Automatically Generated Visual Profiles of Code Solutions as Feedback for Students

Providing students feedback on their exercise solutions is a crucial element of computer programming education. Such can be generated automatically and take various forms. This paper introduces proposes the use visual profiles code as form to students. The are based frequency elements belonging six distinct classes. core idea visually compare profile student-submitted solution range accepted (including both reference provided by instructors submitted who successfully passed same earlier). advantages proposed approach demonstrated number examples real-world data.
