Firstly, re-watching my first teaching video of the year was slightly uncomfortable. I also feel a little anxious when watching a video of myself teaching (or even just talking, really) so I was concerned to see the first video again.
I noticed right away that I appear to be significantly less comfortable, both with teaching and with being filmed. I can see in the footage that I am aware of the camera, occasionally glancing over or completely avoiding turning towards that area. I remember that during fall quarter it took me several weeks of observations to become more comfortable with the video aspect of observations.
In terms of teaching, I also appear significantly less comfortable when considering more recent teaching footage. I stumble over my words more and seem to forget where I am going with the lesson. In general, I seem to be exerting significantly more effort to teach the lesson in this video than I might in a current video of the same lesson.
