The learning sciences emerged in the early 1990s as an interdisciplinary field that draws on multiple theoretical perspectives and research paradigms. Researchers in the learning sciences attempt to understand the nature and conditions of learning, cognition, development, and related areas of human performance in material, social, and cultural contexts by conducting both laboratory-based and naturalistic investigations. The intent of learning sciences research is to develop research-based claims about how people learn that have practical, pedagogical, and theoretical implications.
