My wife worked, still does some consulting for Detroit Public TV. In June of 2020 they got a call from one of the local school systems about using one of their channels for teaching. That led to a collaboration with the other Public Stations across the state (all but Detroit owned by Universities) to form the Michigan Learning Channel, offering basic reading, math and other programs on one of their over the air channels. They also hired coordinators to work with the local stations, schools, libraries with supplemental tools for teachers and parents. It's gotten rave reviews five years into the project (my wife is no longer involved), as well as receiving bipartisan funding from the Michigan Legislature.
I agree the educational system is a mess. It's not just the system, a large portion the problem also lies with parents who expect teachers to be baby sitters as well.
