A lack of evidence bridging the chasm between professional learning practices and commonly used, publicly available resources such as YouTube videos, remains a long-term challenge in both research and practice. The study introduced a YouTube video club for female early childhood teachers in Hong Kong (N = 29) to view, analyse and discuss STEM teaching videos. The participants wrote reflections and discussed with peers to exchange views on teaching content and strategies. All participants completed pre- and post-intervention surveys reporting their teaching beliefs, and five participants from the experimental group were invited for individual interviews. The questionnaire survey data were analysed using statistical analysis, while the interview data were analysed through inductive thematic analysis. The study, which was pre-post quasi-experimental, showed that the video club enhanced teachers' beliefs and attitudes towards professional practices in early childhood education. Qualitative analysis of teacher interviews revealed benefits and constraints of using YouTube videos for professional learning. The study transformed video clubs into a web-mediated mode using YouTube, Google Classroom and Zoom. The results have implications for the design and implementation of video clubs in teacher learning programmes. Copyright ©2023 Wiley.

By innovatively applying positioning theory with reference to a framework of willingness, capability and power, this study explored how pre-service teachers' professional identities dynamically change through the negotiation of various positions. A qualitative approach was adopted using data from six Hong Kong pre-service teachers in a teacher education programme for teaching Chinese as a second language. Multiple data sources, including interviews, reflective journals, classroom observations and lesson plans, were collected over one year. Pre-service teachers were found to negotiate individual deliberated self-positionings before entering the education programme and forced self-positionings from significant others during the education programme in three key stages: pre-positioning, negotiated positioning and performed positioning. Three differentiated positioning trajectories were identified that were greatly influenced by the pre-service teachers' levels of willingness, capability and power. Copyright ©2021 Routledge.
