Digital textbooks are trash. I've noticed even using them myself as an adult in grad school, the material doesn't sink in as well.
We've basically banned the use of screens for our kids, with the exception of 1 hour / day of TV or video games. They won't be getting a phone until at least high school. Hoping to avoid the zombies that MCM and Lars are dealing with.
We really dislike how much the tablets and such are used in their school, as is... Though some of the teachers are starting to push away from it, at least the non lazy ones, I've noticed.
We have friends with similar aged kids that pulled their kids from our school and are sending them to a school with zero screen usage - outside of specific actual tech classes.
This has been known for years of course, rich families send their kids to private schools that offer zero or very limited screen interaction... Particularly for K-6.
