That has certainly been a recent trend here! I wonder why that is. As an educator, I can offer my own hunches:

- The COVID pandemic forced students' and teachers' experiences into the open; schools still haven't returned to "normal" since 2020

- Folks here are trying to grapple with the roles technology can play in learning and in our education system

- Software engineering and related fields require a decent education; perhaps folks are worried about who may be prepared or under-prepared for the field in the future

American public school system is broken. It is feast or famine. Many teachers are bad at teaching. Many schools are no more than daycare centers. Many students are not interested in school. I don’t know what the answer is. The fact of the matter is many American universities also have fundamental problems. The university seeks prestige via research and publishing as many articles as it can. Educating students seem to be an after thought.

algebra is taught comparably badly in many other places...
