Also, there is a logic to using tests to devise a solution, because test scores do
predict later - life outcomes such as college - going and earnings; and important recent evidence from Stanford researcher Raj Chetty and colleagues shows that having a «high
value - added»
teacher — one who improves student test scores — also positively
predicts these outcomes.
Student surveys: Many
teacher evaluation systems already incorporate the results of student surveys, which research suggests can also
predict school and principal
value - added.
Important work by Stanford University researcher Raj Chetty and his colleagues finds that
value - added measures of
teacher quality
predict students» outcomes long into the future.
In addition, research showing that
value - added measures outperform other
teacher characteristics at
predicting a
teacher's impact on student growth in future years — and that they also capture information on
teachers» impacts on longer - term life outcomes like teen pregnancy, college going, and adult earnings — served as an important justification for differentiating
teacher effectiveness.
This statistical methodology introduced a new paradigm for
predicting student academic progress and comparing the prediction to the contribution of individual
teachers (or
value added) as measured by student gain scores.
This impact on average test scores is commensurate in magnitude with what we would have
predicted given the increase in average
teacher value added for the students in that grade.
When we account for such factors, we find that
teachers»
value - added is not related to prior achievement, but continues to
predict end of year achievement.
Americans still do not recognize that once there are only effective
teachers the
value added analysis will allow school administrators to
predict all of the students that can not be educated with effective
teachers.
Because
value - added measures were so reliable at
predicting teachers» performance, the researchers urged school districts to use it as a «benchmark» for studying the effect of other measures.
Because
value - added measures were so reliable at
predicting teachers» future performance, the researchers urged school districts to use it as a «benchmark» for studying the effect of other measures.
Teacher performance was calculated by using a
value - added model, which
predicts how students will do in a given year based on how they performed in the previous year.
Many states are using «
value - added» models to grade
teachers, which involve complex formulas that take into account factors like a student's past test scores and attendance to
predict what his or her score will be on this year's test.
A
teacher's observation scores are supplemented by a so - called «
value - added» rating, which is calculated by determining whether a
teacher's students made greater gains on standardized tests than statistical models would have
predicted.
If the formula
predicts teacher A's students will get a 2.7 and they get a 3.0, then that
teacher gets a +.3 as his «
value - added» score.
If the student exceeds the
predicted score, the
teacher is credited with «adding
value.»
«
Value - Added» is, once again, how much better or worse a
teacher's students do on a standardized test compared to what a complicated formula
predicted the students would get.
At the same time, they incorporate classroom evidence of student learning and they have recently been shown in larger - scale studies to
predict teachers»
value - added effectiveness, so they help ground evaluation in student learning in more stable ways.
Districts could also track, over time, the average achievement of grade - level cohorts within schools to determine if performance changes as
predicted by the
value added by
teachers who transfer into or out of schools and grades.
Consequently, the loss of a
teacher with high
value - added would not affect average achievement, since removing that
teacher would have no change on the cohorts, and since cohort - to - cohort changes in achievement would be smaller than that
predicted by
value - added.
The
value - added formulas actually compare how students are
predicted to perform on the state ELA and math tests, based on their prior year's performance, with their actual performance, as
Teachers College Professor Aaron Pallas wrote here.
However, two careful, large - scale studies, reviewed in detail below, suggest that despite the lack of persistence of
value - added on future test scores, one year of experience with a high -
value - added
teacher predicts higher rates of college attendance and adult earnings, as well as other important outcomes.
We see a statistically significant but much smaller impact on earnings (having a
teacher with one standard deviation higher
value - added
predicted earning $ 350 per year more than expected at age 28).
Teachers whose students do better than
predicted are said to have «added
value»; those whose students do worse than
predicted are «subtracting
value.»
Two recent studies provide evidence that attending the class of a high -
value - added
teacher predicts higher - than - expected educational attainment, earnings, and other adult outcomes.
Today, the district uses Star 360 for progress monitoring,
predicting student proficiency on standardized tests, and as a data element in
value - added modeling processes for
teacher evaluation.
Using a statistical technique called
value - added modeling, the
Teacher Data Reports compare how students are
predicted to perform on the state ELA and math tests, based on their prior year's performance, with their actual performance.
Consider, for example, the study that shows that cohort - to - cohort changes in achievement are
predicted by the
value - added of
teachers who leave a school or grade.
Some educators and critics question the ability of
value - added modeling to accurately
predict teacher performance.
Additional analysis of the ability of
value - added modeling to
predict significant differences in
teacher performance finds that this data doesn't effectively differentiate among
teachers.
A Chicago based company, TeacherMatch, claims to use algorithms to
predict the effect that a
teacher candidate will have on
value added student test scores.
