This paper focuses on understanding participation and interactivity patterns in asynchronous threaded online learning conversations (ATOLCs). We argue that traditional visual diagramming techniques used to analyze ATOLCs focus on structural information at the expense of temporal information, thus presenting an incomplete or misleading picture of participation and interactivity patterns. To address these weaknesses, we have generated a series of new visualizations for analyzing learners’ participation patterns in ATOLCs that include both structural and temporal information. In this work we describe the process by which we created our new visualizations, lay out the design trade-offs we faced and how we resolved them, and evaluate how the new visualizations facilitate the analysis of participation and interactivity patterns. We conclude with future directions for visualization of ATOLCs.
