What are best practices for students submitting their tutorial answers?

[davidkane9]

Every instructor needs a method for ensuring that her students have completed their assigned tutorials. What are current best practices?

1. Based on learnhash by @rundel, some people --- examples include qsslearnr by @mattblackwell and tutorial.helpers by me --- allow students to create pdf/html/rds files of their answers.

2. It seems possible to use some CSS magic to make tutorials printable. Thanks to @siebrenf and @gadenbuie.

The problem with 1) is that it requires a lot of difficult to test/maintain infrastructure. I have no experience with 2) but it seems very hacky to just paste in some CSS code. Questions:

1. Are there any other approaches that people are aware of?

2. Does RStudio have any plans about this? @gadenbuie mentioned the possibility of incorporating 2) into the learnr package itself, but that was more than two years ago and the PR for doing so was not accepted.

Thanks!

I provided my own set of answers to this question with the tutorial.helpers package, now on CRAN. Feedback is welcome!
