* Students today are growing up exposed to a “flood” of information from the Internet, television, newspapers, magazines, podcasts, and many other mass media. These inevitably include biased or distorted information from questionable or unreliable sources. Therefore, they must learn to distinguish reliable/unreliable information in order to protect themselves from being misguided or manipulated. * So what is the Opposing Viewpoints Resource Center? It is a collection of various materials on controversial contemporary topics such as “animal experimentation”, “gun control”, “stem cell research”, “ecology” an so forth. The core of the database is its collection of 8700 “Viewpoint” essays, which are opinionated essays or articles taken from Greenhaven Press’s print Opposing Viewpoints anthologies and other related publications. The viewpoints represent both sides of the argument, pro and con, including various shades in between. There are also 4700 reference articles explaining each topic from a more neutral standpoint and providing basic knowledge and background of the topic, taken from Gale’s various encyclopedias and reference works. We also include articles from 140 periodicals and newspapers, including the NYT, which provide the latest coverage on these topics, and which are updated daily. There is also a wealth of primary source material, such as Gallup polls on public opinion, excerpts from legislation or commission/committee reports, NGO publications, judicial cases, and other “raw” material that students may contemplate. Finally, it includes many multimedia materials, including hundreds of photographs, links to websites, and thousands of links NPR podcasts with full transcriptions. * Take a look at the main subjects covered in OVRC.
