Because teachers do not seem to feel that their measurement skills
are inadequate, it is tempting to characterize any problems caused by
limited undergraduate training as self-correcting. That is, through
their experiences in the classroom, teachers eventually acquire measurement
skills on their own. Unfortunately, the idea that the problem
corrects itself is unsupported by empirical research, which has
indicated that there are widespread deficits in the measurement skills
evidenced by practicing teachers (Carter, 1984; Fleming & Chambers,
1983; Newman & Stallings, 1982; Stiggins and Bridgeford, 1985).
