Email discussion with Gary Rubenstein about his analogy of students and their parents being lamps, and schools/teachers being bulbs

Here's the first, in which I respond to his analogy of students and their parents being lamps, and schools/teachers being bulbs.  Here's an excerpt from what I wrote and the full text is below:

 

Excerpt from his email: It's like when a lamp isn't working so you replace the bulb and the lamp still doesn't work.  It means that the lamp is the problem.  This isn't to say that it is impossible to increase the standardized test scores of those kids.  It just means that with limited resources it is nearly impossible.

 

My reply: I've been thinking about your lamp analogy.  If I flip the switch on a lamp and it doesn't turn on, I assume that it's a bad bulb (I.e., ineffective adults in a school) (and will be correct 99% of the time).  Put a different, better bulb in and, voila, there's light!  I'm loving this analogy!

 

But you are claiming that NO bulb will ever work -- not even a tiny flicker -- because the lamp is broken -- in other words, the kids and their parents are so incorrigible and/or beaten down by life that NO school and NO teachers can move the needle for them (at least within any realistic spending levels).  Do you seriously believe this???

 

The real problem with your lamp analogy is that you assume that the light is either on or off -- nothing in between.  Yet in your very next email, you said that even at schools with the worst test scores, there's learning going on.

 

So, if we're going to use a lamp analogy, let's talk about a lamp with issues, one in which a bad bulb will flicker very faintly and erratically, a normal bulb will produce a weak somewhat flickering light, but then there are rare and special new bulbs that manage to produce a bright, steady and long-lasting light, even when placed in the lamp with issues. The problem is that these special bulbs, while not costing any more than normal or even bad bulbs, are REALLY hard to manufacture, so they are in terribly short supply.

 

So, what should our strategy be?  Well, that's obvious, isn't it?  1) Do everything humanly possible to ramp up production of the special bulbs. Shower money on the people who've developed the new bulb technology, remove regulatory barriers, etc.  And 2) Replace the bad bulbs with the special bulbs as fast as the latter can be produced (and, in the meantime, replace the bad bulbs with at least the normal bulbs).

 

Ah, but what about the manufacturers of the bad bulbs, dominate the market currently?  They know that they produce a high number of defective bulbs, but rather than fix the problem, which would involve painful changes for their employees, they instead tell themselves that it's not really their fault – the bulbs are fine, it's just that that are so many defective lamps.  To fight change, they use their enormous financial and human resources to cleverly win vast, unrivaled political power, aiming particularly at utterly destroying the small, entrepreneurial folks making the special bulbs -- sadly, with a great deal of success.  Isn't it obvious that our policy should be to stop this outrageous and self-serving behavior?

 

But, you'll reply, it's hard to tell what type of bulb it is until it's placed into the lamp -- and given that the lamp has issues, sometimes the new bulb is no better than the bad one it replaced.  True enough, so again here the strategy is obvious: only replace the very worst bulbs, only do so when you have a reasonable degree of confidence that a better bulb exists, and lastly, have reasonable expectations. There will be some failures, and even the improved bulbs still might be weak and flicker a bit (but a lot less than before).

Thanks for getting me thinking about this...
