M. F. Cleugh 
Discipline and Morale in School and College [PDF ebook] 
A Study of Group Feeling

Originally published in 1971, the author was concerned with a nexus of related ideas: group spirit, morale, discipline, discrimination, stigma. How, she asks, are these connected with leadership, both that of the assigned person in authority, lecturer or teacher, and that of the dominant spirits within the group? What is their relation to backwardness, and the place of the slow learner in the school morale system? Answering these and other questions, particularly around morale, the first part of the book contains a number of case studies and examples of varying degrees of complexity. These are intended to act as pointers or guides for the discussion of problems, which takes up the second half of the book.
