Incentive Pay for Teachers

This report is from India; it's entirely possible that it's completely irrelevant to US issues. Still, it's also possible that it's not irrelevant at all: Shout it from the Rooftops! Performance Pay for Teachers in India
Students who had completed their entire five years of primary school education under the program scored 0.54 and 0.35 standard deviations (SD) higher than those in control schools in math and language tests respectively. These are large effects corresponding to approximately 20 and 14 percentile point improvements at the median of a normal distribution

Second, the results suggest that these test score gains represent genuine additions to human capital as opposed to reflecting only ‘teaching to the test’. ... ...

Augmented Reality & Education

The Most Powerful App for Education
Bill Shribman is a photographer and a Senior Executive Producer at WGBH Public Television where he and his team create websites, games and apps for popular kids shows such as Arthur, Martha Speaks and Curious George. .... Take a tour of gesture-based games, augmented reality apps, and an app that helps kids with autism infer emotions through photos, and you may agree with Shribman that the most powerful app for education may be the camera.
The station is WGBH-TV and they blog their apps at Apps | WGBH Kids Interactive Group; I don't know that I'd say that the app is the camera, but I would say that apps using cameras (and today's tilt/acceleration/location/etc sensors along with tomorrow's everything-we-know-how-to-sense sensors) can become part of reality in a way that apps stuck with pre-defined data never could have done, and not only for the smaller kids.


Or then again, maybe not.

Networks of Imagination

Ken Bausch mentioned this last December; The Global One-Room Schoolhouse: John Seely Brown | DMLcentral
In this video, which contains the highlights of his “Cultivating the Entrepreneurial Learner” keynote at the 2012 Digital Media and Learning conference in San Francisco, he introduces the fascinating notion of “a global one-room schoolhouse through networks of imagination.”
It seems to me that this is quite compatible with Sal Khan's vision (and book) that I've mentioned a few times, but it's an interestingly different point of view. I'm inclined to see it as a mix of Khan with some of Yong Zhao's World Class Learners, but that oversimplifies as usual. I do see him as detecting and approving a trend towards tools like Scoot & Doodle | Get Creative Together, which has just received fairly major support from Pearson among others.


Well, maybe not just kids, or just play; I'll add some emphasis in a quote from the GeekDad report on Scoot & Doodle: Makes Google Hangouts a Collaborative Playspace | GeekDad | Wired.com
essentially, it is an app that works with Google+Hangouts and lets you type, draw and engage in a visual and tactile way – as well as through video and voice. In my use of it I have found it to be really stable and offer a fluid and worthwhile experience whether with my kids or with business colleagues. Like many startups there appears to be more potential applications than you can imagine; however, kudos for both the Scoot & Doodle team and Pearson for seeing the potential of this in the education and learning space.
And I certainly approve of the idea that education works off study groups that fit in a Google+ Hangout. That works.

Or then again, maybe not.

Other School Analogies: Day Jail?

School isn't just about learning; it's also about signaling that you've learned, of course. Beyond that, it's about making society work, in such a way that parents can do what they need to do all day. Arnold Kling, in The Dark View of Schooling, notes
Bryan Caplan thinks that schooling is not about education. He thinks instead it is about signaling.
Bryan’s view is benign compared with John Holt.
society demands of schools, among other things, that they be a place where, for many hours of the day, many days of the year, children or young people can be shut up and so got out of everyone else’s way. ... That is an important part of what schools are for. They are a kind of day jail for kids.

I do believe that technological improvements can make signaling a lot easier, in K-12 as much as in How testing could transform higher education:

having a well-calibrated measurement would put a lot more focus on learning the material and much less on how you learned it. No one will care too much which book you read, which online class you took, or what exercises you did. Those are all just ways to learn. Second, this would truly democratize education—the self taught Bangladeshi is on equal footing with the legacy Harvard admittee.

If you want to know if a kid has grasped 10th grade math, start him on the Khan Academy 11th grade sequence and see how quickly he reaches "mastery". Of course you probably need humans to rate English composition, if not reading comprehension, but you can go a long ways without adult humans involved -- let ten kids write short essays to summarize some information, each of them answers ten sets of multiple-choice questions, and they get comprehension scores based on how well they answered, but composition scores based on how well their readers answered. (Is this a bad idea? Probably; I just thought of it. There are lots of possibilities.) The testing tools for this probably won't come very quickly, and they won't come at the same pace in all subject/skill areas, but they're coming. I'm less confident that we'll get a substitute for the "day jail for kids." Many parents will want to know that their kids are somewhere being supervised -- the sort of "off in the woods, probably building a dam" that went over well enough in the late 50s (when I went along with my elder siblings) is probably gone forever.

