This is a very thoughtful response! Thank you. I'd love to chat with you further, if you'd like to reach out directly to me (just use the demo form on the site). We are launching Bloomy this…

Great points! Agreed on the distinctions. With enough data we should be able to identify lots of cool things about mastery.
comment
These are really thoughtful points. Thanks for sharing them. I'd love to check out your code. The percentage mastery threshold on Summit may indeed be quite high, but the Summit also comes after …

Thanks for engaging! Let me clear up some inaccuracies lest others misunderstand. First, those are all verbatim quotes from the educators. They were taken directly from letters of reference (which I r…

Thanks, that's very helpful feedback! We'll improve this.

Thanks for engaging! Our passages are a mix of public domain passages and in-house authored material which are specced to a long list of requirements. This allows us to create passages spanning a rich…

Thank you! It's an interesting time for sure. In the face of all the headwinds, there are also some interesting tailwinds and opportunities: -Shrinking budgets forcing reevaluation of longstandin…

I'll check them out, thank you for your suggestions!

I agree that how we approach the market will be the difference between being successful and failing. At this stage, we’re focused on finding early adopters who have the autonomy to try a different cur…
comment
Thanks for the thoughtful comment. We’ve actually had a few school districts ask about paper workbooks, so this is already on our radar. Right now, students can move at their own pace and use a notebo…

We ran a pilot with roughly 150 students in grades 6–8. Students who used Bloomy for one hour per week averaged 1.8x their expected winter-to-spring growth on NWEA MAP. Our team was understandably ene…

Thanks! I’ll have a read. Appreciate your taking the time to source and share these.
comment
There are many problems to solve within education! To say there’s only 1 aspect would be a massive disservice to the ~2 decades the average person spends going through a school system. Some studies es…

This is interesting, can you say more?
comment
Funny you say that. We actually just released a voice mode that allows students to engage, interrupt, and even switch languages. I'd love to design this to a greater extent throughout the experie…
comment
Thanks for the support! On motivation: we have something called Bloomy Bucks. Kids earn these for getting questions right, mastering skills, and being consistent. They can then redeem them for privile…

Yes—and the whole hypothesis here is that teaching could be more efficient than it currently is!
comment
I've been extremely inconsistent in my dashes today as I flip between different devices :)
comment
Good questions. I like that you're digging into the mechanics. First principle: BloomyBot does not proactively engage the student unless they make 3 mistakes in a row in "Climb" (the pr…
comment
I misread this -- yep I agree with the original statement!
comment
I just posted something pretty relevant to this in a different comment. Totally agree with the dangers. 2 important points: 1. Not all AI is the same. I see 2 MECE categories in education: AI that doe…
comment
I empathize with the screen time concerns - the reality is most kids in classrooms are already on screens, which are doing very little to move educational outcomes (from what I can tell based on the N…
comment
I've personally both had and seen great success with the Anki approach for specific terms (e.g., vocab flash cards). Spaced repetition is built into Bloomy based on similar principles. A little h…
comment
I have a slightly different perspective based on how I've observed schools use Bloomy. Focused use of Bloomy has allowed teachers to deliver higher-touch support to students who need it most (it …
comment
I love self-learning. I read a lot of books as a kid (at one point my dad even got mad at me because I was ignoring him while reading yet another book). At the same time, I believe -- and have seen fi…
comment
I like that you're touching on a bit of Horizon 3 education here! I agree that the model is antiquated and is long overdue for an upgrade.
comment
Great point. The responsibility and consequences of the tech (both bad and good) rest upon the humans who designed it.
comment
AI is certainly not a monolith. Many aspects and use cases of AI are dangerous -- fully agreed. As others have commented, it would be better if we could give every student their own personal tutor. Un…
