The behavior training for school beginners is a professional book designed as a practice-oriented group program to promote the social and emotional skills of children at the start of school. It provides educational professionals with a comprehensive training manual that explains the theoretical background of behavior management and offers practical guidance for dealing with challenging behavior.