Or on the other hand, maybe not.

All that Jazz -- Education Analogy

Alex Tabarrok, economics professor and co-founder of the online Marginal Revolution University, comments on Online Education and Jazz
there is something special, magical, and “almost sacred” about the live teaching experience...It’s even more true that there is something special, magical and almost sacred about the live musical experience... and yet by orders of magnitude most of the music that I listen to is recorded music.
In The Trouble With Online Education Mark Edmundson makes the analogy between teaching and music explicit:
Every memorable class is a bit like a jazz composition.
Quite right but every non-memorable class is also a bit like a jazz composition, namely one that was expensive, took an hour to drive to (15 minutes just to find parking) and at the end of the day wasn’t very memorable. The correct conclusion to draw from the analogy between live teaching and live music is that at their best both are great but both are also costly and inefficient ways of delivering most teaching and most musical experiences.
I think that's true, but I think that maybe he's missing part of the point of his own work and that of other online services: online teaching environments and live teaching environments both offer opportunities for interaction, and for student improvisation. Online teaching can (and probably will) get better with time, the techniques are reasonably cumulative. The approach of, say, the Berlitz LP records that helped me learn Spanish fifty years ago is still available online -- it is now supplemented, not entirely replaced, with the game-like approach of Rosetta Stone which one of my sons used recently, to help get ready to go to Nicaragua with some old friends from HCS. Live teaching from a great teacher is not cumulative in the same way (I was a worse teacher than most of my teachers, no matter how hard I tried.)

If MOOCs were going to be "everybody watch the same lecture and then take the same exam", that would be of some value, and the use of a great teacher could increase that value greatly...but that's not what's happening. On places like CourseTalk | MOOC Reviews & Ratings you can learn who is teaching what and how, and how well it worked...you can learn about online courses, yes. But at the same time, when you interact with software like that of the Khan Academy, that software is learning about you. In fact it can pay more individual attention to you than any human teacher can, outside of the traditional 1-1 ideal, and it can eventually improve on that 1-1 ideal because it can try out different approaches on millions of students -- different explanations, different experiences suggested by thousands of different teachers and students. It can note which works for whom -- and it can compare you to more somewhat-similar students than any 1-1 human teacher can ever make notes on.

Will it ever outdo human teaching in every respect? Gee, I dunno. But it can certainly outdo human teaching in many respects.

Or then again, maybe not.

Apprenticeship Models

I tend to focus here on geeky approaches to education, but they're not for everybody. Maybe not for most. The "Conversable Economist" writes on Taking Apprenticeships Seriously that
"At ages 15 to 16, in Switzerland, about two-thirds of every cohort enter apprenticeships.... Apprentices in fields from health care to hairdressing to engineering attend vocational school at least one day a week for general education and theoretical grounding for roughly three years. On other days, they apprentice under the supervision of a seasoned employee. ...
In Germany, about 25 percent of students go to university, and apprenticeships employ another 53 percent. At 16, they sign on for a three-year stint in one of 350 occupations. ...
Other western European countries use variations of the Swiss and German model. ... The United States is an outlier: By international standards and official definitions, it has virtually no vocational education and training program."
Is there an effect on youth unemployment, and thus on career-starts? Well, our youth unemployment is much higher. This might be part of why.

Or then again, maybe not.

CAC Done; Do You Feel Lucky?

The "Community Advisory Council" (or are we a Committee? I forget) had its final meeting last night, to look at the documents mentioned in the last couple of posts. My initial summary, as I said in the meeting, is that the "What If" program document suggests a economy-of-scale savings of $717,000 per year, while the "What If" transportation document suggests that in order to get the kids together for their economy of scale, we need to spend $642,000 extra per year on buses. That's a yearly savings of $75,000 out of $27,000,000 for the combined districts. Everything else we're talking about (millions of dollars in benefits) seems to be coming from the state incentives for merger -- incentives which mostly run out after fifteen years, even assuming that they don't stop earlier than promised.

