"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”
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.
