(To generate the weights, we regressed a teacher's average student - achievement gain in one class against the three different measures from another class, resulting in weights of.758,.200, and.042 on value - added, student survey, and classroom observation, respectively).
We excluded kindergarten and first - grade teachers because earlier achievement exams were not available for their students; this prevented us from developing a «value - added» measure of student learning.
The May 23 conference at the Urban Institute, a think tank based here in the nation's capital, examined the policy implications for value - added statistical designs, which typically measure students» learning gains from one year to the next.
States and districts should have been focusing on the real end goal — differentiating the best teachers from those who are merely satisfactory and those who continue to struggle — a task that would not have required complicated mathematical formulas designed to measure each teacher's «value - added» to student achievement.
We measured value - added with the average change in combined reading and math scores for a school's students between the end of 3rd grade and the end of 4th grade; we measured cross-cohort changes with the change in 4th grade scores from one year to the next.
Improvements can be measured in two basic ways: the improvement in performance for a given group of students from one year to the next (known as a value - added approach), or the improvement in performance across different groups of students (which we will refer to as cross-cohort changes).
From teacher evaluation systems to value - added modeling to the recent Vergara decision in California, reformers have increasingly focused on selecting, measuring, developing, evaluating, and firing teachers as the key to educational improvement.
Misunderstanding the Gates Foundation's Measures of Effective Teaching Project Education Next, January 10, 2013 «MET argues for a more balanced set of weights among value added, classroom observations, and feedback from student surveys on other grounds.
The value - added measures are designed to provide estimates of the independent effect of the teacher on the growth in a student's learning and to separate this from other influences on achievement such as families, peers, and neighborhoods.
These and other findings with respect to the correlates of teacher effectiveness are obtained from estimations using value - added models that control for student characteristics as well as school and (where appropriate teacher) fixed effects in order to measure teacher effectiveness in reading and math for Florida students in fourth through eighth grades for eight school years, 2001 - 2002 through 2008 - 2009.
They claim that value - added studies that measure gains from one point in time to the next fail to account for the fact that «two students can have pretest scores and similar schooling conditions during a grade and still emerge with different posttest scores influenced by different earlier schooling conditions.»
From among the array of growth measures, I recommend true value - added models or student growth percentiles (though I prefer value - added models for reasons described here).
The question should instead be, «If scales from a testing regime are used within a value - added process, is there evidence that measures of student progress are influenced by the distribution of student achievement levels in schools or classrooms because of a lack of equal - interval scales?»
Nonetheless, we all want our kids to have at least a few excellent teachers along the way, so it's tempting to buy into hype about value - added measures (VAM) as a way to separate the excellent from the horrifying, or least the better from the worse.
It is based on a comparison of two different value - added scores for teachers: one derived from the regular state assessment (which varies by participating district) and the other from an alternative assessment that is specifically designed to measure students» depth of higher - order conceptual understanding in each subject.
Join Teach Plus on Thursday, November 17, from 5 - 7:30 pm for an important conversation on the questions surrounding student growth measures with experts Noah Bookman, LAUSD Program and Policy Development Advisor, Dr. Rob Meyer, research professor and Director of the Value - Added Research Center at the University of Wisconsin, and Chris Bertelli, Executive Director at The College - Ready Promise.
This approach is different from using value - added measures of standardized tests as a significant component in an evaluation and separates the San Jose system from one favored by reform groups like StudentsFirst.
I've already seen at least one post from a teacher of «gifted» students, complaining that she now has a negative value added measure because her students started the year with very high test scores.
The most controversial of them include what is known as value - added models1 that use data from standardized tests of students as part of the overall measure of the effect that a teacher has on student achievement.
Two academic researchers from the University of Southern California and the University of Pennsylvania looked at these value - added measures in six districts around the nation and found that there was weak to zero relationship between these new numbers and the content or quality of the teacher's instruction.
But as with any system of ranking or scoring, value - added measures are far from perfect; they are subject to bias, distortion and error.
