After having read the article and gathering some of my notes I was taking I can conclude that Kumashiro views common sense as a sort of normal condition or status quo way of thinking in the context of education. With his American upbringing his notion of education is seen as oppressive to less privileged and marginalized peoples and he strives for students, teachers and staff to challenge the existing methods of teaching in America (the west) as the ‘best’ or ‘superior’ way. Common sense to someone can be a misplaced set of rules that have just always persisted. He then lays a foundation to stress the importance of teaching in an anti-oppressive manner which breaks apart the common sense surrounding education systems.
Common sense is then important to pay attention to because of possible inherent prescriptions or values that would otherwise be deemed oppressive to a set of people or demographics. His trip to Nepal is an example of his ideas of education being superior to the Nepali education system. He was wanting to use his own cultures education system because to him it was common sense and the way it ‘should’ be and therefore pushed onto others not used to it. Advocating an alternative approach through the means of anti-oppression is the core means by which he wants teachers to instruct and attempt the resist the notion that anything is ‘common sense’.
