How good am I at explaining?

As teachers, our audience, our students can be a great source of feedback upon our craft. They see you teach more than you do. So one way to develop our ability to explain things well is not only in their understanding of the subject, but also in identifying what aspect(s) we need to improve upon. This may be a structural, signalling, clarity or supportive feature of your communication. Further details can be read here and here and here.

These features are broken down in the following student voice survey. As always I worry that a checklist in the wrong hands turns into a management tool, and that is not the intention here. So if anyone tries tell them to do one. This is a professional reflection tool, for teachers to check their own classroom practice on their own or with some feedback from their classes.
