Making failure the mother of success

Do students really welcome failure, the mother of success? This paper reports the implementation of a trial-and-failure learning strategy, in both entry and senior level computer science classes. The idea is simple: given a sophisticated course project, let students try project submissions as many times as they want before the project deadline. For each submission, a thorough inspection is performed by an automated grading system called APOGEE. A student project has to accomplish not only the functional requirements but also many desired quality attributes such as robustness and security. In 2009, the trial-and-failure strategy has been adopted by four universities in five class sections. We report some interesting observations from student survey results, e.g., one can find out if factors like students´ positive experiences of programming, choice of programming language, years of working experience, and instructors are predictive variables for positive attitudes toward the trial-and-failure learning experience as a whole.
