I struggle to predict counter arguments.
What counterargument would you make if you wanted to oppose the idea?
It seems like this is not an "arguable thesis." Do you know what that means? In order for a project to be meaningful it must argue a thesis that not everyone would agree with. Everyone agrees that ed reform is necessary, and if we see countries getting better student outcomes in math then we should learn from their example.
So... no one would argue against this. However, if you propose specific reforms, specific curriculum changes, then some people will argue against it. Some people will say, no, let's not use the techniques from Japan, but instead this new technique developed by Such and Such.
So... you need to focus on particular instructional strategies or policy changes... SPECIFICS. and then you will have people who disagree with you. And maybe they will prove to be right! So... get specific, and enjoy the discourse.
