The Grand Challenges for Assessment in Higher Education project is a collaborative effort of 10 endorsing organizations and over 400 volunteers to increase the extent to which assessment (1) supports equity; (2) is visible, actionable, and drives innovation; and (3) guides rapid improvements in pedagogy (Singer-Freeman and Robinson 2020). Several implementation teams were created to carry out this work, including the Data Visualization Team, which was tasked with creating and disseminating data visualization and data story resources and increasing the use of data visualizations and data storytelling. Data visualization refers to the “visual representation of statistical and other types of numeric and non-numeric data through the use of static or interactive pictures and graphics” (Gatto 2015, p. 5). A closely related concept, data storytelling is the “ability to effectively communicate insights from a dataset using narratives and visualizations … [in ways that can] put data insights into context for and inspire action from your audience” (Cote 2021). Effective data visualization and storytelling can communicate findings quickly so that stakeholders can focus on implementation strategies rather than understanding the data. With greater engagement and understanding of assessment data, stakeholders are more likely to use the findings to guide resource allocations and decisions.
