Understanding teachers' online professional learning: A "community of inquiry" perspective on the role of Chinese middle school teachers' sense of self-efficacy, and online learning achievement.

Teachers' online professional development (PD) has been valued as a crucial and effective way to promote teaching competencies. Forming a professional learning community has been recognized as a means to promote effective PD. Within this realm of research, the Community of Inquiry (CoI) framework was deemed as a collaborative-constructivist process model that describes successful online learning experiences. The CoI has been associated with many psychological and educational variables, such as learning achievement and self-efficacy. This study leveraged on the CoI framework to assess teachers' online professional learning quality and explored its relationship with their self-efficacy and online professional learning achievement. A total of 456 teacher participants from Chinese middle schools participated in our study. A suite of questionnaires (the Community of Inquiry Questionnaire, the Teacher Efficacy Scale, and the Perceived Online Learning Achievement Scale) was distributed. Linear regression, PROCESS Macro mediation, and moderation analyses were run on the data to answer the research questions. Results revealed a significant relationship between teachers' online learning quality and their self-efficacy and learning achievement. The mediating roles of self-efficacy and learning achievement were confirmed. The moderating role of time spent on receiving online professional learning was also recognized. Implications and future directions were discussed.
