gradethis is an R package that provides automated grading and feedback for coding exercises in learnr interactive tutorials. It enables instructors to check student code submissions and deliver immediate, customized feedback at scale.
The package offers two grading approaches: comparing student code against a model solution for pattern-based feedback, or writing custom testing logic to catch and respond to specific mistakes. This flexibility allows instructors to provide targeted feedback messages that guide students toward correct solutions without requiring manual review of each submission. gradethis is specifically designed to integrate with the learnr tutorial system for teaching R programming.
