The document discusses the importance of student adjustment in school and the teacher's role in facilitating this process. It states that most learning occurs in a social context, so teachers should aim to improve the social environment of the school. Specifically, teachers should develop a democratic attitude and organize the social environment of the class to make each student feel included. Additionally, the curriculum, facilities, classroom climate, and relationships between staff can all positively influence a student's adjustment. Evaluation methods also impact mental health and should avoid numerical marking or labels like "failing".
