Question 3. Ignore the text books. Buy copy machines and use them to print out lessons that are meaningful, not political indoctrination. Maybe the state can make a school district buy books. They can't make a school teach from them.
Question 4. Repetition, repetition, repetition.
Question 5. See reply to number 3.
In general, it is way past time for local schools to tell the Federal and State education parasites to shove it. Teaching children to read & write and to add, subtract, multiply and divide does not take a bureaucracy filled with PhDs and that message needs to be delivered through defiance. Let it go to court and see who wins --- the school that suceeds or the breaucrats who attempt to prevent them from suceeding.
Not saying your solutions would not work... However, how do you propose to “sell” the increased costs to the taxpayers?
