As someone who is not in the field but knows some teachers personally:

1. Increase/ even out pay. Meaning fix pay scales in underfunded schools and re evaluate 'overfunded' school pay.
2. Going hand in hand with pay; create a teacher fund for classroom supplies. My son's teacher pays for her students in class crafts (2nd grade) and we live in a respectable tax bracket district.
3. To combat the 'throw money at it' belief that can creep into education, use evidence-based approaches to addressing educational shortcomings. Make sure they are tailored to the community and student body.
4. Don't allow politics to dictate policy. There is an unfortunate grassroots attempt to restrict education based on religious belief or hyped up fake news. This is spilling over into parents acting like children at board meetings, shouting, and some trying to 'infiltrate' boards in order to enact restrictive and damaging policies. Please stop. No person looking at the teaching profession wants to see this sort of crap spill over into their classroom eventually.
5. Hire actual teachers to lead the department of education, and make sure those in leadership roles actually understand the battles teachers at all levels face.

I am sure actual teachers will be able to speak more to this than I will, but this is some of the stuff I've seen friends in the profession rail against. There is no black and white approach to education.
