I worked in high schools, middle schools, and elementary schools before I retired a few months ago. In my experience, it was easily over 60% of our work that relied on AI. We used it for lesson plans, activity planning, scheduling, meal plans (especially for students with dietary needs), presentation layouts, parent communications, fundraising letters, and even board meeting speeches. Every teacher and aide I worked with used AI regularly. (Obviously, we didn't blindly use it without vetting/cross-checking. We used it more like a personal assistant. We still taught, graded, interacted, led, etc. personally)
As for time saved, I’m not sure. Any time it saved was quickly taken up by other responsibilities. Honestly, I had to use AI just to finish all my assigned tasks each day. Even then, I still found myself working after school and at home.
I’ve had a lot of jobs, but teaching was by far the hardest. I loved the kids, though, so it was worth it. Even though I’m retired now, I still miss them. I’m actually thinking about going back as a substitute teacher just because I miss everyone so much.
PTB or CLM. But it's .world, so of course they suck.
