movement or change he is responsible for and describe it
While Mann served in the Senate, the Massachusetts education system, with a history going back to 1647, was suffering, and the quality of education was deteriorating. Soon a vigorous reform movement arose, and in 1837 the state created he nation's first board of education, with Mann as its secretary.
With funds for the board's activities at a minimum, the position required more moral leadership than anything else, and Horace Mann proved himself up to the role. He started a biweekly journal, Common School Journal, in 1838 or teachers and lectured on education to all who would listen.
