Over the past several years, the University of Kentucky has built a robust analytics infrastructure to support the use of real-time learning data to improve student academic success. In spring 2017, we piloted a personalized direct messaging program built on a Caliper-formatted Canvas data stream in several large STEM courses with traditionally high failure rates. This presentation will include an overview of UK’s technical architecture, a description of the pilot program, and a discussion of our first semester results and planned next steps.
