Modern curriculum theory is predicated on the belief that the primary purpose of education is to change or modify the behavior of the learners. Curriculum, thus, consists of all the experiences the school provides to allow students to achieve the greatest possible fulfillment of their potentialities. Current curriculum improvement programs are attempting to come to grips with the reality of pupil differences in relation to knowledge. Such practices as team teaching, individualized instruction, alternative schools, career education, bilingual education and the back to basics movement have all precipitated curricular changes. In order to improve today's educational system we must involve the members of society who are directly responsible for the education of children in setting up a curriculum that is relevant to the learner and to the needs of the society of which he is a member.
