Support and feedback loops

When something goes wrong, how fast do we hear and fix it?

Every term below is defined in the words of support and feedback loops, guide R22 of craft guides for educational technologists, and opens the guide at the slide where it is taught. 26 of the 49 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. 4 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.
