Ask HN: How are you innovating in ed tech?

I'm building Quill.org to help students become stronger writers and critical thinkers. We're turning the powerful writing strategies detailed in this piece into free and open-source learning tools that can help millions of students: https://www.theatlantic.com/magazine/archive/2012/10/the-wri...

We're now building new critical thinking tools that help students build logical claims, use precise evidence, and articulate their own ideas. If you'd like to learn more, my email is in my HN profile.

I am working on a couple of ideas, all applicable to in-school or remote learning:

1. How to reduce teacher workload outside of school

2. How to easily introduce mastery and differentiated lessons into mainstream/c-c planning, instruction and assessment

3. How to introduce project-based learning into mainstream/c-c planning, instruction and assessment
