Charter School Growth

Yesterday, I wrote about some key questions facing the charter school movement. I starting thinking about how important these questions are in terms of the structure of our public education system. Here is what I dug up.

Data for 2009-2010 and 2010-2011 were unavailable. The percentage of total schools that are classified as charter schools is increasing by about .29% per year. This means that in 2011-2012, charters are projected to be about 5.63% of all operational schools (assuming a linear trend). This is a relatively small proportion of the total, but certainly more than just a drop in the bucket. And this proportion is growing larger each year.

 
In fact, charter schools have more than doubled since 2000, whereas the total number of operational schools has grown by about 10% over the same time frame. This impressive growth shows that charter schools have gained traction. Serious work needs to be done to analyze the charter model and how it can successfully be scaled up.

Questions about Charter Schools

A teacher friend recently sent me an Economist piece from 2009 about charter schools. Several extremely successful charters such as KIPP and Uncommon Schools have received a lot of press. However, the jury is still out on charter schools as a whole as much of the research is mixed about their overall impact. Below are two particularly relevant questions about charter schools that I believe are still unanswered today.

If charter schools are teaching a narrow curriculum and focusing on test preparation, that should become clear when data are gathered on high-school completion rates and college destinations. If they are excluding lots of pupils, that will be obvious too. And if the state education department co-operates by giving researchers access to data on its own pupils, it will be possible to tell whether charter schools are leaching talent from state schools—or whether the challenge they pose to incumbents improves performance across the board.

[...] The final charge against schools such as those run by KIPP is that their longer hours and the demands those place on teachers make them impossible to sustain, let alone replicate.

I am not proposing that I know the answers to these questions. I am simply recognizing that the area needs more research along with more time to follow the outcomes of the growing cohorts of "charter students".

2 Free MP3s from Amazon (Students Only)

Amazon is currently offering 2 free MP3 downloads for students. Worth checking out as they have a large selection second only to iTunes. Also worth checking out is this comparison of Google Music, iTunes, and Amazon Cloud player. The legal online music space is finally getting crowded. Will iTunes' prices eventually fall with the increased competition or are there substantial switching costs involved?

Tennessee Teachers Get to Play the Odds in the Evaluation Game

I will preface this post for anyone that is not aware. I taught high school math in Nashville, Tennessee for the last two years in the public school system. 

Tennessee is implementing a new teacher evaluation system this year. A NY Times article titled In Tennessee, Following the Rules for Evaluations Off a Cliff discusses the shortfalls of the new teacher evaluation system. I am aware of the challenge of measuring student achievement in classes like art, band, dance, and other subjects that don't have state tests, but this part surprised me:

For 15 percent of their testing evaluation, teachers without [test] scores are permitted to choose which subject test they want to be judged on. Few pick something related to their expertise; instead, they try to anticipate the subject that their school is likely to score well on in the state exams next spring. 

And more...

It’s a bit like Vegas, and if you pick the wrong academic subject, you lose and get a bad evaluation. While this may have nothing to do with academic performance, it does measure a teacher’s ability to play the odds. 

Although a learning curve is to be expected for states implementing new evaluation systems, allowing teachers of non-tested subjects choose which subject test they will be judged on is just a horrible idea. This blatantly bad policy needs to be scrapped, and the state department needs to go back to the drawing board. Why evaluate teachers on how their students do in ANOTHER subject? They have less incentive to teach THEIR subject well.

Sidenote: I am glad I'm not teaching right now in TN.

Where did all the jobs go...and when are they coming back?

More evidence that the most recent recession/recovery is a of a different nature than most. This graph shows the percent decline in employment levels over time for each recession since 1948. Not only has the 2008 recession had the greatest percentage decline, but it also appears that we will not return to the prerecession peak for some time. Notice the shape of the 2001 and 2008 trends vs the rest of the recessions shown. 2001 was not nearly as deep as some of the others, but it took a lot of time to get back to the previous peak. It looks like the Great Recession got the worst of both worlds.

Here is the original graph from McKinsey. They suggest an alarming trend, but I am waiting to see what happens in the next recession (although I'm hoping that isn't for at least another 10 years. If it is also followed by a jobless recovery, then I'll agree we are in serious trouble.

See my previous posts about the jobless recovery here and here. I'm not actively in the job market right now, but is anyone seeing signs of life out there?
