After more than 100 years of successfully practicing a traditional model of student teaching, a midwestern university recently transitioned to a new co-teaching model of student teaching. What factors contributed to the decision to implement a co-teaching model? What process was used to guide, facilitate, and implement this major change in the way things had always been done at this university? What partnerships were formed during the implementation process? The authors share the steps taken to implement this shift in paradigm and how the co-teaching model continues to evolve.
