Why do Asian consistently outperform American children on international assessments in math and science?

Answer 1

Because Math and Science require a basic comprehension of the language of your native country, which you do not have. "Asian" and "American" should both be capitalized, and "Why do Asian consistently..." is a fragment. Asian WHAT outperform American children? Asian Cars outperform American children? Asian food outperforms American children? To answer your question, it is because they realize they must comprehend to learn, whereas American children merely memorize with no true understanding just long enough to regurgitate information for a test, and subsequently forget it promptly.
