The author extends her appreciation to the graduate students at Mon- mouth University in West Long Branch, New Jersey. I acknowledge their assistance in researching and reviewing Earth Science Web sites, their support and enthusiastic interest in this manual and in the larger process of infusing technology into their instruction and into their everyday lives. A number of students reviewed the first chapter for relevance and usabil- ity. In addition three graduate assistants formalized the review process and provided a number of the Web sites that the author reviewed for addition in the manual. Specifically I wish to thank the following graduate stu- dents of Monmouth University: Cynthia Coughlin,.
