In any event, measurement of HCS (hypothetical cognitive structure, i.e. IQ) is probably not an issue about which teachers should be overly concerned. While there are special instances when labelling a student might be advantageous, for the most part it is not. Teachers are generally more interested in what is changed by instruction, not in what is relatively untouched by it. – Biggs & Collis, 1982.
