In my last blog post and presentation I referenced a study, Understanding user behavior in large-scale video-on-demand systems,  by Yu et al. I thought this study had some interesting analyses which could be applied to data from Vialogues. In particular I wanted to look at the relationship between the popularity of a Vialogue measured by the number of page visits and the session lengths or how long people spend on the Vialogue page.Below is the distribution of Vialogue video lengths.
Here are the slides for our presentation!This past month the research team has been working on analyzing the usage and behavior on some of our EdLab Platforms. This work will be presented during this Tuesday’s (8/29) Development and Research Meeting. We will be considering the pur...

My current project is to analyze discussions on Vialogues. There are several directions that the research project could lead. I’m coding the conversations with a focus on fundamental theoretical frameworks.There are multiple coding systems in previous research studies that serves different purposes from various perspectives. I would like to observe the knowledge construction process in collaborative learning through the developmental psychological perspective. In social constructivism, there is the knowledge constructed t...
As we continue to mine data to help us better understand Edlab educational apps, library services, and users/learners/patrons, it is helpful to have a conceptual understanding about various kinds of analytics and their strengths for design and decision making. I ran into this presentation “