Hmmm... Well, I would like to go a little further than that initial summary.
  • The $717K savings looks pretty solid.
  • The $642K extra cost is a pretty big gamble.
  • I don't entirely trust the state benefits.
  • There are also some genuine non-financial benefits to consolidation.
  • I don't think they're as important as many think.
  • I have another proposal. :-)

The -$717K program proposal strikes me as well-done; this is where our SES Study Group shows off the fact that they really do know what they're doing, putting together something credible and credibly saving a bunch of money at the same time. No criticism from me -- but I understand where some critics were coming from, having hoped that the program could have more in it.

The +$642K transportation proposal is understandable, and as they said they asked the local experts how to manage it and it probably can't be done much better though experience will improve it some. BUT -- As Susan Marafino said in the meeting, that $642K will rise if fuel costs rise: consolidation is a bet that they won't. As I said in response, fuel costs might not rise: natural gas prices have been falling and we are seeing increasing use of natural gas vehicles; on the map you'll see one station in Utica, three around Syracuse, three around Albany, one in Poughkeepsie...prices may fall. Or not. On the other hand, the past fifteen years have seen gas prices quadruple. On transportation cost, it comes down to this: Do you feel lucky?

Increasing transportation is a small gamble in another sense. The National Highway Traffic Safety Administration (NHTSA) says
An average of 24 school-age children die in school transportation-related traffic crashes each year (11 occupants of school transportation vehicles and 13 pedestrians).
That's not many; it's not one of the major risks of childhood, it's not even a major part of the risk of vehicular death in childhood. But it's a bigger risk than random shootings at school unless Sandy Hook is the new normal; if you're worried about school shooters, if you're worried about causes of death in general, you should worry about this a little more.

The transportation plan also involves another cost, which some will think small: as I said in the meeting, we'll have some hundreds of kids spending about an hour each day (two twenty-minute rides and maybe ten minutes waiting for each, morning and afternoon) which they do not now require. Kids from Hamilton will do this for three years, kids from Morrisville will do it for four. That's not a gamble, it's just a little sad. And boring. (But it's better than exciting...gee, I remember hanging on to the bus' door handle going home from my own elementary school, with one foot on the step and a couple more kids on the steps ahead of me...boring has a lot to be said for it.)

The state benefits are the big deal here; they don't just handle impacts like the first year of extra bus usage, they pay off millions of existing debt and provide other benefits. Do they? Well, maybe they do, before they come to an end and leave us, lucky or not. But there is a New York State Budget Crisis Task Force, and they seem to me to be saying that
the money available to the state may suddenly decrease, whether from renewed recession or from financial companies moving their operations to lower-tax regions; their incentives for doing so have risen.
... Aid to K-12 education is by far the biggest portion of state aid ($23 billion) and is the largest item in the state budget.
When you make big plans based on promises of future state aid, you are assuming that the state will be able to keep its promises. The state is in trouble, unprecedented trouble in some ways; that trouble is almost certain to get worse; that trouble might suddenly get much, much worse; K-12 aid is the biggest chunk; New York State K-12 education is more expensive than anybody else's (except Washington, D.C.?). If something's gotta give, it's likely to be us. Do you feel lucky?

Now, there are genuine non-financial advantages to consolidation. If you scroll down to the bottom of this page, you'll see a little Javascript widget about grade sizes that says
Here's a test of the importance of grade size, which is roughly doubled by a merger of equal schools. Suppose we have a grade of size gradeSize (say, 45) from which we want to select a Latin 4 class of at least 10; it won't be offered without 10....
I suggest that you put in your own guesses about grade sizes for HCS and M-ECS, now and fifteen years from now. Put in your own guesses about the percentages who'd like Latin 4, advanced chemistry, or jazz band. I believe you'll see that consolidation makes it easier to offer advanced courses, when schools require minimum enrollment the way ours do.

I also believe that minimum-enrollment policies will become less common in a world of the Khan Academy and Salman Khan's One World Schoolhouse, so I don't think grade size is as important as I would if I thought minimum-enrollment policy was a necessary part of school. (see footnote.) Still, the benefits of consolidation are, or might be, quite real -- but so are the costs, and consolidation is a gamble that the costs will not be too much higher than the benefits. Do you feel lucky?

