A Cloud-based Learning System for Java']Java Programming Class

With the advance of the cloud computing technology, online-programming services that can be available through a Web browser have been widely spread. In a programming class, a teacher can efficiently manage each students' progress by introducing such an online-programming service to the students. In this study, we design and implement a cloud-based Java learning system for effectively teaching Java programming skills to students in a class. Our proposed Java programming learning system provides a function of classifying students into some groups based on the similarity of compile/runtime errors of Java program so that a teacher can grasp individual students' progress for Java programming exercises in the class. In the experiment using our prototype, we evaluated the feasibility of the proposed cloud-based Java learning system in terms of the capability of classifying students into some groups based on the similarity of compile/runtime errors of Java program as well as the usability evaluation.
