In this way, teachers can preserve culture and even improve and enrich children's lives by keeping them in touch with their cultural background and guiding them into the 21st century with teachings and knowledge all performed in their native language. This method allows the Ojibwe culture to survive and not encourage its extinction if the members of the tribe were to somehow completely assimilate into American culture.
