To what extent does political bias impact the good quality of education?

Issue by Wilson: To what extent does political bias influence the high quality of education and learning?
I am engaged to hear about your reactions to this query, which has been partly motivated by the current Yahoo! post “Texas ed board vote displays far-appropriate influences”: http://news.yahoo.com/s/ap/us_texas_schools_social_scientific studies

Do you assume that the introduction of political biases into textbooks, regardless of whether still left or right, impacts the good quality of one’s training? If so, to what extent?

Thank you quite significantly for your time!
