RSS (Really Simple Syndication) is a system which allows the user to subscribe to multiple blogs and websites who can then automatically update the users account with new publications.
This is essentially a time saving tool as it allows the user to minimise time spent looking for new publications.
As a teacher, monitoring students blogs may become necessary in the future, so an RSS would become invaluable. Allowing a teacher to passively monitor blogs without having to actively search for new publications from students.
Students will benefit in a similar way. Enabling them to more easily provide feedback on the blogs of peers, and in turn, make it much easier for their peers to offer feedback on their own publications. This promotes a collaborative learning environment for both teachers and students.
