Schooling the World has just announced that their film is available this month for free preview. Schooling the World: The White Man’s Last Burden is now streamed with subtitles in eleven languages. Its free downloadable discussion guide has abundant material that is fairly easily re-framed to make it explicitly relevant to TOK.
I recommend this film highly as background for Indigenous Knowledge. It prompts some giant knowledge questions about shared knowledge in different cultures — what knowledge is considered most important, how it is learned and validated, and how it is shared from generation to generation. This is a thought-provoking film, beautiful to watch.
