This study investigated the role of experienced practitioners in promoting pre-service teachers' knowledge construction and social interaction in an online professional learning community.,A repeated measures design with control and experimental groups was adopted. Two practitioners supported pre-service teachers in the experimental group to discuss issues around teaching practice. Social network analysis (SNA) and content analysis (CA) were used in the analytical approach.,CA revealed that the practitioners increased pre-service teachers' levels of knowledge construction and high-cognitive discourse. SNA showed that the practitioners enhanced pre-service teachers' professional ties. Though collaboration in high-level knowledge building occurred predominantly in peers in the same discipline, the presence of the practitioners facilitated the development of more cross-disciplinary ties in the experimental group.,The practitioners can be considered as a pedagogical tool to enhance pre-service teachers' engagement in the process of professional learning. This study suggests that in order to enhance the collaboration among pre-service teachers from different departments, the online activity should be designed to enhance interdisciplinary collaboration.,The study contributes new knowledge about the ways in which practitioners can enhance the collaboration among pre-service teachers in an online PLC. It also provides insight on how to combine CA and SNA, to examine professional learning.

促进职前教师参与在线专业学习社区

本研究调查了经验丰富的从业者在在线专业学习社区中促进职前教师的知识建设和社交互动中的作用。采用了具有控制和实验小组的重复措施设计。两名从业人员支持实验小组中的岗前教师讨论有关教学实践的问题。分析方法中使用了社交网络分析（SNA）和内容分析（CA）。CA显示，从业人员提高了岗前教师的知识建构和高认知话语水平。SNA显示，从业人员加强了职前教师的专业联系。尽管在高层次知识建设中的协作主要发生在同一学科的同行中，从业者的到来促进了实验组中更多跨学科关系的发展。从业者可以被视为一种教学工具，可以提高职前教师在专业学习过程中的参与度。这项研究表明，为了增强不同部门的职前教师之间的协作，应该设计在线活动以加强跨学科的协作。该研究为从业者如何增强职前教师之间的协作提供了新知识。在线PLC中的教师。它还提供有关如何将CA和SNA结合起来以检查专业学习的见解。从业人员可以被视为一种教学工具，可以提高职前教师在专业学习过程中的参与度。这项研究表明，为了增强不同部门的职前教师之间的协作，应该设计在线活动以加强跨学科的协作。该研究为从业者如何增强职前教师之间的协作提供了新知识。在线PLC中的教师。它还提供有关如何将CA和SNA结合起来以检查专业学习的见解。从业人员可以被视为一种教学工具，可以提高职前教师在专业学习过程中的参与度。这项研究表明，为了增强不同部门的职前教师之间的协作，应该设计在线活动以加强跨学科的协作。该研究为从业者如何增强职前教师之间的协作提供了新知识。在线PLC中的教师。它还提供有关如何将CA和SNA结合起来以检查专业学习的见解。这项研究提供了有关从业人员如何增强在线PLC中的职前教师之间协作的新知识。它还提供有关如何将CA和SNA结合起来以检查专业学习的见解。这项研究提供了有关从业人员如何增强在线PLC中的职前教师之间协作的新知识。它还提供有关如何将CA和SNA结合起来以检查专业学习的见解。
