Teaching Visualization Literacy Crash Course

This two-part workshop is designed to help faculty and instructors improve student success through increasing the data visualization literacy of students. The goal of the workshop is to provide training and resources to instructors to be able to teach students how to create well-designed visualizations in order to communicate research findings clearly and effectively. Part I of the workshop covers best-practices in visualization, effective visualization design, pedagogical considerations, and evaluation methods for helping students become better communicators using data visualization. Part II covers how to use Tableau in the classroom.
