RunCode is built and evaluated in real university courses. Randomized studies conducted through the platform examine how automated and AI-generated feedback influences programming behavior, problem solving, engagement, and learning.
Students who had previously received personalized AI feedback completed later programming tasks 6.25 minutes faster on average when AI support was no longer available, after accounting for pre-test performance.
Read the ICCE 2023 studyIn a randomized study with introductory programming students, learners who had received real-time AI feedback continued to reduce non-compiling submissions significantly faster across consecutive attempts after the AI feedback was disabled.
Read the EC-TEL 2025 studyResearch conducted with RunCode has received award nominations at leading conferences in AI in education, learning analytics, and computing education.

I was a complete beginner when I started. RunCode gave me a place to practice, make mistakes, and keep trying until I understood what I was doing. It really helped me build confidence in programming.
I use RunCode to teach my students. The ability to share code snippets and class assignments with a single link has been a game-changer for my classes. In my research I am investigating how to use RunCode to improve student learning.
RunCode gave us a practical way to conduct programming education studies in several Philippine universities. It supported both student practice and research data collection, and the results of the study were later published in research papers.
The goal of our research is to improve the understanding of how people learn programming.