I have another proposal. Last night, for the first time, I heard someone say that the M-ECS school could handle many more students; that it had handled many more students. The SES response was that it couldn't do so with the current usage pattern as defined by the Board, which is certainly fair enough. But suppose that this is true. If so, I would propose a different kind of merger, one which is probably politically impossible for excellent reasons, but still worth a thought. Leave every HCS student at HCS; close Andrews Elementary completely (this will save a whole lot of money, really), moving all those students a little ways north; now go to Hamilton with Morrisville's 12th grade, 11th grade, 10th grade...9th? Does it fit? It might...and the advanced classes can go on, even with minimum enrollment policies, and Morrisville students will be able to sign up for Colgate courses, and so on. Nobody loses, everybody wins...or not, depending on what they care about. And "what they care about" is important. Indeed, that's what it's all about...I don't think this will happen. But it's worth a thought.


footnote on minimum enrollment policies: My own AP classes were mostly independents; I think I had two classmates in AP English, but my own high school (it was smaller then) wasn't a good candidate for consolidation. In any case, I don't think 10 is a good minimum class size; I think it's bigger than most study groups ought to be, even considering that I think most study groups should probably be virtual -- maybe two students physically present, with webcams and big screens to connect up a virtual table, and a responsible adult who is not a "teacher" present somewhere nearby, while tutors connect mainly online... but that's just one image among many possibilities. School is changing. Prediction is hard, especially of the future. My vision is almost certainly wrong. Consolidation commits you to a single vision. I'm skeptical.

footnote on district comparison: I've tried to collect some district comparison data at this blog's disorganized companion website as well as around here. It seems to me that consolidation commits you to having a single vision; you have to agree with people about what kind of lives your kids are likely to live (and then, of course, you have to support your kids with whatever they decide for themselves, which won't resemble your visions very closely.) That's hard. Of course you might find that you really do agree on priorities. Or not. Do you feel lucky?

March 12 Update on What's Next: As I understand it, the SES Study Team will now finish their write-up as a submission to New York State, which paid for the study and expects a document. Meanwhile, the Hamilton and Morrisville Boards of Education will be talking about it. Then it goes public, as they say here:
Adopting the merger is a three-step process.
  • Boards vote to move the process to an advisory referendum or "straw vote."
  • The communities hold a straw vote. If this passes, the results are sent to the education commissioner who authorizes a statutory or final referendum.
  • The communities hold a final referendum.
(Or then again, maybe not.)

HCS--Questions on What Ifs

Ferdinand von Muench, on looking at the three "What If" documents of the previous post, asks questions for each of them:
FINANCES
1) Is it fair to say that excepting incentive aid (which decreases over time and runs out after 12 years) a combined school district would incur nearly as much in additional transportation cost ($ 640.000/year) as it would save in instructional and administrative staffing cost ($ 720.000/year) – i.e., that in the long run we would perhaps save a little money but would mostly be shifting resources from education to transportation?
2) The Governor’s budget proposal for 2013/14 includes a 10% cut in the line for operating reorganization incentive (page 8 of the PDF). How might such a cut (or similar cuts in the future) affect the financial picture of a school district merger?
3) State aid has recently been volatile and affects districts differently. How would a 1% cut in state school aid affect the current and the projected future budgets of the two districts?
4) Studies show that after a merger the real estate values of the wealthier previously independent district typically decline. Has this been factored into the projected financial picture?
5) Is it true that the former Hamilton School District would contribute roughly 60% of locally generated tax dollars, and the former Morrisville/Eaton School District roughly 60% of the students, to a merged district?
TRANSPORTATION
6) What are the current and the projected future number of transportation miles per district and per student?
7) What are the current and the projected future amounts of fuel for transportation?
8) How would a price increase of 10 cents per gallon of fuel affect the current and tbe projected future transporation budgets?
9) NYS transportation aid has been trending downwards. How would a 1% cut in state transportation aid affect the budgets of the current and projected future districts?
10) The document states that "the goal is to reduce the current longest ride of a child on bus which is about 75 minutes." What is the current average time on the bus in each of the two districts, and what would it be in a future district? And how many kids who can now walk or bike to school would have to take a bus in the new district?
PROGRAMMING
11) How would a middle school day that ends at 3:30 in Morrisville affect the ability of middle school students to participate in extracurricular activities together with high school students (e.g., JV teams, musical actitivites etc.), since the high school day would end at 2:30?
