Teeter-Totters Have Two Ends
Popham, W. James
Measurement: Interdisciplinary Research and Perspectives, v11 n4 p189-191 2013
The author recalls that as a child, he grooved on teeter-totters. Also known as a seesaw, a teeter-totter is a long, narrow board that's elevated with a pivot point in the middle so that as one end goes down the other end goes up. When going up or going down, sometimes quite rapidly, teeter-totters can provide their two riders with some serious thrills. The author learned a fundamental truth early during his teeter-tottering years, namely, that it takes two people to make a teeter-totter work. It is this fundamental law of the playground that causes him concern about Adam Wyse's comprehensive analysis of construct maps and their role in standard setting. The author asserts that Wyse may be sitting on one end of a teeter-totter without the benefit of someone at the other end. Just as certainly as one can get a rush from moving up or down while a companion makes opposite moves, it is ineffectual to sit solo and unmoving at one end of a teeter-totter. The author contends in this commentary that Wyse and other members of the construct-map clan should try not to spend so much effort in after-the-fact refinement of their construct maps that they do not have time to address with equal vigor the performance-level descriptors (PLDs) that represent such a critical component of their work. In other words, the author believes that proponents of construct maps may be spending so much time in their efforts to use those maps as adjuncts to the standard-setting process that they are giving too little attention to PLDs--the supposed starting point for a standard-setting enterprise.
