General Chemistry Multimedia Problems ask students questions about experiments they see. A computer presents high-quality videos of experiments, after which students respond to a question or request additional video to expand their experimental information. Video used is from JCE Software’s Chemistry Comes Alive! series (1). The questions ask students to apply concepts from several different parts of an introductory course, encouraging students to decompartmentalize the material. General Chemistry Multimedia Problems are available on a CD-ROM for Mac OS and Windows in HTML format and can be viewed with a Web browser. General Chemistry Multimedia Problems can be used in a variety of ways. They are designed to supplement traditional textbook problems and can be assigned as homework. They can be used as the basis for out-of-class collaborative group work or for written essays in which individual students answer the questions in detail. If classroom computer projectors are available, they can be used for in-class collaborative work or as questions on examinations. Answers to the problems are provided but are not directly available from within the problems. There are 32 General Chemistry Multimedia Problems. Each consists of four to twelve questions that have been chosen to include many of the concepts covered in a typical twosemester general chemistry course for science majors. Nineteen of the problems are based on concepts often encountered in the first semester of this course; thirteen of the problems are based on both first and second semester topics. Contents Problem titles are listed in Table 1 along with a list of the concepts needed to answer the questions and the semester in which most of the concepts needed for the question are covered in a typical introductory college course.

Curriculum Project for support during two summers at the University of Wisconsin–Madison where the original versions of these problems were developed and Charles Kay for his explanation of the Phlogiston theory. The Disorder problem was inspired by a film made by Henry A. Bent. Ordering, Price, More Information Hardware and software requirements for General Chemistry Multimedia Problems are found in the table below. An order form is inserted in this issue that provides prices and other ordering information.
