Impact of Hour of Code: A Five Year Study

This research aims to understand the impact of Hour of Code in consecutive 5 year since it was first launched in 2013. College students in an introductory computing course were surveyed about their attitude toward programming and their programming knowledge. We found evidence of positive impact of Hour of Code on student attitude toward programming as well as their understanding of programming knowledge. This study provides a foundation upon which further investigation into gender differences in computing can be based as well as improving attitude, knowledge, and interest in computer programming.
