Communicating change to schools

Does the right person know what changed, why, and what to do?

Every term below is defined in the words of communicating change to schools, guide R20 of craft guides for educational technologists, and opens the guide at the slide where it is taught. 24 of the 45 are the field’s vocabulary rather than the guide’s own: words a reader will meet around this subject, defined here because the guide assumes them. 2 terms are also defined by another guide in the series; where the two differ, both wordings are given. The whole craft glossary holds all of them together.
