Dilemmas in professional code-switching for teacher educators in higher education
本文研究了第二职业学者（实践学者）在专业与学术领域间转换时面临的语码转换困境，提出了专业过渡模型，帮助大学支持这类学者发展学术身份。
This article interrogates the professional socialisation work faced by second-career academics (‘pracademics’), who choose to straddle professional and academic spheres. We offer that the identity formation and re-formation pracademics undergo as part of this multi-socialisation process constitutes a dilemmatic space, underscored by competing values, alternatives, and priorities. Specifically, pracademics experience conflict in the dilemma of holding knowledge and identity as an expert within their professional context, with that of being a novice within the academic context. As such, individuals transitioning from or between professional and academic spheres must both acknowledge the need for and engage in the work of ‘code-switching’ to successfully develop distinctive knowledge and identity as an academic whilst maintaining productive connections with their first career.To conceptualise our investigation, we present two stages of analytic reflection. The first, an examination of the conceptual relationships formed at the intersection of three theoretical fields: professional identity, pedagogical content knowledge (PCK), and code-switching. The second draws these relationships together into a Model of Professional Transition that examines how all three fields contribute to pracademics effectively transitioning into and between professional and academic roles. Examples of second-career education academics illustrate these relationships, as there is an added layer of complexity in deconstructing the impact of PCK in prior-to-university contexts on PCK in higher education. As such, we propose that pedagogical content knowledge should be re-imagined as ‘andragogic content knowledge’. The Model for Professional Transition may assist universities in supporting second-career academics with the important work of code-switching between professional identities.
