The massive rise in Computer Science enrollments in both traditional classroom courses and in Massively Open Online Courses (MOOCs) shows the enormous opportunities in engaging students to learn programming. While the number of students in CS courses continues to increase, there has been no concomitant increase in the number of instructors for such courses. This leads to a completely lopsided learning environment where the already-stretched instructor is pressed to spend more time on ancillary tasks like grading and course bookkeeping. CodeWorkout is an online drill-and-practice system with course management features that aims to address these issues. CodeWorkout hosts an online repository of programming questions that instructors can incorporate into their courses. It also provides instructors with a facility to create their own programming questions so that exercises can be tailored according to the needs of the class. CodeWorkout has an open gradual engagement model that allows students who are not enrolled in a course to use it. CodeWorkout also creates an open environment for instructors to collaborate by sharing exercises that they create. CodeWorkout has been used in four courses at Virginia Tech. It has been shown to significantly improve the student's skills in introductory programming through providing a number of online practice questions.
