A Few Random Thoughts about the Time article.

Maybe you've read it.

A few things jump out at me. Here's a big one:
One research team relied on a "a controversial tool called value-added measures (VAM)" to measure teacher effectiveness, and they "found that replacing a poorly performing teacher with an excellent one could increase students' lifetime earnings by $250,000 per classroom."
That's a pretty big number alright, almost big enough to make you lose sight of the details ... if you're a low grade moron or someone with a axe to grind who doesn't mind being disingenuous.

Lifetime earnings of $250,000 per classroom works out to $10,000 lifetime earnings difference per kid.  Assuming the average person works for about 40 years, that works out to a difference of $250 extra dollars per year, a whopping extra 12.5 cents per hour ... and that's if you replace a poor teacher with an excellent one for all twelve years of schooling.

This is what is known in mathematical and statistical circles as an "insignificant" increase for which we have to use a tool that the Vermont Commissioner of Education (and pretty much everyone else) has said is a "broken measurement system" that "does not work". She went on to say that it would never be used in Vermont because of it's ineffectiveness. "It would be unfair to our students to automatically fire their educators based on technically inadequate tools."

And where, besides a hole in the ground, did that number get pulled from?

Let's not ignore the dubious premise that thousands of "excellent" teachers are just waiting to be hired ... ready and eager to take the place of the losers.

Funny thing is, we're doing pretty well despite the fact that we have been forced to label every single school in the state as "low performing": 
 In 2013, the federal Education Department released a study comparing the performance of US states to the 47 countries that participated in the most recent Trends in International Mathematics and Science Study, one of the two large international comparative assessments. Vermont ranked 7th in the world in eighth-grade mathematics and 4th in science. Only Massachusetts, which has a comparable child poverty rate, did better.
So Time magazine interviewed a couple of billionaires about their opinions of public education and teacher tenure. "Shocking!" they said. "You can't fire a bad teacher."

Really?  Have they ever tried? The usual reason that principals can't fire a "bad" teacher is because the principal has no way of knowing which teachers are "bad" teachers - the new evaluation procedures are long on typing every word but very short on actually listening to the teacher teaching the class. If you are focused on typing every word said, then you aren't paying attention and you aren't "taking notes" - the inability to multitask is something I warn my students of constantly. Incidentally, and ironically, so does the principal.

The other reason that most "bad" teachers can't be fired? They're not "bad" teachers. Most of the time a teacher who is labeled "bad" is someone who has spoken up at a faculty meeting, stood up for themselves or others, worked against the desires of the principal.

The truly bad teachers are the ones who don't get noticed because they never improve, who hand out the same worksheets year after year, who don't say anything controversial, who allow students to wallow and get mired in an academic mudpit ... but who somehow get As so their parents don't say anything, who have a degree from a prestigious university but who are universally reviled by their students as lousy teachers, who dutifully fill out the silly paperwork and follow every administrative whim with fervor, never considering the best interests of the students, doing just enough to placate but never enough to teach.

Here's how to get yourself fired in public schools WITHOUT tenure:
  • Be gay/lesbian, or any other LGBTQ. (Seen it.)
  • Be Experienced in a cost-cutting era. (Big pressure)
  • Be Muslim, or Black or Latino or other "minority" who is "uppity" or in some other way "doesn't behave" (actually has an opinion and isn't afraid to say something).
  • Get pregnant. (True story)
  • Speak up for the Rights of the students/ disagree with admin is any way.
  • Actually do something bad or criminal.
Except for the last one of course, that will never be the reason on the form letter. That would be discrimination. Rather, you'll find vague job performance metrics and "documented tardiness issues". You'll find overwhelming but never specified "evidence" of misconduct. You'll find everything but the actual discrimination.

Here are some ways you can get fired from a school WITH tenure:
  • Do something bad or criminal.
  • Be a bad teacher.
