Fiona Beal ran an online blogging course for teachers in South Africa and realized what a great teaching tool blogs can be. She shares some free Web 2.0 applications that can be used in technology integrated classrooms and linked to in blogs, including Box.net to link documents, Embedit.in to embed documents, Slideshare.com to present slideshows, Screencast-o-matic for screencasts, and Vocaroo.com for audio recordings. These applications allow teachers to add rich content and instructions to their blogs.
