The developmental life course perspective (DLC) focuses attention on the socio-historical context in which we live our lives as it influences opportunities and life events that produce cumulative advantage or disadvantage. These large contextual forces shape preference and behavior, and it is within this context that the individual exerts personal agency. This perspective has particular utility as a conceptual framework for human behavior and the social environment courses as it integrates individual-level behavior within a social forces context. This article describes the DLC and its application as both a conceptual and an organizing framework for human behavior and the social environment courses at the masters level. It is illustrated with a case example.
