I had a very compelling unplanned lesson in accessibility today. In a Zoom session, we were asked to watch a video. Rather than play the video via Zoom, which has problems, links to the video on three platforms were provided. But I could not get any to work. Normally I would read the notes, or the transcript, but could find neither, so I had no idea what it was about. I then took part in a discussion of the video and spent about ten minutes feeling excluded and a but of a fool, as I had no idea what they were talking about. As I can normally see and hear, this is not a common problem, but for those who can't, it is. I need to remember to include alternate formats in my own teaching, especially as I helped make this Australian law.
