Welcome to the “Crowd Layers” dashboard, a public service for ​Capturing and Reporting Open Web Data for Learning Analytics, Annotation, and Education Researchers ​(CROWDLAAERS). This real-time dashboard visualizes group – or ​crowd​ – discourse ​layers​ added via Hypothesis open web annotation to online documents. Developed by researchers at the University of Colorado Denver, CROWDLAAERS visualizes social learning analytics associated with open and collaborative web annotation. The dashboard has been iteratively designed in partnership with educators and researchers to support the social life of reading and the social life of documents across the open and annotated web.
