Abstract
In this paper the use of an open-source online learning platform to aid in teaching and assessment of computer programming in large classes is discussed. The pedagogical philosophy of how the subject of computer programming is taught is presented. Based on the skills and learning processes that are identified for effective teaching of computer programming, a strategy for employing modern web technology coupled with an automated assessment capability to meet these goals is discussed. The paper describes the technology and implementation of the learning platform and new methods for automated assessment of programming assignments and exams. Finally, the application of the system to achieve the pedagogical goals and the benefits of using the system for teaching large classes is reported.
