Newspapers and news organizations are one of the early adapters to RSS technology. On a regular basis I'll be updating an OPML with a list of newspapers that provide Education feeds and maintaining it here.
The BBC and New York Times are the veterans of this group. I'm not sure how long the Christian Science Monitor has offered their Learning feed. More recent are the Philly papers and now the Washington Post.
Please let me know if you know of additional feeds.
