We have had our fill of books about what’s wrong with our schools, most written by non-educators with an ax to grind.

Fortunately there is a new genre of books now appearing, mostly from publishers willing to take a chance with a new author. This new genre consists of books written by experienced teachers, who tell about real life in real schools and offer insights into realistic ways to improve schools.

Ken Previti has written an admiring review of David Greene’s new book, “Doing the Right Thing: A Teacher Speaks.”

If you want to know what schools need, ask a teacher, not a newspaper pundit or a financier. As Previti puts it, “Teachers should teach. Eye doctors should examine and prescribe what is needed for better eyesight.

But in this benighted time, decisions are made by legislators, politicians, and bureaucrats. Mandates rain down on schools. Wise teachers like David Greene will help us find our way back to a better path.
