There's a lot going on here. Most of it boils down to a concerted, decades-long project by half the country to defund, dismantle and destroy public education. This has infected every layer of education including what goes into textbooks. The Texas Board of Education has typically had outsized power here as they've mostly been the largest single purchaser of textbooks. But also we have the likes of Robert Maxwell who basically owned textbook printing [1], before "falling off" his yacht.
But the part I want to concentrate on is the education part and the role of tech. Anyone who sells to large bureaucracies like state and federal Education Departments will tell you the skill is in managing the procurement process. It's getting your claws in more than it is in delivering results. Any results tend to be more manufactured than not.
So contracts get signed with states and school districts that will require them to use a particular product, even if it doesn't work. We know how this goes too. Whoever was in charge of that decision will then tend to leave their job and go work for the seller. Shocking.
But we know what works in teaching and it's direct instruction [2] but you don't sell tech platforms or iPads or laptops that way. As a result we now have a disturbing number of people who have never read a book and really can't read a book, going so far as the students of elite colleges [3].
Likewise, we see Education PhDs who won't make a name for themselves pushing ideas from the 1800s. They have to come up with new methods and this was kind of a disaster for literacy [4], which people are finally waking up to as we go back to the 1800s method of phonics eg [5].
But it's hard to succeed when half the country wants the entire system to fail.
