Does it matter where public-school teachers send their own children to school? If so, how and why? What can we learn from them?

What we are grappling with here is the question of connoisseurship. Stock analysts, for example, watch carefully when corporate directors buy or sell the stock of companies on whose boards they serve.

Similarly, we can assume that no one knows the condition and quality of public schools better than teachers who work in them every day. If these teachers are more likely than the general public (which may not have nearly as much information or expertise in these matters) to send their own daughters and sons to the public schools in which they teach, it is a strong vote of confidence in those schools. If they do not, then we might reasonably conclude that those in the best position to know are signaling a strong "sell" about public education in their communities.
