For educators designing lesson plans on journalism, the Reporters Without Borders site can offer insights into the lives of journalists working around the world. Readers may browse the site according to region, including information on Africa, Americas, Asia, Europe/Ex-USSR, and Middle East/North Africa. Selecting any of these tabs triggers a drop down menu of respective countries. Selecting any of the countries navigates to an archive of all the articles published about that country written in the past decade or so. Other important features of the site include a World Press Freedom Index, which evaluates each nation on a number of variables to assign them a yearly ranking. In the 2015 rankings,for instance, Finland was found to be the most powerful proponent of a free press in the world, while the United States was ranked number 49, after South Africa, Samoa, El Salvador, and many other nations.
