In a Government or Civics class, students could use an aggregator such as Google Alerts to follow a news story and get the point of view of multiple online news sources, rather than only looking in the archives of one. A teacher could develop a class around the issues of bias in journalism. I am currently using it to follow stories on crime in museums for an exhibition I am putting together.
