However, when the comparative approach is applied in education it may be defined as being a combination of pedagogy and the social sciences. The comparative approach in education deals with the structure and purpose a school serves. It is suggested by Noah and Eckstein (1969) that the field of education and the social sciences have merged because researches have focused on analogous types of statistics and congruent subject matters. Furthermore, the other reason for this merger between fields is the noticeable interest in quantitative and experiential and approaches of investigation (Noah and Eckstein 1969). The application of the comparative approach in education is purposeful for four main reasons. Crossley and Watson (2004) have tried to identify these purposes. Firstly, it allows stakeholders to comprehend their own educational structure. Secondly, it provides individuals with the opportunity to also be able to comprehend other people's educational structures, their cultures and its societal interactions. Thirdly, individuals would be able to recognise contrast educational structures, procedures and effects as a means of recording and comprehending the issues in education, and assistance to the development of educational guiding principles and traditions. Fourthly and finally it supports enhanced global comprehending and collaboration owing to augmented understanding to various beliefs and traditions of the world.
