Joshua Rosenberg describes his one-day experience teaching R to 7th graders:
[T]he activity worked albeit, as a very gradual introduction to using R. In combination with starting with modest goals, having the right tools (R Studio Cloud, R Markdown, and a suitable data set), I think, helped to make this work. 7th-graders can (start to) use R. The goal that Alex and I have is for students to be able to analyze data that they collect (and already-collected scientific data).
Lucky kids. All I got was a scientific calculator.
