Gamifying Software Engineering Tools to Motivate Computer Science Students to Start and Finish Programming Assignments Earlier

Abstract

<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Contribution:</i> Research has shown that computer science (CS) students who start programming assignments (PAs) early generally receive higher grades. This article presents and evaluates a gamification approach that utilizes software engineering tools to motivate CS students to start and finish PAs earlier. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Background:</i> CS can be difficult to learn because students often struggle with errors and how to properly test their code. For these reasons, it is essential that students start their PAs early. Furthermore, software engineering tools, such as version control and unit testing, are increasingly important for students to learn early in their career. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Intended Outcomes:</i> This gamification approach aims to motivate CS students to start and complete PAs earlier, as well as instill software engineering best practices. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Application Design:</i> To motivate students to start and finish assignments early, an open-source gamification system called the Leaderboard was developed. Using gamified points, the Leaderboard rewards students who pass PA unit tests well before the assignment is due. The system is fully automated using Github Classroom, a build server, and the Moodle learning management system. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Findings:</i> Results indicate students who used the Leaderboard did not start assignments significantly earlier; however, they finished assignments earlier, committed code more frequently, and passed more unit tests. The students found the Leaderboard to be motivating and passing unit tests was exciting for them.
