In the history of educational research, theory and practice have not found their interrelationships easily. The two basic contexts of education are often seen as out of touch with each other and as somehow distinctive fields of interest. Rhetorically their respective standpoints are often taken to be irreconcilable in that theory is considered as more or less always out of concrete grasp and practice as necessarily theoretically uninformed. Theory has its perspectives and practice its own. The tension between the concepts of theory and practice has a long history. The important of this paper comes from The necessity of educational research in the quality of educational system , the gap between theory and practice in educational research in Egypt ,it is difficult to divide researchers (those comfortable with theory and those less so), within educational research. In this paper, I study the necessity of theory, and discuss its role in practice and in framing research questions, informing analysis, and promoting reflexivity on the significance and relevance of research. I illustrate this process by discussing the ways theory can assist in the generation of research agendas and questions. I will consider different paradigms of educational research in terms of how they handle the relationship between theory and practice. Specifically I will refer to theory and research within the broad field of teaching. I take as a point of departure that substantial gains could be made if theory and practice could be more fruitfully connected in educational theory.

I will use in this paper the descriptive method and electronic Delphi panels to identify the complementary and conflict between theory and practice. The sample of this paper will be experts and professors in the field of educational research from Egypt and some developed countries.

The expected results of this paper are explanation the relation between theory and practice. In addition, there relation with the production of knowledge and the practice of education with its reproduction, How practitioners produce knowledge in the empirical studies of research to be understood? .Theoretical and empirical studies represent two relatively autonomous roads to Knowledge, their interrelationship is essential to scientific method, and educational methodology needs to integrate these aspects from the standpoints of both theory and practice.
