with you all.&nbsp; It&#8217;s a paper that is critical of value-added models
for evaluating teachers.&nbsp; The value-added approach came up in a discussion
following Brent Duckor&#8217;s talk at the Rasch SIG meeting last week.&nbsp;
In that discussion, I described papers such as the one in this link.&nbsp; It
was my opinion that value added models are bad statistics, as opposed to the
good measurement work described by Brent.&nbsp;&nbsp; &#8220;Good&#8221;
statistical practice includes, among other things, recognizing the limitations
of one&#8217;s statistics. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<o:p></o:p></span></font></p>
