Abstract

This study investigates how the format of asynchronous online class discussions (whole class vs. small group) affects the structure and content of student interactions. Data were collected from 8 weeks of discussion forums in a graduate-level, asynchronous, online course at a comprehensive university in the southeastern United States. Social network analysis (SNA) metrics, such as response rate, reciprocity, transitivity, diameter, density, in-degree, and closeness centrality, were used to evaluate interaction structure. Linguistic Inquiry and Word Count (LIWC) software was used to analyze the linguistic features of the interaction content. Findings revealed differences between the formats: whole-class discussions exhibited greater diameter and variability in response rate, emphasizing formal and analytical communication. In contrast, small-group discussions displayed higher reciprocity and transitivity, as well as more support and socioemotional engagement. Findings underscore the importance of designing and facilitating collaborative online learning experiences by strategically employing discussion formats to meet specific learning objectives. Implications for practice include incorporating both whole-class and small-group discussions to leverage the strengths of each format, such as creativity and critical thinking in larger groups and mutuality and support in small groups. Future research should examine these effects across different educational levels and subject areas, considering instructional contexts and personal learner characteristics.
