Conceptual change
Conceptual change is the process whereby concepts and relationships between them change over the course of an individual person’s lifetime or over the course of history. Research in three different fields – cognitive developmental psychology, science education, and history and philosophy of science - has sought to understand this process. Indeed, the convergence of these three fields, in their effort to understand how concepts change in content and organization, has led to the emergence of an interdisciplinary sub-field in its own right. This sub-field is referred to as “conceptual change” research.
