Relationship between social psychology and educational psychology For some time I have been trying to figure out what the connection between social psychology and educational psychology is. By their definition, it seems that there at least one (major) point of connection. Both disciplines have the term "psychology" in their title. 

However, if you go further to investigate the connection, you might find that Wikipedia entry on educational psychology seems a bit confusing:

"Educational psychology is the study of how humans learn in educational settings, the effectiveness of educational interventions, the psychology of teaching, and the **social psychology of schools as organizations."

Does it mean that social psychology should be considered as a part/subdiscipline of educational psychology?
No, social psychology is not a subfield of educational psychology. Social psychology is one of the basic disciplines of psychology (like e.g. personality psychology or developmental psychology), whereas educational psychology is an applied discipline (like e.g. clinical psychology or industrial/organizational psychology). A sort of standard definition of social psychology is, that it is the 


  the study of the manner in which the personality, attitudes, motivations, and behavior of the individual influence and are influenced by social groups. (Merriam-Webster, 2013)


This means that as soon as there is some sort of social interaction involved in an educational setting, both disciplines are concerned.
