Is "representation" here "representative" or "symbo"l or something? What does it exactly mean?
ex)In the Mao era of China, students displayed their peasant backgrounds with pride and elite universities were full of rural students. But these days, while peasants make up 58 percent of China's college-age population and 50 percent of university students, they are concentrated in vocational schools and less prestigious universities. One big reason for this representation gap is that the university-application process has been shifting......
I haven't come across this phrase before, though I can work out what it means from the context.
Represent means to stand for or symbolise. Representation means the act of symbolising/portraying something.
In your passage, it is the rural/peasant population at universities being discussed. The passage means that while 50% of university students come from a rural background, they are concentrated in vocational schools and less prestigious universities. In other words, if China had a truely representative educational system, the prestigious universities would have a student population that mirrored the wider population eg. 50% would come from rural backgrounds - since this isn't the situation, there is a 'representation gap'.
Hopefully a teacher or someone can try and explain it a bit better.
