The characteristics of experimental pedagogy lie in using natural science experiments to study educational problems, emphasizing the simplification of research phenomena, strictly separating the tested methods, factors and conditions from other irrelevant factors, and observing the development and change characteristics of experimental objects in the educational process with the help of experimental instruments, special equipment and some artificial methods; It is emphasized that the reliability of experimental results is compared and quantitatively tested by statistical methods, so as to find the causal relationship between educational variables, and to reveal and establish educational principles accordingly. This makes the educational experiment change from the early experimental practice of teaching reform to the educational research based on this method with strict operational norms under the scientific paradigm.

Under the impetus of educational experiments, experimental methods are introduced into the field of educational research, which overcomes the inherent defects of speculation and illustration in previous educational theory research and forms the basic form of educational experiments that focus on quantification and exploration of reasons.
