Kathleen Blake Yancey’s work has been “key” to many composition scholars’ research and teaching. The video focuses on three interpretations of the word “key”: as a change, as an important moment, and as an entryway. Each definition is connected back to Yancey’s work and the work of other scholars that has grown out of it. While each aspect is shown through the primary lenses of “Made Not Only in Words: Composition in a New Key” and Writing Across Contexts: Transfer, Composition, and Sites of Writing, several additional works by both Yancey and other composition scholars are connected to these central interpretations of “key.” Multimodality, Transfer, Reflection, and many other topics from these works and others are drawn into this conversation, and my own connection to these conversations is explored.
