RSS stands for Rich Site Summary or often Really Simple Syndication. An RSS feed can be used to provide news headline links, blog postings, and much more and are especially useful if you wanted your students to be up-to-date with news or events that are relevant to your course. To show RSS feeds within your Moodle course, you need to add an RSS block and configure it to show a news feed that has already been saved.
Locating the source of the RSS feed:
Open the webpage of the site you wish to link to the your moodle page. For example, The New York Times.
Search the page for a link to the RSS feed, recognized by the following orange icon: Alternatively, search for "RSS feed" on the search engine provided by the webpage, and follow till you see the page you want, marked by the orange RSS icon.
Right click on the icon to obtain the URL for the RSS feed (alternatively copy the URL address from the browser) and copy this link to your clipboard. Make sure you double check to see that the link is not invalid and leads you to the right page (the link should end in '.xml').
