Title: Visualizing Course-Taking Patterns via Sankey Diagram
Author(s): Xiaoyue Cheng*

Keywords: Course-taking pattern; Sankey diagram; data visualization

The course-taking data of high school or college students has become an important support to education providers and policymakers, as it describes student learning pathways and barriers on a large scale. It can also be used to compare behaviors from different groups of students, improve the curriculum design and enrollment prediction. However, visualizing course-taking data is not a easy task because of the challenges from three components: students, courses, and time. How to summarize a group of paths taken by different students? How to align the nodes of courses by time? How to clean the time variable when students choose different term settings? In this study we tried to use the Sankey diagram to answer these questions. Comparing to the network graph or parallel coordinates plot, Sankey diagram provides a better graphical summary for this type of data.
