[A parent] wouldn't know of "guerrilla instructivists" because if they WERE known, they would be disciplined, transferred, or fired (or all of the above). I doubt if a single parent of the hundreds of students I've taught in the last 10 years would regard me as a guerrilla instructivist, nor do any of them, in all likelihood, know that I am using DI and other non-approved practices and curricula. I use the same lingo as everyone else, reporting on "shared reading," "making meaning" and whatnot, but I mean different things by those terms and use empirically-validated materials and methods to achieve the goals.
If I were to "come out," I would certainly be disciplined, probably moved to a position where I couldn't do any of the things I am doing.
....The fact is that methods, materials, instructional practices and use of teaching time is often prescribed at the district level, with no teacher input, even down to the last minute, and classrooms are searched for materials that are deemed inappropriate. Teachers have very little say in what and how to teach. They certainly can't do things like, junk Guided Reading and do DI (pdf file) instead. Teachers must follow the established protocols. They are lower-level employees, not independent contractors.
....Small districts tend to be more responsive to their clientele.* The real edu-nazis are in large urban districts, where they have a population that they can manipulate, ignore or work around, and who rarely are politically active and almost never in an effective manner. The administration runs the show. Teachers, like me, who strongly disagree with what is being done have to fly under the radar. Kind of like being in the Underground in WW2. You need a good "cover," and you must under no circumstances let on what you are actually doing.
Of course many who want to teach effectively throw in the towel and go to the private sector. I have given this serious consideration from time to time, but am stopped by the realization that in the private sector I will not be able to serve the population I do now. Every year I rescue a few off the Titanic, in spite of administration, curriculum and other impediments. Their parents don't know, the admin doesn't know (everyone can chalk it up to sudden "development.")
But I know.
So I am still here. But if you were a parent in my school, you would not know that I was a guerilla instructivist. You wouldn't know who the others are, either.
This reminds me of my days writing for New Woman Magazine. I used to lace my articles with all manner of rupturous, pro-male sentiments, but I'd cloak my heresies in proper language and tone and I'd usually get away with it.
* not in my experience, but I haven't been able to discover whether my district is unusual
