I saw the question Research on how to teach math to children - what proven approaches are there to teaching math effectively?. I think that question could be really useful and may be worthy of drawing the attention of so many Mathematics Educators Stack Exchange users to. Then researchers will be able to use the answer to find other researchers who are already researching how to fix up the education system and collaborate with them. I think there are a lot of flaws in most education systems in the world. I think a lot of schools are trying to teach very advanced stuff in an unclear way and students are struggling to figure out what they're trying to teach them.
