Yes they can.  At this time only files up to 2mb in size can be uploaded.  If you have a bigger file to upload, contact the site adminstrator directly (BradWilson) and we will get it on the site by another method.  This can be a way for us to share how lessons are taught and even a way for us to exchange video or audio messages between classes across the province.

To upload an audio or video file, simply follow the same procedure used to upload text files.  (See :  "How do I upload text files to the site?" in the FAQ section.)
