Abstract
Research in education highlights the importance of exposing student data to teachers, who can use this information to provide students with timely and accurate assistance. As digital technologies become more commonly used in classrooms, we have an opportunity to collect and communicate student data to teachers in real-time. However, little research has explored how to effectively visualize student data for teachers during class. In this work, we partner with the non-profit company Enlearn to design real-time visualizations of student data collected through their tablet-based software. We characterize the domain problem, design appropriate data abstractions, and present two new visual encodings to support teacher tasks. Informal feedback suggests that our visualizations would be valuable for teachers, and we aim to formally study our designs with classroom teachers in the future.
