Chen, Yi; Alejandra Behar, Patricia; Liu, Xiang; Chae, HuiSoo; Natriello, Gary

In this study, we introduced a general methodology, three parameter Poisson (3PP) model, for online video-driven discussion (VDD) engagement measurement. To make the model more robust and apply the model in small sample size case, we improved Duplicate, Erase and Replace (DupER) Augmentation in 3PP model. Finally, we conducted behavioral analyses to gain insights into patterns of students comment interaction on a video-driven discussion platform, Vialogues, in a real class environment.
