More soon on how the scoring layers work. 📷

Most reading apps let kids race forward while quietly forgetting everything they "learned" last week.

We built Dojo Sparks to avoid that problem.

If you're struggling, you don't get new lessons, you review. Foundations first. 🧵

[Dominick Bellizzi @dbellizzi]

Your path is mapped out, but you move when the foundations are solid, not when the clock says so. If reviews pile up, new content waits. Practice first.

Waymo data shows an 85% reduction in injury-causing crashes. The moral case is to accelerate adoption, not slow it down.

We already know how to tax digital rides — every major city does it. We don't need to panic.

There's a proposal to tax driverless cars before they even cause congestion.
But that means keeping human drivers on the road longer — and they kill 40,000 Americans a year.

Preemptive policy has a body count.

[Works in Progress @WorksInProgMag]

The world is heading towards permanent omnigridlock. Self-driving cars will force people traveling to work or going to the hospital to share the road with people who are sleeping, working, or just socializing with friends. This can only be prevented by taxing Waymos now. New from @bswud.

I wrote about my exercise journey here:

I got a second-degree black belt in Aikido, trained six days a week for a decade, then lost my whole routine when my first child was born.

[Dominick Bellizzi @dbellizzi]

It took a beta test for a discontinued fitness device and an LLM to get it back. I need to keep adapting to find something that sticks at each phase of life, luckily the tools keep getting better.

@JayKloppenberg @ninja_maths @exojason @_MathAcademy_ @justinskycak I found this counterproductive. My daughter is going through Math Academy 5th grade and doing well. Twice she was hit with a large negative XP. Both times she didn't understand the material and needed more help. I don't think this UX is helpful for child or parent.

No single math curriculum is enough.

After homeschooling my kids for several years, I've learned that even comprehensive programs have gaps. Different children need different things at different times.

[Dominick Bellizzi @dbellizzi]

Beast Academy for conceptual learning. Math Academy for drill practice. Physical flashcards and whiteboards for portability and games.

The system keeps evolving. Next year we're moving to AoPS for pre-algebra.

5 years ago, I would have laughed if you told me I'd be homeschooling my kids.

We had no homeschool background. We were both public school educated. We didn't know anyone who homeschooled.

Then COVID happened.

[Dominick Bellizzi @dbellizzi]

Something unexpected happened: I loved it. She loved it. We realized we actually enjoyed teaching our kids.

It was a high-stress decision. I worried about everything. All of that was overblown. 3 years in, my life feels more integrated with my kids' lives.
