*******ANNOUNCEMENT***********ANNOUNCEMENT***********ANNOUNCEMENT***** DIMACS (Center for Discrete Mathematics and Computer Science) is pleased to announce the availability of the DIMACS Educational Module Series. ********************************************************************** The first two modules in this series are available on line at: http://dimacs.rutgers.edu/Publications/Modules/moduleslist.html The purpose of the DIMACS Educational Module Series is to make available to students and teachers in modular form materials in the area of discrete mathematics and computer science. We are especially seeking materials that "grab" ones intellectual attention, show relationships between ideas that one might not realize are related, or are just plain nifty. If the materials suggest or have already been used in applications outside of mathematics so much the better. We are also interested in novel and non-standard ways of looking at traditional topics. We are especially interested in materials that have not been exposited previously at the undergraduate or high school level. We are not ordinarily looking for standard treatments of standard topics even if these topics are not available in module form. Further information may be obtained from the series editor, Joseph Malkevitch, York College (CUNY). He can be reached at: joeyc at cunyvm.cuny.edu or from the link at: http://dimacs.rutgers.edu/Publications/Modules/generalinfo.html where you can also find general information about the modules. We hope that you and your students enjoy using these materials and we would welcome suggestions for topics you would like to see modules treat as well as titles for manuscripts for the series that you might like to submit. We also welcome feedback about your experiences in using the modules.
