The Publisher regrets that this article is an accidental duplication of an article that has already been published in US-China Education Review, Volume 3, Number 1 (2013) 51-58, http://www.davidpublishing.com/show.html?10324 (as this article does not have a DOI number we are providing the link to access the paper). The duplicate article has therefore been withdrawn
