• interactions with others and the environment are key to development,
• we all experience more than one type of environment, including
• the microsystem - such as a family, classroom, etc is the immediate environment in which a person is operating,
• the mesosystem - which is two microsystems interacting, such as the connection between a child’s home and school,
• the exosystem - which is an environment in which an individual is not involved, which is external to his or her experience, but nonetheless affects him or her anyway. An example of an exosystem is the child’s parent’s workplace. Although a child may never have any role in the parent’s workplace, or, in fact, never even go there, the events which occur at the child’s place of employment do affect the child. For example, if the parent has a bad day at work, or is laid off, or promoted, or has to work overtime, all of these events impact the child, and finally,
• the macrosystem - or the larger cultural context.
Each of these systems are characterized by roles, norms (expected behavior) and relationships. For example, an individual usually acts differently within his or her own family than within a classroom. The person may speak more often at home, be less goal-oriented, and, almost certainly, will not sit at a desk for hours on end. Other things being equal , according to Bronfenbrenner, when the relation between different microsystems is a compatible one, development progresses more smoothly. A common example of this is the relationship between home and school. When role expectations are similar in both settings, e.g., try your hardest, do your own work, be on time, etc., children will be expected to perform
