Bad teaching is a common explanation given for the disastrously inadequate public education received by America’s most vulnerable populations. This is a myth. Aside from a few lemons who were notable for their rarity, the majority of teachers I worked with for nine years in New York City’s public school system were dedicated, talented professionals.Before joining the system I was mystified by the schools’ abysmal results.I too assumed there must be something wrong with the teaching. This could not have been farther from the truth.
Teaching French and Italian in NYC high schools I finally figured out why this was, although it took some time, because the real reason was so antithetical to the prevailing mindset. I worked at three very different high schools over the years, spanning a fairly representative sample. That was a while ago now, but the system has not improved since, as the fundamental problem has not been acknowledged, let alone addressed. It would not be hard, or expensive, to fix.
