"But this would be a good research topic. How many people dislike math lessons in general versus how many dislike a particular teacher or style, and how many of the later went on to excel in math anyways."
PISA already did that for us. Even in the lowly USA, if you define "hate math" as the percent who strongly disagree with the statement "I do math because I enjoy it", only 22% hate math.
What might be more productive is to look at the countries where most students AGREE with that statement:
55% Hong Kong, Lichtenstein, Romania 52% Switzerland, Greece, Turkey, China (Shanghai) 47% Iceland, France 40% Taipei, Macao (China), Russia 38% Australia, Canada, Germany, Estonia, Canada, UK 30% Czech Republic, Belgium 23% Austria
Do so many students in these high performing countries enjoy math because of the way their teachers teach it, or is it an innate ability which causes them to enjoy math?
