IntroductionIt has been my pleasure to read and comment on the articles contained in this Special Issue of the Journal of Professional Capital and Community on the topic of Pracademia: Exploring the possibilities, power and politics of boundary-spanners straddling the worlds of practice and scholarship, guest edited by Trista Hollweck, Deborah Netolicky and Paul Campbell. When I was first asked to provide a rejoinder or afterwards for the Special Issue, I said yes as I have long been curious about the terms "pracademia" and "pracademic." I first heard the term pracademic in the early 2000s when I was working as a senior government official responsible for education research. At that time, pracademic was being used to refer to people with doctorates who were working in government (rather than academia), and the importance of valuing all roles involving connections between research, policy, and practice. Indeed, my own career has been centrally about connections and interactions between research, policy, and practice, including roles working in education systems to contribute to improvements in educational practice, as a government official and advisor informing education policies, and as a researcher and scholar seeking to contribute to the academic and education communities. Now, a couple of decades into the 21st century, Hollweck, Netolicky and Campbell argue there has been a surge-or resurgence-of interest in the concepts of "pracademia" and "pracademics" as understood and applied in the field of education. Hence, the impetus for this Special Issue contains six articles. I summarize these articles briefly below for readers who are reading this "Afterward" as a standalone article.The first article, Defining and exploring pracademia: identity, community, and engagement, is by the guest editors (Hollweck, Netolicky and Campbell). They provide a conceptual exploration of the term pracademic, including a review of relevant literatures in and beyond education, and then discussion of the definition and nature of pracademia specifically in education. They propose metaphors and key definitions and components to aid in understanding and investigating the concept of pracademics, plus draw on their own experiences as self-identified pracademics.The second article, Education focused pracademics on Twitter: building democratic fora, is also by two authors identifying as pracademics, Steven Kolber and Keith Heggart. The article is based on autoethnographic case studies of their own experiences, one as a practicing teacher and one as an early career researcher in a university, of engaging online to develop their professional learning, research engagement, and collaboration with a community of educators and researchers. Drawing on three examples of online activities-Twitter, TeachMeets and #edureading-they identify features of pracademic spaces in online fora to support networks of pracademics and contribute to the development of the education profession.The third article, Pracademic productive friction: boundary crossing and p...
