Wells was a place where women did not have to fuss over their appearance or fight to be taken seriously by their professors. They could enjoy the camaraderie of their campus sisters and their playful traditions. Besides jumping into the lake, the women dance around the maypole each May and kiss the feet of the statue of Minerva, the Roman goddess of wisdom, before exams.

Ms. Alexander said,“People told us we wouldn’t notice a difference, but from the moment men arrived on campus not could notice a difference. Waking up early to put on makeup, and that’s odd,” she said.

Henry Wells, a founder of Wells Fargo and a friend of Cornell’s benefactor, Ezra Cornell established this college, when women were not considered capable of higher learning. “Give her the opportunity,” he wrote.

Henry Wells, a founder of Wells Fargo and a friend of Cornell’s benefactor, Ezra Cornell established this college, when were not considered capable of higher learning. “Give her the opportunity,” he wrote.

The great-great-great-great granddaughter of Henry Wells, Stephanie Redmond, 18,of Washington State, said that earlier this year a Wells student had tracked her down and asked her to support the protest. But Ms. Redmond said the move the move to admit men had encouraged her to enroll at Wells this year as a freshman. She plans on a career in engineering, a male-dominated field, and said attending an all-women’s college might have put her at a disadvantage.

D. The founder hoped to give women opportunities of higher education.

But what is teacher quality? How can one measure it reliably?

An analysis is issued a sample of data a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students’ gains on standardized tests: Mr. Smith is presumably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do.

Though this approach is appealing, there are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high there is little room for improvement?

The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable teacher characteristics.

The first finding is that is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students’ achievement than others.

Second, easily observable characteristics like having a master’s degree or a passing score on the teacher certification exam are not correlated with teacher effectiveness.

Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, most teachers hit their stride.

It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early).

From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time.

The authors also investigate the contentious issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better of their own race )or an empathy effect (teachers empathize better with students of their own race )or something else entirely.

The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model.
