A longitudinal multiple case study was adopted to examine how three key transformative learning elements—disorienting dilemma, critical reflection, and rational dialogue—occurred in an executive coaching engagement and the learning outcomes that emerged. A key finding was that, in addition to the three accepted elements, there is a fourth element (acceptance) that precedes the rational dialogue.

Stakeholders: The study will benefit scholars and practitioners in the fields of human resource development, executive coaching and leadership development. Click here to read full article
