<p>I think I know what kayf is talking about.</p>
<p>Before all professions were open to women, top female students very often chose teaching as a career because it was the most intellectually challenging career open to them.</p>
<p>Now that women have many other choices, very few of the best and the brightest female students choose to become teachers. So teachers tend to come from somewhat lower academic ranks. Some people feel that this has led to a decrease in the quality of teaching – although I’m not sure whether that is true. How well a person teaches may not necessarily be directly related to that person’s academic ability.</p>
