"Human Agency at Work" by Dr. Michael Goller offers a comprehensive analysis of the role of human agency in the context of professional training and development. The author presents a structured theoretical framework that views human agency both as an individual disposition and as a series of self-initiated, goal-directed behaviors. These behaviors are crucial for the learning and development processes of employees, particularly in the field of elder care. Through the conduct of three empirical studies, the relevance of human agency for the development of professional expertise among caregivers in geriatrics is thoroughly examined. The work was awarded the Dissertation of the Year Award by the American Educational Research Association (AERA) Workplace Learning SIG in 2017, highlighting the significance and impact of the research.
