Question

How to measure the performance or goodness of communication about an open assessment?

Answer

$GC = \frac{Av*Re*Ac*Us}{Ef}$

Explanations:

• P(A) = probability of A, N(A) = number of people in A
• Calibration, Informativeness, and Coherence: These are not relevant for the assessment of communication methods and are therefore not used.
• Availability (Av): number of people (users) hearing the content N(content received)
• Relevance (Re): P(content is relevant for the user|content received)
• Acceptability (Ac): P(content and production are acceptable in user's context|content is relevant)
• Usability (Us): utility of content (in onors) to a user finding it acceptable: U(content|content acceptable)
• Efficiency (Ef): Sum of costs (in working hours): Sum(talking, reading, using content)
• Goodness of communication (GC): overall outcome divided by resources used. Note resources only include communication costs, not those to produce the information.

Rationale

Open assessment framework. The roles of different participants lead to different kinds of communication and information work.

Drafts of estimates for calculations. The idea is to test whether a quantitative approach makes sense, i.e. whether it is possible to give plausible answers as parameters in the calculation.
