A blog is a website which usually takes the form of a series of posts arranged in reverse-chronologocal order, i.e. the most recent post appears at the top of the page. Students writing their own blogs, commenting on other people’s blogs, and consulting blogs written by experts in their field are common learning activities in Higher Education today.
A wiki is a website where users can easily add, edit and delete content without specialist software or technical knowledge. Users can create new wiki pages and link them to others, and they can edit existing pages, including those created by other learners.
