北京师范大学 教育研究方法讲座系列 Lecture 3 The Design and Logics of Comparative-Historical Method in the Social Sciences
The essentials of comparative studies We have only one means of demonstrating that one phenomenon is the cause of another: it is to compare case to cases where they are simultaneously present or absent. When the phenomenoncan be artificially produced by the observer, the method is experimentation in its proper sense. When, on the contrary, the product of fact is out of reach, when we can thus only bring them together as they are spontaneously produced, the method we use is that of indirect experimentation, or comparative method. (Durkhiem, Quoted in Dogan and Pela,1990,P.15-16)

The essentials of comparative studies "Comparison is a universal method in the social sciences; it is worthwhile not only to those who study in international field... t is not surprise that the historical method is so often combined with comparative method. Dogan and pelassy, 1990, P 16 "Comparative sociology is not a special branch of sociology, it is sociology itself, in so far as it cease to be purely descriptive and aspires to account for fact. (urkhiem, P. 157; Quoted in Schriewer, 2003, P 5)

The Basic Principles of research design of comparative research Morris Zelditch(197)) specifies that the design of comparative research is conditioned largely by four rules Comparability: Two or more instances of a phenomenon may be compared if and only if there exists some variable, say V, common to each instance J.S. Mill's 1st Canon Method of agreement: No second variable, say U, is the cause or effect of v, if it is not found when v is found. J.S. Mill's 2nd Canon(Method of Difference No second variables v is the cause or effect ofy if it is found when v is not

The Basic Principles of research design of comparative research Morris zelditch(1971) specifies that the design of comparative research is conditioned largely by four rules Rule of one variable: No second variable u is definitely the cause or effect of v if there exists a third variable, w, that is present or absent in the same circumstances as U. In order to verify that U and v are correlated in the design where there are other 2 variables, say w and x, we need at least eight cases(2x2 a x2 )of the following nature
