1) Teachers should be paid more.
2) Teachers shouldn't be pressured to work so many hours off the clock (after school).
3) Teachers may continue to make their own lesson plans, but they should always have available lesson plans available to them.
4) School administrations should protect teachers from harassing parents.
5) The number of administrative employees & administrations in general should be reduced or consolidated. You have some school districts with over 100 schools, and others shepherding just a few. The differences between districts can be very big (especially when it comes to lesson plans).
6) Politics is f-cking us hard here. Education should be easy to fund and a non-issue. The current situation is under-serving our children, and will create a feedback loop of underfunded/undervalued education. I personally believe a lot of allocated funds are spent wastefully on the administration and not teachers.
7) I wish we had online examinations that students could take over and over from day #1 of the school year to improve on over the year. There could be material that requires teachers be present to administer, and others that students can do on their own at home (and possibly cheat on). It would have helped me immensely to be familiar with what we were going to learn about "next month". I first encountered a syllabus with a month-to-month plan in community college.
8) Can't forget this: F-ck zero tolerance policies. Schools need a lawyer on-site looking out for the rights of students.
9) You shouldn't need a masters degree to teach 5th grade algebra. It should be easy to hire someone off the street who can pass a background check and exams against the course they might teach.
10) And then easier ways to account for students so it doesn't take 15 minutes to 'start class'. Longer days that start later (8am) & less/no homework.
