In terms of culture....
I think that only educating a person about their own cultural preferences can be a very dangerous thing. Without teaching others about different cultures and ways of life, we would become a very narrow-minded culture, and in theory, we would be reversing the past 50 years or so of 'multi-cultural' work that we are trying to bring into our society- teaching foreign languages, discouraging racism etc. Without teaching people about these different cultures, we would be regressing to a racist, narrow-minded time that we should (and have!) left behind us!
Especially with today's digital advances, we are more and more able to talk to people from other countries, and learn things from them. I can't see that this is anything but a positive thing! He are broadening our horizons and have the opportunity to learn about all the different cultures of the world. As professor Puncky Heppner suggests “We are all living in cultures with different norms. Culture affects human behavior. The more we learn about other cultures, the better teachers, mentors, scholars and therapists we can be. Ultimately, understanding different cultures makes us better people.” (Jackson n/a)
In terms of person preference....
I can understand slightly more why there could be advantages. For example, those children who are in need of extra help (dyslexia etc). Surely that counts as a personal preference? In which case by all means, they should be receiving a different education to that of other children...not in terms of what they learn, but in terms of how they learn it. I think that is the most important point here. All children should learn the same, the only thing that should be altered to help them, is the way in which different children learn it!
This has been recognised at some schools: 'The Comenian Programme has been developed to support our academically most able and creatively-talented pupils. We help individuals realise their full potential by nurturing their aspirations and guiding motivation.' (fulneckschool.co.uk), and with help like this being offered, these sorts of 'tailored needs' I think can be beneficial!
