The purpose of this research was to examine whether there are resultant behavioral changes in professionalism for returning adult RN–to–BSN students and to identify teaching-learning activities that stimulate transformative learning. Mezirow’s adult learning theory served as a theoretical guide for the study. A convenience sample of students enrolled in a RN-to-BSN completion program during 2 academic years was surveyed using the core standards from the American Association of Colleges of Nursing’s essentials of baccalaureate nursing education. A total of 26 learning activities were identified as creating cognitive dissonance (conflict of values). Changes in professional behavior 3 months postgraduation included increased collaboration with the health care team, increased patient advocacy, and increased confidence in the role as a teacher of patients and families. The findings indicate that planning learning activities in nursing curricula can foster perspective transformation in professionalism.
