The ChemWiki
The ChemWiki project is a new approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written partly by students and partly by faculty members resulting in a free Chemistry textbook to supplement or supplant conventional paper-based books. Anyone can view, although a freely available account is required to edit the site modules.

Wireless Networking in the Developing World
The massive popularity of wireless networking has caused equipment costs to continually plummet, while equipment capabilities continue to increase. By applying this technology in areas that are badly in need of critical communications infrastructure, more people can be brought online than ever before, in less time, for very little cost. We hope to not only convince you that this is possible, but also show how we have made such networks work, and to give you the information and tools you need to

Internet Ancient History Sourcebook
The Internet Ancient History Sourcebook is a companion to the Internet Medieval Sourcebook and the Internet Modern History Sourcebook. The Medieval Sourcebook is both a classroom resource and the largest collection of online medieval texts. The Ancient and Modern Sourcebooks have a different role: since there are already ample online repositories of texts for these periods, the goal here is to provide and organize texts for use in classroom situations. Links to the larger online collections are

Cross Layer Identity Management
This video addresses the problem of today's Internet users who have to pass several authentication and authorization procedures in the usage of Internet services, due to the fact that services consumed require involvement of different service providers. Such a situation exists in a Virtual Organization environment. This video presents the state of the art in federated identity management, the need for cross layer identity management, and approaches followed within the Akogrimo project. This incl

Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from

Using the Internet to Promote Inquiry-Based Learning
This site is an e-paper that describes a structured approach to inquiry-based learning using the World Wide Web as a primary information resource. Specifically, the paper addresses an 8-step process that begins with an essential question and ends with a product produced by students, typically completed in a cooperative setting. The paper also discusses the skills required by both student and teacher to make inquiry-based learning with the internet a successful endeavor. Finally, the paper discus

Field Project Tutorials: A Virtual (Structural) Field Project
This virtual five-day field mapping project allows students to construct a geological map from data provided by the web site. Students collect geologic, structural, paleontologic, strain and microstructural data observed at specific localities. Students are then able to derive a structural history for the area, including a field map, stereographs, and deformation plots. The site contains photographs and images, data, and all information that is needed to complete the exercise. It also provides s

Movie in the Making
In this project students will report on a book by describing how they would turn that book into a motion picture. After reading and studying the main components of their novel (character, plot, conflict, climax and denouement), students will use their imaginations to explain how they would cast and direct the movie versions. This project also provides enrichment activities where in the students will access archived materials such as the Academy Awards Data Base, movie posters, and movie reviews.

Allies and Aliens
In the learning module Allies and Aliens students assume the role of agents from planet Earth who must assess varying degrees of prejudice and misinformation as they visit Web sites from other planets. Because most kids don't think to look for bias or false information online and subtle forms of racism may be difficult to recognize, Allies and Aliens uses the pretense of an evaluation mission to keep players from guessing its true purpose right away. The mission is divided into two parts. On Day

Stereotypes of the French
This unit comprises four major lessons which are distinct yet cumulative. In the first lesson, the students will lay the groundwork for their examination of French stereotypes by generating those stereotypes themselves. They may draw, write, or find examples of what they think are "typical" French things. In the second lesson, they will be required to change perspective -- instead of being the examiners, they will be the examined culture. Students will look at various examples of stereotypes of
