Public education persuasive speech topics - physical exercise? Grades?

I am focusing on finding a persuasive speech topic but when I focus, I lose all thoughts at times.

:/

I am pretty comfortable with talking about public education and I have a few good topics but my professor is really closed-minded and really wants something 'perfect' as he says.

I am afraid to even ask him if it is good because last time I asked if persuading my audience that 'it should be required to graduate with a second language', was alright and he said no, it is rather informative.

So I am wondering if the below topics are acceptable as persuasive topics!

I am also knowledgeable in the fact the school system does not allow creative thinking but not sure how to persuade my audience anything around that.

Public education should not focus on grades

We should not go by age to go up to the next grade level

We should advance students to higher grades when we feel they are too smart for the grade level they are currently in

Should implement more career classes - rather than Math that we might not use

We should implement vocational schools more heavily with public schools (almost required -- but some don't want to tech careers)

Students should be pushed to get into a technical field

What are some good ones?
