Education is an academic discipline that seeks to establish a general theoretical system to explain educational phenomena by studying highly complex educational phenomena through various academic approaches.
This type of pedagogy has normative scientific characteristics in that it systematizes the research results on what kind of values ​​we should have as human beings.
Moreover, it also has the characteristics of practical ethics or applied science in that it systematizes empirical research on how to effectively educate people about values ​​worth dedicating themselves to.
Educational psychology is a subfield of education that studies the concepts, laws, theories, and effective practices of the teaching-learning process, that is, the educational process, to effectively achieve educational goals.
In other words, educational psychology is a discipline about educational practice and for educational practice.

If educational philosophy is a field of education that synthesizes a knowledge system related to 'why' we should teach and learn, and curriculum is a field of education that synthesizes a knowledge system related to 'what' we should teach and learn, then educational psychology can be said to be an academic discipline that synthesizes a knowledge system related to 'how' we can teach and learn well.
