One legal issue that identified in “Mothers Tongue”, was when Tan said ” but i have noticed in surveys in fact, just last week that — asian students, as a whole, always do significantly better on math achievement tests in English. And this makes me think that there are other Asian-American students whose English spoken in the home might also be described as “broken” or “limited”. And perhaps they also have teachers who are steering them away from writing and into math and science, which is what happened to me. And the legal issue is discrimination because of the kids being pushed to math and science instead of writing because of their “broken” English.
