Letter to the editor: Stamina required

Notes: "In the November [2012] issue, I noticed an error in the article on what teachers earn ["Report on education', p. E3]. The total average hours of formal classroom teaching per year was indicated as 7,391 hours. Since the average comes out to more than 20 hours a day seven days a week, I would love to meet the children with the stamina to endure such a program and the teacher who could present it. I would guess the average is closer to 739 hours, since the average teacher works about 180 days a year with less than five hours a day of instruction per child". [Text of entire article.]
