RStudio's free tools provide more than an ecosystem for doing data science; they provide an ecosystem for teaching data science. RStudio Cloud provides an easy to access compute environment that your students can use from minute one, no downloads or installation required. You can use RStudio Cloud to create a shared class space stocked with projects to fork and data sets to use. Packed into RStudio Cloud is a curriculum of self-paced interactive tutorials that cover the basics of the Tidyverse, which frees you up to focus on teaching how to apply R to your subject area (the tutorials cover the same ground as R for Data Science and are written by its authors). You can create your own interactive web tutorials with the learnr package, which transforms R Markdown documents into shiny apps that let students write, run, and submit their own code for feedback. Supporting all of this is the Tidyverse, a clear, coherent system for doing data science in R that is easy to teach and easy to use. This talk will provide a quickstart to using these tools as a foundation for your own data science course.
