Using an open systems model (the formal organization, the informal organization, the environment, and change through feedback from the environment) to include the many topics of the sociology of education, this book demonstrates several theoretical approaches and their practical applications to current educational issues, and the structure and processes that make education systems work.
The sociology of education by Jeanne Ballentine is a very good introduction to the subject, easy to read and diverse enough, I would say. It presents the different fields involved into the study, with the open systems model, having chapters on the organisational structure, on the influences from society, the life of students and teachers, the impact of race, gender or class, the challenges and the drivers of change.
