The university and students’ movement has been one of crucial elements of the sociopolitical developments in iran history; they are also the most significant to identify active sociopolitical conflicts, gaps and controversies in Iran at present. Within the framework of a sociological approach and emphasizing on a ''structuralist'' perspective theorizing the social movements, the author intends to reveal the gap between government and university in the country during 1979-2006 that led to a developed students’ movement. The author’ principal aim is to specify contribution, influential effects, structural role an function of the government of Islamic Republic in emergence and deepening of such gap, its formal, political structure and examining transactional process, criticism, reform, confrontation and the gap between the government and the university, and discussing the government’ s role and contribution during the 4-year cultural revolution, Iraq-Iran war, reconstruction and reforms periods. Finally, the author conclude that a ''political radicalism'' of the students’ movement, in especially during the Reforms time, has been the product of the structural-functional paradox of the traditional government and the modern academics institutions.
