The present study tries to seek for what constructivists believe regarding curriculum development; they claim that learners construct their own reality or at least interpret it based upon their perceptions of experiences, so an individual's knowledge is a function of one's prior experiences, mental structures, and beliefs that are used to interpret objects and events. What someone knows is grounded in perception of the physical and social experiences which are comprehended by the mind . As language specialists, we should pay close attention to the point that the curriculum is the heart of education, the sharing of learning experiences between the teacher and learner. All else in the system should be derived from this: how learners should be assessed, how teachers should be trained and develop, what textbooks and other learning support materials should be like, how schools and the educational system should be organized and managed, and the allocation of resources necessary for the system to function.
