The role that moderation plays in the effective functioning of online communities is relatively well studied in relation to both general free-time social media groups and discussion groups that are part of formal educational and professional learning initiatives. However, at the intersection of these domains, there are a growing number of large-scale informally-developed professional-learning groups. While this kind of group has been studied more generally, little attention has been paid to the particular moderation concerns at play in these hybrid online spaces. In this study, we examine moderation over a three-year period in a teacher-professional Facebook group with over 13,000 members. Maintaining an interpretivist stance while drawing on an exploratory statistical analysis of trace data to identify critical instances in the activity of the group, we adopt a Goffmanian approach to examine how moderation is performed. Based on this analysis, we find that moderation in the case group involved a particular balance of three different moderation concerns. In addition to the facilitation role that moderators are often described as having in groups associated with formal educational and professional learning initiatives, our findings show that moderation can also involve the monitoring of group norms more commonly associated with general free-time social media groups and the third moderation concern of acting as an expert member.

相对于作为常规教育和专业学习计划一部分的一般业余时间社交媒体组和讨论组，相对温和地研究了节制在在线社区有效运行中的作用。但是，在这些领域的交汇处，有越来越多的大型非正式开发的专业学习团体。尽管对这类小组进行了更广泛的研究，但对于这些混合在线空间中正在发挥作用的特殊适度问题却鲜有关注。在这项研究中，我们研究了教师专业的Facebook小组中超过13,000名成员在三年内的节制情况。在对痕迹数据进行探索性统计分析以识别小组活动中的关键实例时，在保持解释论立场的同时，我们采用了戈夫曼式方法来研究如何进行节制。基于此分析，我们发现案例组中的仲裁涉及三个不同仲裁问题的特定平衡。除了通常被描述为主持人在与正规教育和专业学习计划相关的团体中所起的促进作用外，我们的研究结果表明，主持人还可以包括更普遍地与一般的空闲时间社交媒体团体和团体相关的团体规范的监控。第三点是担任专家成员的适度考虑。我们发现，案例组中的审理涉及三个不同审理问题的特定平衡。除了通常被描述为主持人在与正规教育和专业学习计划相关的团体中所起的促进作用外，我们的研究结果表明，主持人还可以包括更普遍地与一般的空闲时间社交媒体团体和团体相关的团体规范的监控。第三点是担任专家成员的适度考虑。我们发现，案例组中的审理涉及三个不同审理问题的特定平衡。除了通常被描述为主持人在与正规教育和专业学习计划相关的团体中所起的促进作用外，我们的研究结果表明，主持人还可以包括更普遍地与一般的空闲时间社交媒体团体和团体相关的团体规范的监控。第三点是担任专家成员的适度考虑。
