This study discusses the problem of Bedouin girls dropping out from the public school system in the Negev region of Israel. Data show that this phenomenon results from a conflict between the modern Israeli institutes' perception of modernity (which promote coeducation) and the Bedouin traditions that remain the cultural ethos of the girls' fathers. Israeli institutions' perception of modernity (enlightenment theory) aims to modernize the Bedouins according to Israel's modern principles, thus revoking traditional Bedouin values (sex separation). This paper promotes a post-modern theory that calls for embedding feminine traditional values of local communities as a necessary process in the development of modernity.
