Research is an important aspect of academic disciplines. In this paper Curriculum Research (CR) has been discussed in several sectors. After an introduction, attempts have been made to mention past and present efforts and scientific literature on the basis of historical trend. Then, from the perspective of four active traditions in CR and based on the experts in each tradition, CR are discussed. In the tradition of recognizing framework and defining the variables of CR, views of Johnson, Kimpston, Rogers and Posner; in the tradition of empirical research in curriculum, Walker views and in the tradition of perspectives or paradigms of CR, views of Schubert, Haggerson, Connelly, Clandinin, Aoki and Reid are discussed. Finally in the tradition of forms or methods of CR, Edmund Short academic works and perspectives are discussed and development of his ideas have been proposed. In the last section, referring to the emergence of new perspectives in curriculum research, presented topics are summarized.
