What is CLAS?

CLAS is a media player used to record, share, and comment on videos. Videos uploaded to CLAS are stored on a secure server at UBC and you are able to control who has access to which video. CLAS is also mobile compatible, so you can record videos and make comments directly from your mobile devices. See the screen capture below outlining the main features of CLAS.   CLAS

What are the uses of CLAS?

CLAS can be used as a self-reflection tool for Teacher Candidates in the  practicum program. Teacher Candidates can record their practicum sessions, upload the videos to CLAS, review the videos and add comments to various times in the video, and even chose to share the video with their Faculty Advisors for additional comments. CLAS has also been used to facilitate discussions on lecture videos. Students have access to lecture videos, then choose to comment on the video either privately (comments only visible to the student), or publicly (comments visible to everyone in the class). Note Detailed user documentation is available at
