Learning to write good computer code is a difficult task for introductory programming students. Students can learn what constitutes good programming practice, but actually writing a program requires a different kind of experience. Hence, programming assignments are an integral part of the learning experience in introductory programming courses. Instructors assign programming tasks to students as solo work with strict warnings against collaboration. A student in an introductory programming class may excel at theoretical assignments like tests and quizzes and yet struggle through programming assignments.