[14] These results do not mean that value - added measures can't be used productively as incentives; evidence from Kenya and India, at least, suggest that they can.
[22] To put this in perspective, one study finds that only 28 to 50 percent of teachers who were ranked in the top fifth on value - added measures one year were still ranked in the top fifth in the subsequent year, and 4 to 15 percent of teachers switched from the top fifth to the bottom fifth.
One major vendor of value - added measures (i.e., SAS as in SAS - EVAAS) long has held that the tests need only to have 1) sufficient «stretch» in the scales «to ensure that progress could be measured for low - and high achieving students», 2) that «the test is highly related to the academic standards,» and 3) «the scales are sufficiently reliable from one year to the next» (see, for example, here).
Other differences come from the tests on which the value - added measures are based; because test scores are not perfectly accurate measures of student knowledge, it follows that they are not perfectly accurate gauges of teacher performance.
Secondary grades differ from elementary grades in ways that are meaningful for the validity and reliability of value - added measures for secondary teachers.
In summary, value - added measures vary for the same teacher from year to year, subject to subject, and student group to student group.
Likewise, though, «[a] number of states... have been moving away from [said] student growth [and value - added] measures in [teacher] evaluations,» said a friend, colleague, co-editor, and occasional writer on this blog (see, for example, here and here) Kimberly Kappler Hewitt (University of North Carolina at Greensboro).
Thus, value - added measures of improvement — particularly those based only on data from the beginning and end of a single year — will be very imprecise.
We can think of value - added estimates as measuring three components: (1) true teaching effectiveness that persists across years; (2) true effectiveness that varies from year to year; and (3) measurement error.
Accordingly, and also per the research, this is not getting much better in that, as per the authors of this article as well as many other scholars, (1) «the variance in value - added scores that can be attributed to teacher performance rarely exceeds 10 percent; (2) in many ways «gross» measurement errors that in many ways come, first, from the tests being used to calculate value - added; (3) the restricted ranges in teacher effectiveness scores also given these test scores and their limited stretch, and depth, and instructional insensitivity — this was also at the heart of a recent post whereas in what demonstrated that «the entire range from the 15th percentile of effectiveness to the 85th percentile of [teacher] effectiveness [using the EVAAS] cover [ed] approximately 3.5 raw score points [given the tests used to measure value - added];» (4) context or student, family, school, and community background effects that simply can not be controlled for, or factored out; (5) especially at the classroom / teacher level when students are not randomly assigned to classrooms (and teachers assigned to teach those classrooms)... although this will likely never happen for the sake of improving the sophistication and rigor of the value - added model over students» «best interests.»
It is important to note, however, that even if the conclusions from these studies are right, they provide evidence about whether value - added measures are valid on the average across large numbers of teachers.
The largest study of performance incentives based on value - added measures comes from a Nashville, Tennessee study that randomly assigned middle - school math teachers (who volunteered for the study) to be eligible for performance - based pay or not.
[4] The adequacy of the adjustments across schools in value - added measures, which would allow the comparison of teachers in different schools, is less clear because schools can contribute to student learning in ways apart from the contribution of individual teachers and because students sort into schools in ways that value - added measures may not adjust for well.
The well - known Measures of Effective Teaching (MET) project funded by the Gates Foundation reports results from experiments that also address the validity of value - added at the middle and high school levels.
The null results from most studies contrast with some recent evidence suggesting that programs that combine value - added with other measures of performance, or which use only other measures, can lead to improvement.
In particular, there is growing agreement that random error is the biggest problem — this is mostly what makes value - added measures bounce around so much from year to year.
It is clear from the research so far that value - added measures will never be completely stable across time, topics, or student groups, nor would we necessarily want them to be because true teacher effectiveness likely varies across these dimensions.
This means that, even setting aside other issues with the measures, current standard value - added measures for teachers who concentrate their work in particular tracks in middle and high schools will suffer from validity concerns.
Many also are likely to be interested in outcomes other than those measured by value - added, such as the number of teachers, or types of teachers that graduate from different institutions.
