"Value Added Model" for Teachers is Poor Modeling

Thank you, Anthony Cody, for prompting me to send a message before the January 2 comments deadline to the Department of Education protesting their proposed use of so-called "Value Added Models" to evaluate teacher preparation programs. Here is what I sent, slightly edited to remove details of a specific case (the teacher in question was not me, by the way; I knew her, but not well).

To: OIRA_DOCKET@omb.eop.gov
Subject: "value-added model" for teachers is poor modeling

To Whom It May Concern:

I am a public school parent and have been a math and science teacher since 2009, when I attended a teacher education program after a previous career in the scientific software industry. I am writing to register my objection to the idea of using student standardized test scores to evaluate teachers or teacher training programs. Although I would be in favor of putting teachers, schools, or even education programs under closer scrutiny in cases where scores plunge or where consistent losses are documented over multiple years, the test score data on student growth is nowhere near precise enough to use fairly for these evaluations. It would be like basing the Consumer Price Index only on strawberry jam prices. I agree with many of the objections listed in this article: http://www.livingindialogue.com/duncan-brings-sham-vam-teacher-education/

Data on student performance also inevitably reflects far more than the learning experience the student had in the classroom. For instance, availability of computers at school could have a huge effect. For another example, [horror story redacted in which test scores plunged for some classes one new teacher had because of events the previous year, when she was not even at the school]. Should the teacher or her education program be punished for [redacted]?

Furthermore, the SBAC and PARCC tests are at a "beta" stage. We all know there are going to be problems with the rollout; how could there not be, with such major changes? By putting so much pressure on teachers to "achieve" on inevitably faulty first-round tests, you risk alienating some of your best allies. Many of us want to improve our teaching with Common Core standards, and we want high-quality tests that will give us some information about what our students are learning and what we still need to improve in our instruction. Help give us a way to give feedback on the tests and improve them without the horrendous conflicts of interest you introduce when we and our education programs are punished for poor test questions or design that are likely to disproportionately impact our ELL, SpEd, and non-white-middle-class students.

I do believe that over time, education programs that produce the most valued teachers (and, of course, the most value for their teacher students) will be those that have the best record of placing teachers in schools. I completely approve of efforts to increase reporting requirements for programs of education on teacher placement, and could support programs gaining an advantage if they consistently supply teachers to high-needs schools. 

I hope you will carefully consider all points of view and ensure that any data-driven analyses are actually using high-quality, relevant data.

Sincerely,

Diversity and the MathTwitterBlogoSphere (MTBoS)

I'm catching up on my MTBoS reading after the holiday rush and the post-holiday sluggishness. Today I read Michael Pershan's Year in Review blog post, in which he referred back to a sort of self-reflection from October which I unfortunately missed at that time. If you like Michael's writing, which I do, it's all thought-provoking and engaging, but there's one comment I wanted to highlight and write about:

A quick note about race: there's no real mystery about how to diversify the MTBoS or TMC. You need to seek out teachers of color and invite them to join your circles.

This can be done bluntly or subtlety, depending on what the situation calls for. But if you're interested in twitter being more diverse, then go actually search for teachers of color to follow and then follow and chat and RT them and such.

It bugs me that people treat this like it's some grand puzzle to be cracked. It's just hard work.

I don't especially know Michael, but I can vouch for him on this: both that he practices what he preaches, and that it made a big difference to me, a 49-year-old white woman who can be a little gun-shy about male-dominated professional spaces. I joined Twitter and started this blog this past summer. I haven't been blogging or even tweeting much lately, but I am fully intending to pick up the pace more in 2015, especially over the summer.

The fact that I have been and will be tweeting and blogging instead of just lurking or wandering away is due more to Michael than any other single individual, and it is from just what he said here: he noticed me, paid attention to what I said, engaged in conversation with me online, was one of my first followers, and recommended others to follow me. This kind of welcome, from him and others in the MTBoS, and the active, lively, respectful conversations among women and men of diverse ages and teaching roles, kept me on Twitter at a time when I easily could have felt there was not much of a place for a 48-year-old woman in this new(ish) space whose most famous citizen (at least to me) was a young white guy. If we want to hear from all kinds of teachers, we should make sure they know they're not tweeting into a vacuum, and the best way to do that is to respond somehow.

One conversation from my first few weeks on Twitter stands out in my memory, enough that I just went back and dug it up to make sure I had it right. It was about one of Michael's posts on feedback. I commented there and, I think, tweeted something early on and was included among the names in the tweets for a few rounds. My name got dropped after a bit, which didn't bother me, but I kept reading the conversation because it was interesting. Then all of a sudden this happened:


I was stunned, in a good way, but I don't think I answered either of those remarks (till now, obviously) because I had no idea what to say. I felt like I didn't understand Twitter culture enough (I still am not quite sure of the etiquette of barging into threads when your name's not on the list, though I do it now anyway); I felt they had nothing to apologize for about dropping me and didn't know how to say that and appreciate the thought at the same time; I worried anything I would say in response would sound patronizing (wow, you're a young white guy and you're aware of sexism? gold star for you!). All of those things are still true, but I'm going ahead and saying something now because it made a big difference to me that they noticed and cared that including me would change it from an all-male conversation.

Within a few weeks, I had found plenty of women and men on Twitter to follow (and others to read frequently even if I didn't follow them), some of them followed me too, and I was hooked. I've been cautious about following too many accounts for fear of getting swamped, but after reflecting on my own experiences, I'm going to try harder next year to seek out and follow teachers who I wish I could hear more from, not just wait till their accounts are full of interesting posts... which might never happen if they are tweeting into the void.
