In our traditional education, there are hegemonic speeches. One of these, work hard with the "scores", the memory, the repetition and the state's ideological reproduction. And that ideology is deeply interested in the market, the comparison between students, the measurement of IQ or any disorder. But the problem is behind that speech, people don't learn alone, people learn with a partner, with classmates, that could know more or less than they.
I think that this activities works when people study before, are nice indicators of knowledge in a specific moment, but this activities doesn't work for the measurement of the "learned". The big work is on speaking class, but also, people need to answer with their will or good disposal.
