      An argument is appearing in Los Angeles over whether a newspaper should publish teachers' names

along with an analysis of how well they do in raising their students' standardized test scores.

Some people argue that transparency(透明) should exist at all costs, but others hold that it's unfair to

label individual teachers using possibly flawed(有瑕疵的) statistics. Some worry that anger over the

forthcoming Los Angeles Times article will make people oppose so-called "value added" analysis of

teacher performance, which is the method the Times uses.

      "This incident with the L.A. Times is where the advocates(提倡者) for value-added are getting a bit

ahead of themselves," says Douglas Harris, an education professor. "Teachers are already feeling

under the gun on this kind of thing."

     "Value-added data" is the latest trend in teacher responsibility: the idea that a student's gain from the

previous year's test ? as opposed to his or her overall performance ? can be measured and tied to the

latest teacher.

     "There are too many variables(变量) in the testing process," says A.J. Duffy. But he says he opposes

using value-added data in evaluations at all, although he acknowledges it could be a useful tool to give

teachers feedback. "I believe in a system that emphasizes the whole student, not just standardized tests,"

he says.

     Proponents(支持者) of value-added say that's a valid criticism, agreeing that no one should expect

that student gains on a standardized test could capture the creativity or broader enrichment that goes on

in many teachers' classrooms. The District of Columbia which attracted argument for its decision to fire

teachers based in part on value-added data, uses that data for 50 percent of the evaluation, relying on

other measures such as classroom observation for the rest. "No one is suggesting using it as a single

measure of performance," says Paige Kowalski.

     Barnett Berry, a professor, is even more critical of it. Value-added data can be useful, he and others

say, but it's important to acknowledge its limitations. It doesn't take into account, for instance, constant

student absence and learning gains due to summer school, after-school programs, or supplemental

teachers, such as reading specialists.
