"If a measurement matters at all, it is because it must have some conceivable effect on decisions and behaviour. If we can't identify a decision that could be affected by a proposed measurement and how it could change those decisions, then the measurement simply has no value”
- Douglas W. Hubbard
Do we do this enough in education? Honestly and rigorously identify the decisions that could be affected by a proposed measurement.
And if we do - do we ever reconsider the measuring?
Because we should.
