Hi HN. My name is Jurgen. I'm the Co-Founder and CTO of amy.app
About one year ago we couldn't secure any more funding and had to shut down the company after 7 years. During that time, our content team generated about 25000 math exercises. Each exercise has a step by step solution. Furthermore for each step it includes pedagogically valuable mistakes students might make.<p>Given that content is pedagogically sound and human curated it might be useful to someone. It could be used for things like AI training (after all it resembles a chat) or for creating individual math exercise to print them on paper.<p>If anyone has some pointers I would love to hear them
- Here is a content explorer: https://curriculum.amy.app/ToM (this does not includes the mistakes part)
- That's the landing page: https://www.amy.app (you can try it by click the demo button)
- This is an SAT specific version: https://sat.amy.app<p>Please find my contacts in my HN profile.<p>Thanks again!
Anecdote time: [Hi from Argentina!] During 2020 everyone and their dog made a similar project with Moodle (not as nice, but easier to implement in a few weeks). At the peak, I had to use at work 4 Moodles and my wife 4 Moodles, and only 2 were in common. A friend has like 5 or 6. Note that all of them were in the same University! And all of them had a slightly diferent configuration so transfering quiz from one to another was sometimes a problem.<p>I participated actively building questions for one of them before the pandemic, and we copied a lot of the stuff to one or two of the others.<p>I don't know about selling this stuff, but I think it will be difficult.<p>Anyway, I have some feedback about the questions. I tried the free ones. In the calculus example, when the computer replaces<p><pre><code> something + 7x + c
</code></pre>
with x=-4, it uses<p><pre><code> something + 7 × - 4 + c
</code></pre>
We usualy prefer that the students use parenthesis arround the negative values like<p><pre><code> something + 7 × (- 4) + c
</code></pre>
In a midterm we will put a warning, but not substract points if they don't use the parenthesis. Most of the times the students don't write the × and the equation is confusing.<p>Also in the next step<p><pre><code> something + - 28 + c
</code></pre>
I strongly preffer<p><pre><code> something + (- 28) + c</code></pre>
Those questions sound really valuable.<p>Off the top of my head<p>- Sell them to another educational company or charity. I can think of a dozen maths websites I used while at school that might want to pay for that content.<p>- Use them to train an ML model that generates new questions, then sell that (btb or btc).<p>- Sell them to parents and students as exercises.<p>- Sell them to teachers as exercise<p>- Sell a service to schools that allows access to them (either a directory or a "click to get a random exercise!" kinda thing).<p>-Sell a service that produces new mock tests with a single click, and that as a data source.<p>While I'm British, not American, I saw and used plenty of services that sold questions and worksheets. All were technically hideous.<p>I finished my A levels (high school) 6 months ago fwiw.
