I use the Rcmdr package in the introductory statistics course I teach for non-majors. For the past several years I've used video tutorials, in addition to written documents covering the same material, for the lab portion of the course where students use Rcmdr and R to analyze data. All course materials are made available via a content management system that allows me to analyze to what degree students are utilizing various delivery mechanisms. This poster will present how I've assembled the video tutorials as well as usage patterns over the last three course offerings. The associations between tutorial usage type/frequency and student performance in the course are also explored.
