"Education is crucial in any type of society for the preservation of the lives of its members and the maintenance of the social structure. Under certain circumstances, education also promotes social change. The greater portion of that education is informal, being acquired by the young from the example and behavior of elders in the society. Under normal circumstances, education grows out of the environment; the learning process being directly related to the pattern of work in the society. [...] Indeed, the most crucial aspect of pre-colonial African education was its relevance to Africans, in sharp contrast with what was later introduced. The following features of indigenous African education can be considered outstanding: its close links with social life, both in a material and spiritual sense; its collective nature; its many-sidedness; and its progressive development in conformity with the successive stages of physical, emotional, and mental development of the child. There was no separation of education and productive activity or any division between manual and intellectual education. Altogether, through mainly informal means, pre-colonial African education matched the realities of pre-colonial African society and produced well-rounded personalities to fit into that society."
