Here is my proposal for solving this.
1. You teach Math
2. You teach Science
3. You teach English
4. You teach a foreign language
5. You teach American history, state history, world history
6. You teach physical fitness
7. You teach music
8. You teach critical thinking
There is no opinion, no indoctrination and no school board intervention on curriculum. The PTA is the sole arbiter. Any deviation is automatic dismissal from the job. Finally, every teacher gets an automatic 25% increase in salary to be used to fund their own insurance policies and retirement accounts. The district can match the contribution just like the private sector. Teachers performance will be used for raises, probation and release from position.
You must think teachers can be deprogrammed from their indoctrination. The solution should be every teacher with an Ed degree is fired and replaced by someone that actually has an education. The system needs to be disrupted. The real problem resides at teachers colleges. When demand dries up for Ed degrees you will have far fewer indoctrinated teachers. Another step is to bust teacher unions. Teachers need to be paid based on performance and fired for a lack of performance. Lastly, education tax dollars need to go directly to parents. Parents can then use that money on any form of education they desire, including homeschooling.
