The Development of Expertise: The Journey From Acclimation to Proficiency

The Model of Domain Learning (MDL) is an alternative perspective on expertise that arose from studies of student learning in academic domains, such as reading, history, physics, and biology. A comparison of the MDL and traditional models of expertise is made. The key components and stages of the MDL are then overviewed. Discussion concludes with a consideration of evidence-based implications of this model for educational practice.
