This article presents the interpretation of the bioecological model of the American psychologist Urie Bronfenbrenner, applied to the growth process, especially during the school period. It should be noted that any psychoeducational intervention is designed to change both in the person and in the surrounding environment with which the person is in constant exchange. An important role in the process of change is played by a significant adult figure, which is often a parent, teacher, educator. Given that this process is taking place in modern society, which is subject to constant changes, it seems important to recall some basic dynamics that lead to healthy individual and social growth.
