Yes and no. The algorithm runs with historical student data and therefore only considers students using the bus system in order to compute the effects of school start times on transportation. On the other hand I think the district had plan

I am no specialist of children health, but my understanding is the following: I guess starting too early is never good for any child, but there is something specific with teenagers that makes it a lot worse. There is much more medical liter

Yes incremental changes looks like a good solution. I think it is hard to do it with the delta minutes changed, as you could have dramatic consequences on the costs (the ripples on the transportation systems can be quite surprising, in that

We talked about it at some point, and it seems like a good idea. There are two main issues with it: first it can be hard to do a step by step change that is (a) fair (how do you choose the first schools to change?) and (b) works for every s

That could be a way to do it, and Boston decided to do it all at once. I think their reasoning was the fairness of the process (it's hard/unfair to use beta testing on public schools). Also, it is such a hard change that maybe it

Thanks for sharing! I am sure more engagement is always a good thing! One of the tricky tasks of BPS is to make sure that this engagement is "balanced", i.e., everyone's voice is equally heard. And you can imagine how hard th

per transported students. The transportation cost are more than 100 million per year.

This can happen and did happen before. Maybe being suspicious of an algorithm is not a bad things, we should have extremely high standards for them ! My hope is that some people will just have a better view of how complicated this problem i

No, as far as I know having later school start times for high schoolers was the main objective, and that was the strongest one in the solution that was chosen by Boston when they used our algorithm. There has been a lot of research on high

No, although the A-lab have a lot of interesting projects. We are part of the Operations Research Center: https://orc.mit.edu/

It's true that it was fast, maybe too fast, although the district was planning this conversation for more than 10-20 years. But even if it has not been implemented, the debate itself may have been worth the trouble. The complex problem

That's interesting. Our approach is based on Mixed Integer Programming and Generalized Quadratic Assignment.

We submitted it to a journal that has a fast review process, and we are towards the end of it. We did not think soon enough to put it on arxiv, and we should be able to do it soon (it requires some editing to remove the journal-specific thi

Thanks! I am actually very excited about this thread, our main hope is for this project to start a conversation !

The process went too fast to be entirely transparent. Boston tried to communicate as much as they could, and anything can be requested (Freedom of Information Law). We also have a paper that should not be too far from publication that detai

Yes, Boston Public Schools has the second highest transportation budget per student in the country as a result. If I remember correctly it is ~25$/student/day. But one could argue this is the price to pay for increased diversity.

I think "novemtrigintillion" was just a harmless joke about this very large number of possibilities, nothing too serious about it, I also had to Google the word I doubt anyone knew it. > (1) Supervise the children of working ad

by lodrein 8y ago
Yes it did. What you are suggesting would be politically very complicated to implement. Also, one need to take into account the characteristics of the district: https://www.bostonpublicschools.org/cms/lib/MA0190646

I think changing the start times is something the district had wanted to do for a long time. Therefore once the research and the algorithm suggested it was a good idea, they quickly jumped on board. Now I am sure we have done some communica

That's a great question, that I asked myself a lot. I think this project was useful because it started this debate and brought more information to the table. For example, I found that a lot of people did not know how much the start tim

I agree that the role of politics is important, and maybe it is for the best if it can help create a conversation. One of the main objective of this particular project was to make a complex problem more accessible to a general audience, so

It makes sense that it can be easier to be misunderstood by a human than by a robot. And what about the case when any decision will always be bad for some people? I would argue that using (at least partly) an algorithm can add some fairness

It may seem feasible on the long run. Indeed, it can be easier for the parents of the new children to adapt their schedule. But it can be very hard for the parents that previously chose the school (partly) because of its start time, and ada

It is typically very hard for the parents when we change a school start time, sometimes even when the change is small. Doing small changes can help, but it is so politically complicated to change the school times that some districts prefer

I am one of the two PhD students that conducted this research with Boston Public Schools. I'll be glad to answer any question you may have.
