Three studies using the Dreyfus model of skill acquisition were conducted over a period of 21 years. Nurses with a range of experience and reported skill-fulness were interviewed. Each study used nurses’ narrative accounts of actual clinical situations. A subsample of participants were observed and interviewed at work. These studies extend the understanding of the Dreyfus model to complex, underdetermined, and fast-paced practices. The skill of involvement and the development of moral agency are linked with the development of expertise, and (...) change as the practitioner becomes more skillful. Nurses who had some difficulty with understanding the ends of practice and difficulty with their skills of interpersonal and problem engagement did not progress to the level of expertise. Taken together, these studies demonstrate the usefulness of the Dreyfus model for understanding the learning needs and styles of learning at different levels of skill acquisition. (shrink)
